The Impact of Bacteria and Biostimulants on Crude Oil Breakdown in Loamy Soil
Abstract: This study investigates the influence of bacteria and biostimulants—specifically Bryophyllum pinnatum leaves soaked in both water and ethanol—on the degradation of crude oil in loamy soil. A laboratory-scale bioremediation setup was employed using a batch reactor model and first-order degradation kinetics to assess total petroleum hydrocarbon (TPH) breakdown under controlled conditions. Various analytical tools and procedures, including gas chromatography (Agilent 6890) and microbial media such as nutrient agar and mineral …

Properties of Biostimulant of Ponderosa Lemon for Crude Oil Remediation in Soil Environment
Abstract: The effect of petroleum hydrocarbon on soil environment contributes to low performance of microbes and plant yield. This study investigates the potential of grape leaf (Ponderosa lemon) on hydrocarbon constituents of crude oil contaminated soil. Freshly harvested grape leaf was washed thoroughly with tape water thereafter rinse with distilled water, some portions kept for room-dried and another for sundried to vary the composition. Fixed masses of loamy soil samples of …

Bioremediation of Crude Oil-Contaminated Loamy Soil Using Plantain (Musa Paradisiaca) Stem Waste as a Biostimulant
Abstract: Crude oil contamination of soil is a pressing environmental challenge in oil-producing regions, especially in the Niger Delta of Nigeria. It degrades soil fertility, disrupts microbial ecosystems, and poses long-term ecological and health risks. Traditional remediation methods are often cost- prohibitive and environmentally intrusive, prompting the search for sustainable alternatives. This study investigates the potential of plantain (Musa paradisiaca) stem waste – a readily available agricultural byproduct – as a …

Comparison of Percentage Removal of Petroleum Hydrocarbon on the Effect of Biostimulant in Polluted Soil Environment Using Chromolaena odorata
Abstract: The investigation on the comparison of percentage reduction on polluted soil environment using chromolaena odorata as a bio-stimulant upon the effect of contact time revealed increase in percentage removal of total petroleum hydrocarbon (TPH). The rate of total petroleum hydrocarbon (TPH) removal was discovered to have been influenced y the mas of bio-stimulant dosage immersed or introduced into each of the bioreactor. However, as the mass of the bio-stimulant dosage …

Effect of Bacteria on Crude Oil Degradation in Loamy and Clay Soil for Water and Ethanol Biostimulant Extraction from Bryophylum pinnatum Leaf
Abstract: The effect of bacteria on crude oil degradation in loamy and clay soil for water and ethanol biostimulant extraction from Bryophylum pinnatum leaf was investigated to ascertain the potential of the bacteria counts in the bioreactors sampled. At the progressive phase, the bacteria counts were more with bioreactors induced with ethanol solvent extract as the volume of the dosage increases compared to the bioreactors induced with the water extract. The …

Effect of Microbial Species and Inoculum Dosage on Anaerobic Digestion
Abstract: This work aims at studying the effect of microbial species and inoculum dosage on anaerobic digestion of food waste using cattle rumen content as inoculum. Four different batch runs were carried out with different percentage inoculations which were (control sample), 25% dosage, 50% dosage and 75% dosage. To have both logical and scientific explanation why the inoculated samples had better performance than the control sample, microbial identification was carried out …
