    Anaerobic digestion and agricultural application of organic wastes
    (Advances in Environmental Research, 2018) Aransiola, Sesan Abiodun
    The anaerobically digestion and agricultural application of organic wastes was conducted using food wastes and cow dung. Twenty kilograms each of the feed stocks was added into two 30 liters-capacity batch digesters. The anaerobic digestion was carried out within a temperature range of 25-31°C for a retention time of 51 days. The results showed a cumulative gas yield of 5.0 bars for food waste and no gas production for cow dung within the retention time. Bacteria such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Proteus vulgaris and Clostridium sp were isolated. Fungi isolated included Aspergillus niger, Aspergillus nidulan, Trichophyton rubrum and Epidermophyton flocossum. The nondispersive infrared (NDIR) analysis of the biogas produced confirmed that the gas consisted of CH4, CO2 and H2. Statistical analysis revealed there was no significant correlation between temperature and biogas produced from the organic wastes (r= 0.177, p = 0.483).The organic wastes from the biogas production process stimulated maize growth when compared to control (soil without organic waste) and indicated maximum height. The study therefore reveals that food waste as potential substrates for biogas production has a moderate bio-fertilizer potential for improving plant growth and yield when added to soil.

    Bacterial biofilm formation and anti-biofilm strategies
    (Research in Microbiology, 2024) Aransiola, Sesan Abiodun
    Bacteria are ubiquitous prokaryotes. They are involved in biofilm formation and also have the ability to produce anti-biofilm products for biofilm mitigation. This special issue entitled: “Biofilms- community structure, applications and mitigation” of the journal Research in Microbiology was designed to discuss the flexibility of bacterial biofilms and their products under particular circumstances. Given that quorum sensing (QS) controls biofilm growth in some situations, especially for pathogenic bacteria antibiotic evading strategies. In Gram-negative bacteria, N-acyl homoserine lactones are the major quorum sensing signaling molecules. Another approach to prevent bacterial biofilm formation may be to inhibit the QS-regulated activities using quorum quenching (QQ). In this context, QS inhibitors and QS enzymes are important because they, respectively, interfere with signal creation, perception, or degradation and chemical modification. There have been numerous reports of QQ enzymes from bacteria. Treatment failure and recurrent staphylococcal infections are also brought on by biofilm development, which boosts an organism's ability to withstand antibiotics and is thought to be a virulence factor in patients. However, polyphenol quercetin antibiofilm activity is naturally available against drug-resistant Staphylococcus aureus.

    Bioactive Compounds of Insects for Food Use: Potentialities and Risks
    (Journal of Agriculture and Food Research, 2023) Aransiola, Sesan Abiodun
    Insects are an alternative source of human and animal food that not only have nutritional characteristics and important bioactive compounds, but also can help reduce the impact of chronic non-communicable diseases; thus, derivatives from insects are a great contribution to the food and pharmaceutical industry. The aim of the present work was to highlight the chemical composition, main bioactive compounds, and anti-nutritional factors present in some insects and their applications as raw materials in the food and pharmaceutical industry through the analysis of different studies. Results indicated that entomophagy was included in the diet of many regions in the world and that it is going to become a significant component in the food industry. It was also found that bioactive compounds with potential functional properties within the chemical composition of insects such as an appropriate digestibility between 54 % and 86 %, peptides between 35 % and 77 % and other nutrients such as proteins and carbohydrates that can be a great contribution to nutrition and reduce the risk of chronic non-communicable diseases. Global agencies are of the opinion that edible insects are the viable option to over the food scarcity. However, use of food matrices from insects raises safety issues, such as anti-nutritional factors allergenicity and capacity to harbor toxins such as oxalates, tannins, alkaloids, phytates and saponins or pathogens and heavy metal. Insights presented in this work are useful to insect business (such as farmers, producers of edible insect products and consultants), researchers, and policy makers. Such insights can be an initiative for insect food companies in many ways, such as to forge collaborations with different bodies (researchers, peoples, government), improve perception of insect consumption, promote market acceptance, identify new and native edible insect species, make ecologically sustainable insect food companies, produce nutritious and delicious insect-based foods, etc.

