In environmental biotechnology, evaluation of microbial communities relevant to their genetics and ecological perspectives has significant concern. Microorganisms, when exposed to unusual factors in their micro environment, become able to adapt these unusual factors or components by manipulating the specific genes and metabolic pathways. Environment polluted with hydrocarbons, allows bacteria to enhance their metabolic capabilities by horizontal/vertical gene transfer, mutation and adaptation to ecological stresses. So, this property of microorganisms can be employed to make pollutant-free environment. The basis of this research is bioremediation of hydrocarbons in contaminated soil. For this purpose, quantitative analysis was carried out in order to examine the potential of isolated Bacillus species for hydrocarbon consumption. Among all strains, HRA-1 and HRA-4 exhibited hydrocarbon absorption ability. Isolate HRA-5 displayed xylene degradation while HRA-1 took up benzene efficiently. This study explores the importance of hydrocarbon utilizing bacteria (HUB) that could be suggested for bioremediation purposes.
