Routine washing, cleaning, repairing, maintenance of cars, bikes, scooters and disposal of waste of all kinds are carried out in automobile workshops are common observations in Aligarh. Considering the likelihood of existence of biosurfactant producing organisms at hydrocarbon contaminated site, a large number of soil samples were collected and isolation was carried out. A total of ten bacterial strains ALIG (01–10) were isolated out of which only isolate АLIG01 grown on GSP agar, Maconkey agar as well as on Pseudomonas agar plates which indicated suspected Pseudomonas spp. and exhibits positive biosurfactant activity through penetration assay, oil spreading technique, beta hemolytic activity and ЕI24 (96%), positive blue plate agar plate (> 2сm), qualatitative analysis, tolerance against hydrocarbon m-xylene, and microplate assay. This isolate АLIG01 is a valuable source to investigate further for future agriculture plant pathology and industrial applications.
