Abstract :
Using Environmental-friendly methods in order to remove or reduce oil pollutants and
their derivations in the environment are developing. In this study, the biodegrading ability ofBacillus
Subtilis .sp which has been separated from oil-polluted soil was examined. It was revealed that it can
reduce surface tension of growth Medium and produce Bio-Surfactant at 37 and 20 Degrees
centigrade. Also, it has the ability to biodegrade oil hydrocarbons. A reduction in surface tension
from 58 Nm/m to 31.2 Nm/m at different percentages of crude oil at 37 degrees centigrade is one of the
important results.