    Crude Oil BiodegFlehradation Potential of Lipase Produced by Bacillus subtilis and Pseudomonas aeruginosa Isolated from Hydrocarbon Contaminated Soil
    (Environmental Chemistry and Ecotoxicology, 2024) Aransiola, Sesan Abiodun
    Microbial biodegradation of oil pollutants and their derivatives has become the most environmental-friendly method in the developing world. The aim of this study was to evaluate crude oil biodegradation potential of lipase produced by indigenous bacteria from oil contaminated soil. Indigenous bacteria isolates were identified as species of Bacillus subtilis and Pseudomonas aeruginosa, the isolates were able to produce lipase as revealed in their zone of clearance on tween 80 agar plates and the presence of lipase produced by the two bacteria were further confirmed using spectrophotometric analyses. Lipase produced by B. subtilis showed maximal lipase activity at pH 8 and 40 while the enzyme produced by P. aeruginosa showed maximal lipase activity (U/mL) at pH 8 and 50 when subjected to various pH and temperature respectively. Lipase produced by B. subtilis recorded 8.11 ± 0.70 of crude oil degradation in mineral salt medium within 28 days, while that of P. aeruginosa recorded 15.6 ± 0.03 of crude oil biodegradation. The GC–MS analysis of the crude oil treatment showed complete mineralization of several compounds, and also showed peak reduction which indicates lipase efficiency in the degradation of hydrocarbons. As revealed by GC–MS analysis, out of the 8 hydrocarbons identified in an undegraded oil, 5 were completely degraded by the enzyme activities while 2 (toluene and methyl, cyclopentane) were identified with hydrocarbons treated with lipase. The enzymes produced by B. subtilis and P. aeruginosa can serve as useful product for bioremediation of crude oil contaminated soil.

    Enhanced microbial degradation of PET and PS microplastics under natural conditions in mangrove environment.
    (Journal of Environmental Management, 2022) Aransiola, Sesan Abiodun
    In-situ bioremediation of mangrove soil contaminated with polyethylene terephthalate (PET) and polystyrene (PS) microplastics was investigated using indigenous microbial consortium with adequate capacity to degrade the plastics. Eight (8) bacteria were isolated from plastic/microplastic-inundated mangrove soil and screened for the ability to degrade PET and PS microplastics. Optical density at 600 nm and colony forming unit counts were measured to evaluate the growth response of the microbes in the presence of PS and PET microplastics at different times of exposure. Structural and surface changes that occurred post biodegradation on the microplastics were determined through EDS and SEM analysis. The obtained results demonstrated the elongation and disappearance of peaks, suggesting that the microbial consortium could modify both types of microplastics. The overall results of the microplastic degradation showed varied degrees of weight loss after 90 experimental days, with the treated plot recorded 18% weight loss. The augmented soil was increased in the concentrations of Si S, and Fe and decreased in the concentrations of C, O, Na, Mg, Al, Cl, and K after bioremediation.

    Exploring the Potential of Fungi in the Bioremediation of Pharmaceutically Active Compounds. Front. Microbiol. Sec. Microbiotechnology
    (Front. Microbiol, 2023) Aransiola, Sesan Abiodun
    The ability of fungal species to produce a wide range of enzymes and metabolites, which act synergistically, makes them valuable tools in bioremediation, especially in the removal of pharmaceutically active compounds (PhACs) from contaminated environments. PhACs are compounds that have been specifically designed to treat or alter animal physiological conditions and they include antibiotics, analgesics, hormones, and steroids. Their detrimental effects on all life forms have become a source of public outcry due their persistent nature and their uncontrolled discharge into various wastewater effluents, hospital effluents, and surface waters. Studies have however shown that fungi have the necessary metabolic machinery to degrade PhACs in complex environments, such as soil and water, in addition they can be utilized in bioreactor systems to remove PhACs. In this regard, this review highlights fungal species with immense potential in the biodegradation of PhACs, their enzymatic arsenal as well as the probable mechanism of biodegradation. The challenges encumbering the real-time application of this promising bioremediative approach are also highlighted, as well as the areas of improvement and future perspective. In all, this paper points researchers to the fact that fungal bioremediation is a promising strategy for addressing the growing issue of pharmaceutical contamination in the environment and can help to mitigate the negative impacts on ecosystems and human health.

    Micro and Nanoplastics in Environment – Degradation, Detection, Ecological Impact.
    (International Journal of Environmental Research, 2024) Aransiola, Sesan Abiodun
    Microplastics and also nanoplastics are tiny pieces of plastics that have been a rising source of worry due to their ubiquitous occurrence and possible environmental effect. This article dives into the presence, origins, and degrading processes that cause microscopic and nanoplastics in the natural environment, illuminating the complexities of this worldwide issue. Micro- and nanoplastics have become increasingly common in the environment during the last few decades. Microplastics have negative effects on aquatic habitats when they enter water bodies. Atmospheric deposit (microplastics are substances that have been found in the upper atmosphere, primarily originating compared to the breakdown of bigger polymers and the everyday use of car tires), splitting at sea in the marine environment, materials are confronted with constant both chemical and physical stressors, leading to dispersion into smaller pieces along with land-based runoff; storm water drainage from urban areas can transport polymer content, and particle size all impact the breakdown of micro- and nanoplastics. While plastics are known for their durability, they can be degraded through a variety of mechanisms, including mechanical weathering, photodegradation, corrosion by chemicals, biological degradation, and fragmentation. The widespread presence and persistence of micro- and nanoplastics in the surroundings has raised concerns about their potential effects on ecosystems and human health. Particles like these can be consumed by a variety of creatures, ranging from zooplankton to bigger marine animals, resulting in the spread of plastics throughout the food chain. The occurrence and degradation of micro- and nanoplastics is therefore focused in this review.

