This exploration evaluated the bioremediation potential of garbage of enzymes (GE) from fermented organic wastes on Fe, Co, Zn, Cu concentrations on crude oil polluted soil. The natural gas polluted soil was self-possessed from Agbura community of Bayelsa State. The crude oil polluted were divided into 6 groups. Group 1and 2 served as control and untreated soil samples respectively. Group 3 was treated with 30% of GE from fermented watermelon and pineapple wastes. Group 4 was treated with 50% of GE from plantain and banana wastes. Group 5 was treated with 70% of GE from plantain, watermelon, pineapple and banana wastes. Group 6 was treated with 100% of GE from plantain, watermelon, pineapple, and banana peels. Group 3, 4, 5, and 6 were treated for 30, 60, 90, 120, 150, and 180 days using 90 days GE from organic peel wastes. The Cu concentration in group 6 (91.05±0.0%) after treatment with 100% of GE were significantly higher than those of group 2 (17.34±0.02%). The Zn concentration in group 6 (83.25±0.03%) after treatment with 100% of GE were higher than those of group 2 (12.05±0.0%). The Co concentration in group 6(81.06±0.04%) after treatment with 100% of GE were higher than those of group 2 (17.33±0.02%). GE from organic peels demonstrated percentage Fe, Cu, Zn, and Co percentage removal from crude oil polluted soil after treatment, hence could be used as bioremediation tool in crude oil spill cleanup.
