Comparative Study on Bioremediation of Crude Oil Polluted Soil Using Water Hyacinth (Eichhornia Crassipes) Compost and Groundnut (Arachis Hypogea) Shell
Abstract
Given the far-reaching effects of oil spills on ecosystems and human health, the cleanup of soil polluted with crude oil is an urgent environmental problem. Crude oil, composed of various hydrocarbons, poses a significant threat to soil quality and biodiversity. The aim of this study is to compare bioremediation study of crude oil polluted soil using water hyacinth (Eichhornia crassipes) compost and groundnut (Arachis hypogea) shell. The standard spread plate technique was used to study the growth dynamics of microorganisms. Bacillus sp (18.40%), Proteus sp (4.48%), Pseudomonas sp (14.43%), Serratia sp (4.48%), Micrococcus sp. (13.43%), Arthrobacter sp. (21.00%), and Staphylococcus sp. (23.88%) were the bacterial isolates identified whereas Aspergillus sp. (56.56%), Saccharomyces sp. (12.33%), Penicillium sp. (3.44%), Fusarium sp. (18.78%), and Rhodotorula sp. (8.88%), were the fungal isolates identified in the study. TPH reduced by 91.69% in the treatment with Soil +Crude oil + water hyacinth compost (SCWH), 90.37% in the treatment with Soil + Crude oil + Groundnut shell (SCGS), 87.12% in the treatment with Soil Crude, and 85.64% in the treatment with Sterile Soil + Crude oil. All heavy metals studied had decreased concentration in the treatments within the period. This research looked into waste utilization for a cleaner environment as reckless dumping of these plant wastes constitute environmental nuisance. Cultivation of crops like groundnut, hamburger bean and mushroom farming should be encouraged as their wastes serve as potential candidate for remediation of polluted environment.
