Currently many large areas are present in Assam which is contaminated with petroleum and diverse petroleum constituents. Crude oil is a composite mixture of hundreds of hydrocarbons. Out of hundreds of different hydrocarbon molecules, mainly aliphatic hydrocarbons (also known as paraffins) from C1 to C40 straight chain, C6–C8 branched-chain, cyclohexanes, aromatics compounds (Stafford et al., 1982) are present in crude oil. An investigation was conducted to study the efficiency of two bacterial strains Cellulosimicrobium sp. Strain 26ML and Bravibacillus laterosporus strain 3SG in degradation of aliphatic hydrocarbons viz n-heptane, n-dodecane and n-hexadecane (purity 99%). Comparative study on ability of growth of the two strains was evaluated in LMM (Liquid Mineral Media) supplemented with 200ppm (v/v) of the respective hydrocarbons using CFU method,UV spectrophotometer, estimating cell biomass and GC analysis up to a period of 240h. | | Keywords : | | |
