    Bio-Removal of Vat Dye from Textile Effluent by Candida tropicalis and Candida apis Isolated from Soil
    (Expert Opin Environl Biol., 2015) Aransiola, S.A
    The bio-removal of textile effluent (Vat dye) by yeasts isolated from soil was studied. A total of 5 yeasts were isolated and identified from soil (using morphological and biochemical characterization) to remove vat dye from textile effluent. These isolates were screened by inoculating them into 500 ml conical flask each containing sterile mineral salt media and 20 mg of vat dye. Of these isolates, Candida tropicalis and Candida apis stood out as potential dye decolorizes after incubation. Candida apis and Candida tropicalis removed 90.6% and 84.1% of color from the textile effluent after incubating for 25 days at 37º C. The textile effluent treated had initial high concentration of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Nitrate, above the standard acceptable limit which is an indication of high contamination. All the isolates used performed efficiently in reducing the concentration of these parameters in the textile effluent at neutral pH of 7.0. The Yeast isolates (Candida apis and Candida tropicalis) exhibited good potentials in the treatment of textile effluent. Candiada apis reduced the BOD from 1,425 mg/l to 272 mg/l COD from 3,550 mg/l to 679 mg/l while the Nitrate was reduced from 255 mg/l to 65 mg/l and Candida tropicalis reduced the BOD from 1,425 mg/l to 312 mg/L, the COD was reduced from 3,550 mg/l to 780 mg/l and the Nitrate was reduced from 255 mg/l to 78 mg/L. These microbial isolates can be recommended as good candidates for treatment of waste water, especially textile waste water.

    Bioremoval of Zinc in Polluted Soil using Acalypha inferno
    (Research Journal of Environmental Sciences, 2015) Aransiola, S.A
    This study was to assess the Phytoextraction of Acalypha inferno for Zinc (Zn) contaminated soil. Stems were planted in five kilograms (5 kg) of the soil placed in each plastic pot having 0 ppm (control), 5, 10, 15, 20 and 25 ppm of Zn. The experiment was on for a period of 12 weeks. The results revealed that pH, phosphorous and moisture contents increased while nitrogen and organic carbon contents decreased in polluted soil remediated with Acalypha inferno. The plant compartments were analyzed for Zn uptake. Appreciable concentrations of Zn in different compartment of the plant was recorded, 7.12, 7.10 and 9.06 ppm for stem, root and leave, respectively. Bioconcentration Factor (BCF) and Translocation Factor (TF) was assessed. It was observed that more concentration of Zn was translocated from the roots to the leaves. The results obtained suggest that Acalypha inferno have phytoextraction ability and could be used in restoring soil polluted with zinc (Zn).

    Ecological Impacts and Toxicity of Micro and Nanoplastics in Agroecosystem
    (Springer Cham, 2023) Aransiola, S.A
    Micro- and nanoplastics are fragments of small plastics that are of sizes 1–5000 microns and <1 μm and consist of carbon and hydrogen atoms chained together by polymer. Micro- and nanoplastics are environmental pollutants, and their degradation depends on the properties of plastics, soil type, environmental condition, and microbial community. Their presence in the agricultural system is an emerging concern, which is basically attributed to the ability of the plastics to penetrate the soil and contaminate the soil plants, and microflora and fauna which thereby affect the food chain and security. Micro- and nanoplastics pollution in agrosystems originates from human activities (agricultural practices and anthropogenic sources) and natural sources (atmospheric inputs and flooding). Micro- and nanoplastics contamination of soil plants alters the chemical, physical, and biological properties of the soil ecosystem due to increased adsorption capacity when in combination with another organic contaminant. In agricultural ecosystems, micro- and nanoplastics affect soil microbial activity, microbial biomass, functional diversity, and the cycling process of plant nutrient elements in the soil, which have an indirect effect on plant seed germination and growth. When ingested or in association with the soil biota, micro- and nanoplastics can influence the agro-functionality through effects on soil root-associated microbiome and root symbionts, soil structure, nutrient immobilization, contaminant adsorption, and diffusion which can directly impact the fertility of the agricultural soil, plant qualities, and its yield. Microplastics excessive accumulation can directly result in toxic risk effects, including the interruption of the nutrient transport system by the obstruction of the pores in the cell wall, alter the community diversity, activity of the soil biota, and inhibition of nitrification. Microplastics and nanoplastics contribute to a major distribution of toxic and harmful compounds to soil plants, soil fauna, and photosynthetic organisms.

