Degradation of Crude oil in different soils environment was monitored using two different species of plant extract namely moringa and Neem roots. Four different types of soil was investigation namely loamy, sandy, clay and silt soil all obtained from Niger Delta area of Nigeria as well as the Moringa and Neem roots including the alcohol and water media with the aims to extract the useful nutrient that can enhance microbial activities on crude oil degradation. The mass of 500g and 600g of the moringa and Neem roots fermented extracts were introduced into the various polluted soil types investigated and the result obtained show increase in degradation of Total Petroleum Hydrocarbon (TPH) with increase in time in all the soil types. Degradation of the TPH was more rapid in sandy soil environment and less in silt soil environment in moringa in water and alcohol as well as in Neem in alcohol and water media. The research work also revealed that degradation was faster in moringa in water than all others, showing the acceptability of moringa root as a major radiant for crude oil polluted environment. The aim of this research work is to examine the effectiveness of fermented moringa and Neem roots extract for remediation of crude oil polluted soils of different environment.

Abstract We report kinetics of Assam crude oil degradation by Pseudomonas aeruginosa AKS1 and Bacillus sp. AKS2, both isolated from Assam refinery sediments. The isolates exhibited appreciable degrees of hydrophobicity, emulsification index and biosurfactant production. Crude oil degradation efficiency of isolates was assessed in (1) liquid medium amended with 1% v/v crude oil and (2) microcosm sediments (125 mg crude oil/ 10 g sand). In liquid culture, the biodegradation rate (k) and half-life (t1/2) values were found to be 0.0383 day -1 and 18.09 days for P. aeruginosa AKS1, and 0.0204 day -1 and 33.97 days in case of Bacillus sp. AKS2. In microcosm sand sediments, the estimated biodegradation rate (k) and half-life (t 1/2) values were 0.0138 day -1 and 50 days for P. aeruginosa AKS1, and 0.0113 day -1 and 61.34 days in case of Bacillus sp. AKS2. The level of nutrient treatment in microcosm sand sediment was 125 µg N & 62.5 µg P/g sediment in case of P. aeruginosa AKS1 and 375 µg N & 37.5 µg P/g sediment in case of Bacillus sp. AKS2. In microcosms without inorganic nutrients, biodegradation rate (k) and half-life (t1/2) values were found to be 0.0069 day -1 and 100 days for P. aeruginosa AKS1 and for Bacillus sp. AKS2, the respective values were found to be 0.0046 day -1 and 150.68 days. Our data provides important information for predictive hydrocarbon degradation in liquid medium and contaminated sediments.
