Bioremediation is a highly potential approach to restore and rehabilitate oil polluted soils having many recalcitrant polyaromatic hydrocarbons (PAHs) such as dibenzothiophene (DBT), benzothiophene (BT), etc by use of microorganisms. In the present study biosurfactant producing bacterial diversity and distribution for bioremediation of oil contaminated soils of upper Assam for the growth of Muga host plant Som (Persea bombycina) were studied. Crude oil contaminated soil samples were collected from Lakwa, Gelakey, and Nazira regions of upper Assam and heterotrophic bacteria were isolated. | Diversity and distribution of biosurfactant producing plant growth promoting bacteria PGPB from hydrocarbon contaminated soils of upper Assam