    Environmental Management and Uses of Vinasse-Review
    (Asian Journal of Current Research, 2016) Aransiola, S.A
    Vinasse is the fluid waste material got from the fermentation procedure of alcohol refining, from crude materials, for example, maize, beet, molasses or juices of cassava, sugarcane, among others by the utilization of yeasts at a proportion of 12-15 liters for each liter of alcohol which has inorganic and organic loads. Vinasse is used in farming for cheap supplements sources, enhancing specialists and animal feed past the confinement of high chemical oxygen demand (COD) and biochemical oxygen demand (BOD) and aggregate dissolved salts content even after the toxin expulsion treatment. This substance has a low pH and high COD, which can bring about environmental desertification when unpredictably utilized as compost. Likewise, underground water pollution is being seen in a few districts.

    Identification of methyl 18-methylnonadecanoate and bis(2-ethyl hexyl) phthalate as potential anticancer agents in Nauclea latifolia Smith through in silico molecular modeling and simulations
    (Next Research, 2025) Aransiola, S.A
    This study aims to explore the anticancer potential of compounds derived from Nauclea latifolia Smith using molecular docking and pharmacokinetic analysis. Gas chromatography-mass spectrometry (GC-MS) identified 25 bioactive compounds from the ethanol extract of N. latifolia leaves. Among these, methyl 18-methylnonadecanoate and bis(2-ethyl hexyl) phthalate were selected for further investigation due to their promising anticancer properties. The compounds were subjected to in silico molecular docking against two key cancer-related protein targets, ADAM17 and MAPK14, both implicated in cancer progression. The results revealed strong binding affinities for both compounds, suggesting potential inhibition of these targets. Pharmacokinetic profiling using Swiss ADMET indicated favorable drug-like properties, including high gastrointestinal absorption and non-carcinogenicity. These findings suggest that N. latifolia compounds, particularly methyl 18-methylnonadecanoate and bis(2-ethyl hexyl) phthalate, hold promises as candidates for anticancer therapy. Further in vitro and in vivo validation is required to confirm their efficacy and safety for therapeutic applications.

    Influence of Photoperiodic Levels of Skin Melatonization in Heteroclarias Fingerlings in Relation to Water Physico-chemical properties in Minna,
    (Nigeria. Malaya Journal of Biosciences, 2018) Aransiola, S.A
    An 8-week experiment was carried out to investigate the effects of photoperiodic levels on skin color of laboratory reared Heteroclarias fingerlings. Artificial lightning was used to simulate a range of photoperiod namely, continuous light period (24L: 0D), total darkness (24D: 0L), 12 hours of darkness and 12 hours of light (12D: 12L) and normal day and night period (control, i.e. ambient photoperiod). Adequately replicated representative number of Heteroclarias fingerlings were exposed to the various photoperiods and monitored for eight weeks. Results of physical observation of the fishes, following recommended fish skin color grading revealed that fingerlings reared in 24D: 0L had the darkest skin color, while those exposed to 24L: 0D had the lightest skin color. In addition, the fingerlings exposed to normal day and night period (control) had a light skin color while those exposed to 12L: 12D had a dark skin color. The physico-chemical parameters such as water temperature, pH, ammonia, biological oxygen demand and dissolved oxygen concentration were within the recommended range for fish culture and also indicated no significant differences(p>0.05) in all the treatments throughout the experimental period irrespective of photoperiodic condition. It is hoped that the findings of this study will guide commercial fish farmers in raising Heteroclarias fish according to the preferences of market demand with respect to skin color.

    Marine Bioprospecting for Sustainable Blue-bioeconomy,
    (Springer Nature Cham Switzerland, 2024) Aransiola, S.A
    This volume comprehensively discusses marine bioprospecting and its applications in the marine bioeconomy, specifically in clean energy generation, and in biomedical, industrial and agricultural sectors. The advent of modern technology, particularly advancements in deep-sea exploration and biotechnology, has enabled scientists to delve deeper into the ocean's depths and discover a treasure trove of unique organisms and compounds. This demonstrates that the rich history of human interactions with the oceans is firmly ingrained in marine bioprospecting. The blue-economy, which is a more accurate name for the systematic search for valuable substances and organisms in the water, has gained popularity in recent years as a possible route for sustainable economic development. One of the key driving factors behind marine bioprospecting is the growing realization that marine organisms possess unique biochemical compounds with the potential to revolutionize various industries. These compounds include novel enzymes, antimicrobial agents, bioactive molecules, and even potential pharmaceuticals. Readers will learn about the applications of these discoveries in bioremediation, wastewater treatment, and biofuel production, as well as the identification of natural substitutes for things that are detrimental to the environment, which include biodegradable plastics derived from marine microorganisms. The primary audience for the book will be governmental and international organizations, professionals, and economists, while the secondary audience will be professors and researchers in the fields of Chemistry, Biotechnology, Environmental Microbiology, and general Ocean Sciences.