    Micro and vermicompost assisted remediation of heavy metal contaminated soils using phytoextractors
    (Case Studies in Chemical and Environmental Engineering., 2024) Aransiola, Sesan Abiodun
    Heavy metals (HMs) contamination is a serious environmental concern in different parts of the world. In this study, two indigenous phytoextractors, Sida acuta and Melissa officinalis L. were used and assisted with plant growth promoting bacteria (PGPB) and vermicompost by-product (vermicast) produced for remediation purposes. The concentration of heavy metal accumulation in plants were determined using atomic absorption spectrophotometry and analyzed by canonical discriminant analysis (CDA). Pre- and post-remediation analysis of the physico-chemical properties of the soil was conducted. M. officinalis L components in the primary location were able to remove HMs, particularly lead (Pb) and cadmium (Cd) with metalloid (arsenic (As) concentration in plant ranges from 0.09 to 4.39 ppm, 0.07–10.35 ppm and 0.007–0.33 ppm, correspondingly. In the contaminated soil after remediation, the amount of Pb varied from 5.88 to 12.37 ppm, Cd concentration was between (0.026–0.58 ppm) while As was between 0.32 and 5.48 ppm. HMs concentration of soil remediated with Sida acuta had Pb, Cd, As varied from (1.68–10.7 ppm), (0.002–0.43 ppm) and As (0.27–3.79 ppm) individually. The organic carbon and nitrogen concentration before (C: 0.27; N: 0.01) and after (C:6.40; N: 0.70) the remediation process showed a significant increase, pointing to less contaminated soil. The role of vermitechnology in phytoremediation is important and could be employed to restore a contaminated soil with HMs as reported in this study.

    Microbial-aided Phytoremediation of Heavy metals Contaminated Soil: a review
    (European Journal of Biological Research, 2019) Aransiola, Sesan Abiodun
    Anthropogenic exercises as well as industrial enterprise and agricultural practices contribute considerably to the degradation and contamination of environment that considerably affects the soil. The normal physical and chemical know-how soil washing used for soil remediation render the land useless as a medium for plant growth, as they take away all biological activities. Others are labor-intensive and have high maintenance value phytoremediation, a cheaper and sustainable in situ remediation technique was so thought of. This data can enable proposing solutions to issues of contamination and eventually convalescent sites and soils. However, plants don't have the aptitude to degrade several soil waste matters particularly the organic pollutant. It's so imperative to require advantage of the degrading ability of soil microorganisms. This review so focuses on phytoremediation techniques improved by microbial colonies.

    Niger Delta Mangrove Ecosystem: Biodiversity, Past and present pollution, threat and mitigation
    (Regional Studies in Marine Science, 2024) Aransiola, Sesan Abiodun
    The Niger Delta mangrove ecosystem, located in Southern Nigeria, is a vital wetland area encompassing diverse ecological zones such as coastal inland zone, middle mangrove swamp forests, freshwater swamps, and landward mangrove zone. This ecosystem covers approximately 1900 km² and plays a crucial role in supporting several biodiversity and providing essential ecosystem services to millions of people in the region. However, the Niger Delta mangroves face significant threats from anthropogenic activities like oil exploitation, deforestation, and urbanization, leading to their depletion and loss. The degradation of mangrove forests not only impacts biodiversity but also jeopardizes the livelihoods of coastal communities that depend on these ecosystems for food and resources. The disappearance of mangroves leaves communities vulnerable to tidal inundation and extreme weather due to the loss of natural defenses. To address these challenges, various mitigation strategies are essential. These include the enforcement of laws, public awareness campaigns, educational programs, research initiatives to understand ecological dynamics better, and data collection to inform evidence-based management strategies. Additionally, implementing zoning regulations, integrated coastal zone management plans, and monitoring systems can help protect and restore the Niger Delta mangrove ecosystem. Efforts towards restoring and conserving the Niger Delta mangroves are crucial not only for safeguarding biodiversity but also for ensuring sustainable resource management practices and mitigating environmental threats. By adopting a holistic approach that combines scientific research, community engagement, policy interventions, and conservation efforts, it is possible to preserve this unique ecosystem for future generations while promoting sustainable development in the region.

