Polycyclic aromatic hydrocarbons (PAHs) are the pollutants having ubiquitous distribution in the surroundings derived from both anthropogenic and natural resources. PAHs biodegradation has been receiving constant scientific consideration. Highly potential, PAHs degrading bacteria were isolated and idendified from crude oil contaminated sludge enriched with naphthalene. Among the isolates Bacillus foraminis is an aerobic, Gram positive, alkaliphilic. The present study was report for bacterial isolates Bacillus foraminis utilizing the PAHs (naphthalene, and anthracene,) as sole carbon and energy source. The PAHs degradation study were conducted in liquid medium, with the different substrate concentration of naphthalene (100 ,200 and 300mg l-1) and anthracene (50,100 and 150 mg l-1) .The results revealed that the bacteria degraded naphthalene completely 96.66±0.018% at120 h, and anthracene 99.07 ± 0.449 % at144 h for the substrate concentration (100 and 50 mg L-1) . From the outcomes, the biodegradation potential of Bacillus foraminis isolated from the polluted sludge should be examined and Various factors optimized for bioremediation purpose.
