Enhanced Biodegradation of Oil Products by Some Microbial Isolate Supplemented with Heavy Metals

Aniruddha Sarma and Hemen Sarma

Abstract:
Three native strains, identified as Staphylococcus sp., Acinetobactor lwoffii and Enterobacter agglomerans were isolated from crude oil contaminated field and the aim of this research was to select potential soil microbial strain that could be effective in the bioremediation of crude oil compounds. Crude oil degradation performed by the isolates incubated in the shake flask culture and analysis of the results address that Acinetobactor lwoffii, accelerated cleanup most effectively, degrading oil sludge by a total of 93.78% in compare to Staphylococcus sp. (17.39%) and Enterobacter agglomerans (16.49%). Furthermore enhanced biodegradation potential of the isolates were studied by adding Mn and Cu and results indicated that supplemented metal increased degradation of crude oil products. In the present study, three bacterial strains AS1, AS2 and AS3 were termed and isolated through long cultivation with crude oil as the single carbon source. The three strains were identified based on the morphology of their colonies with physiological and biochemical characteristics. In addition, the characterizations of soil where the presence of these strains were carried out. The total CFU count ranged from 2x106 to 6x106 and total viable bacteria at 32°C ranged from 2.2x103 to 5.6x103 in various soil sample collected in random from contaminated site. The strains had broad degradation capacities and the present remediation monitoring confirmed the effectiveness of Acinetobactor lwoffii has one of the potential native microbes for remediation of crude oil soil.

Prof Isitekhale Henry-Harry E:
The paper is very good as it addresses the remediation of polluted soils. Managing soils for crop production coupled with pollution is quite expensive and require skills. This paper has addressed of the key ways to actualizing the dreams.
