Abstract: The most common problems today are caused due to petroleum products, their use and their degradation. If exposed to the environment they can be hazardous to the surroundings as well as life forms. Thus remediation of these is of utmost importance. Bioremediation is a non-invasive and cost effective technique for the clean-up of these petroleum hydrocarbons. The present study was investigated to evaluate the ability of microorganisms present in the soil itself to degrade these hydrocarbons so that contaminated soils can be treated using microbial consortium. Soil from areas near garages is used to isolate the microorganism which is further used to create an inoculum, whose ability to degrade heavy as well as light crude oil is assessed quantitatively. The bacterial species C3 and D2 showing maximum degradation of petroleum (37.55% and 45%) were identified based on Bergey’s manual and was tentatively identified as Bacillus subtilis and Bacillus megaterium for the samples from Civil lines and Dandi respectively
