Effects of Four Crude Oil Degrading Bacteria Strains on the Physicochemical Parameters of Water from River Erhioke, in Kokori, Delta State, Nigeria

This study investigated the effect of four crude oil degrading bacteria strains (Pseudomonas putidastrainAY001, Alcaligenes aquatilis B61, Winkia neuii B12 and Enterococcus casseliflavus AAOO-1) on the physicochemical parameters of water from River Erhoike, in Kokori, Delta State, Nigeria using appropriate standard methods. Results obtained show that The pH ranged between 6.3 and 7.3, the dissolved oxygen ranged between 5.80±0.10 and 10.00±0.20, the highest total petroleum hydrocarbon degradation rate was 70% and results showed that .Pseudomonas putida strainAY001 which had 70% crude oil degradation rate ranked the best among others, making it good indigenous bacteria with a great potential to perform bioremediation of hydrocarbon polluted environment