    Microbiological, Nutritional, and Sensory Quality of Bread Produced from Wheat and Potato Flour Blends
    (International Journal of Food Science, 2014) Aransiola, S.A
    Dehydrated uncooked potato (Irish and sweet) flour was blended by weight with commercial wheat flour at 0 to 10% levels of substitution to make bread. Comparative study of the microbial and nutritional qualities of the bread was undertaken. The total aerobic bacterial counts ranged from 3.0 × 105 cfu/g to 1.09 × 106 cfu/g while the fungal counts ranged from 8.0 × 101 cfu/g to 1.20 × 103 cfu/g of the sample. Coliforms were not detected in the bread. Bacteria isolated were species of Bacillus, Staphylococcus, and Micrococcus while fungi isolates were species of Aspergillus, Penicillium, Rhizopus, and Mucor. The mean sensory scores (color, aroma, taste, texture, and general acceptability) were evaluated. The color of the bread baked from WF/IPF2 (wheat/Irish potato flour, 95:5%) blend was preferred to WF (wheat flour, 100%) while WF/SPF1 (wheat/sweet potato flour, 100%) and WF/IPF1 (wheat/Irish potato flour, 90:10%) aroma were preferred to WF. However, the bread baked from WF, WF/IPF2 (wheat flour/Irish potato flour, 95:5%), and WF/SPF2 (wheat/sweet potato flour, 95:5%) was more acceptable than other blends. The use of hydrated potato flour in bread making is advantageous due to increased nutritional value, higher bread yield, and reduced rate of staling.

    Phycoremediation of Manganese by Spirogyra and Richterella sp. Isolated from Pond
    (Journal of Global Agriculture and Ecology, 2015) Aransiola, S.A
    Heavy metals are non degradable pollutants and must be removed or reduced to acceptable limits before discharging into the environment to avoid threats to living organisms. This study was carried out to assess Manganese removal efficiency of Richterella and Spirogyra species isolated from ponds. The Manganese removal efficiency of the two algae were investigated for the period of 28 days at room temperature (28±2ºC) and regular light. The percentage Manganese removal on day 28 by Richterella specie was 90.3% and 87.1% by Spirogyra species. The optimum phycoremediation pH was 9 which recorded the same value of Manganese removal as above. The rate of removal of Manganese on day 14 by Richterella species was 89.4% and 86.1% by Spirogyra specie. Richterella and Spirogyra species were found to be effective in Manganese removal but Richterella species was more effective. Therefore the use of Richterella species for phycoremediation of Manganese should be encouraged.

    Production of Biosurfactants Using Pseudomonas aeruginosa for Biodegradation of Herbicide.
    (The International Journal of Biotechnology, 2019) Aransiola, S.A
    This study was aimed at isolating Pseudomonas aeruginosa from the soil to produce biosurfactant for degradation of herbicide. The soil sample was collected from oil polluted site in mechanic workshop, Minna, Niger State, Nigeria and transferred to the microbiology laboratory of the University in a sterile polyethylene bag. Pseudomonas aeruginosa was isolated from the soil and identified using microbiological and biochemical assays. The isolate was screened for biosurfactant production using haemolytic assay, drop collapse, oil spreading and emulsification test. Biosurfactant production was carried out using mineral salt medium for ten days. The ability of the biosurfactant produced by P. aeruginosa in degrading herbicide was tested on five concentrations of herbicide (5%, 10%, 30%, 50%, 70%) and the results showed biodegradation percentages as 56.4%, 53.1%, 32.6%, 29.8% and 26.2% respectively revealing that degradation was higher at lower concentrations. This suggests that herbicide could be biodegraded especially at low concentrations using biosurfactant produced by Pseudomonas aeruginosa.