    Phytochemicals and Anticancer Activity of Methanol Extract of Trigonella foenum-greacum Seed on Breast Cancer Cell Lines
    (South African Journal of Botany, 2023) Aransiola, Sesan Abiodun
    This study was aimed to examine the anticancer potential of Trigonella foenum-greacum seed methanol extract by analyzing its phytochemicals and its breast cancer cells effects. The anti-cancer efficacy of the extract was tested on fibroblast cells and MCF-7 through various cellular assays, including apoptosis, mitochondrial membrane potential, reactive oxygen species, cell cycle distribution, and cell cytotoxicity assay were all investigated. By using GC-MS analysis, fifty-five bioactive compounds were identified in the extract. When the cancer cell lines were treated with the extract, the typical apoptotic morphology was observed, this resulted in a dose-dependent reduction of cancer cell migration and adhesion. Flow cytometry studies revealed that the extract significantly induced apoptosis by triggering a change from G2/M to polyploidy (>G) at greater doses. Furthermore, the extract increased mitochondrial depolarization and ROS levels. This study demonstrates the extract's anti-cancer properties and highlights the need for further analysis to understand how Trigonella foenum-greacum seed extract induces program cell death through multiple signaling pathways at varying concentrations.

    Phytoremediation in Food Safety: Risks and Prospects
    (CRC press, 2024) Aransiola, Sesan Abiodun
    Food and food products are essential commodities globally and the factors affecting its general acceptability need to be critically reviewed. Phytoremediation is one of the most cost-effective remediation options, but as a stand-alone technology, it is often not lucrative enough to make it appealing for farmers, especially in economically vulnerable regions. Phytoremediation is a costeffective and environmentally friendly technology, but if most of its postharvest protocols are not handled professionally, it could become a threat to food safety. Plants possess the natural ability to accumulate nutrients and any contaminants present in the soil. However, this technology when used for remediation processes accumulates the pollutants from the soils through the root and mostly store these toxicants in the plants’ edible parts. When these are not checked or extracted from the plants, they pose a danger to human and animal health if they enter the food chain and are consumed. This book, Phytoremediation in Food Safety: Risks and Prospects, was conceived to provide in-depth information on the role of phytoremediation in food safety. Generally speaking, soil is polluted with both organic and inorganic contaminants and there is a need to employ an environmentally friendly technology in its remediation processes. Phytoremediation involves the use of green technology plant to remediate the polluted soils. The book is divided into three sections. Section 1 is titled “Prospects of Phytoremediation for a Safe Environment and Safe Food,” section 2 is “The Risks of Phytoremediation in Food Safety,” and section 3 is “Bringing Safe Foods Home through Phytoremediation.” The chapters were contributed by 68 academicians, scientists, and researchers from nine different countries (the United Kingdom, Hong Kong, Nigeria, India, the United States, Australia, Canada, Germany and Malaysia) across the world.

    Phytoremediation of Lead Polluted Soil by Glycine max L.
    (Applied and Environmental Soil Science, 2013) Aransiola, Sesan Abiodun
    A study was designed to assess the phytoextraction potential of Glycine max L. for lead (Pb). Pots experiment was conducted. Viable seeds were planted in 5 kg of soil placed in each plastic pot having 0 ppm (control), 5 ppm, 10 ppm, 15 ppm, 20 ppm and 25 ppm of Pb respectively. The study was carried out for a period of 12 weeks under natural conditions. Physicochemical properties of the soil were determined using standard methods. The results revealed that pH, phosphorous and moisture contents increased while nitrogen and organic carbon contents decreased in polluted soil remediated with Glycine max L. compared to the unpolluted soil. Leaf, stem, seeds and roots of the plant were analyzed for Pb uptake after 12 weeks. The plants mopped up substantial concentration of Pb in the above plant biomass of the seeds (4.2 mg/kg), stem (1.37 mg/kg) and leaves (3.37 mg/kg) compared to concentrations in the roots (1.53 mg/kg). The phytoextraction ability of the plant was assessed in terms of its bioconcentration factor (BCF) and translocation factor (TF). It was observed that the levels of Pb in the roots and shoots after 12 weeks showed that more bioavailable pool of Pb was translocated from the root to seeds, leaves and stem in that order. The results obtained suggest that the plant has phytoextraction ability and could be used in restoring soil polluted with Pb
