Anaerobic degradation of crude oil by sulphate reducing bacteria isolated from soils contaminated with petroleum hydrocarbons
This study included isolatation a mix cultures of sulphate reducing bacteria from soils in Shaeba regain contaminated with petroleum hydrocarbons by using API medium enriched with oxygen reducing agents and saturated with gas (90% N2 ) and ( 10% CO2 ) by using sodium lactate as sole carbon source.

| description | This study included isolatation a mix cultures of sulphate reducing
bacteria from soils in Shaeba regain contaminated with petroleum hydrocarbons by using API
medium enriched with oxygen reducing agents and saturated with gas (90% N2 ) and
( 10% CO2 ) by using sodium lactate as sole
carbon source. The result showed that the number of bacteria ranged
( 4 x 105 – 4.5 x 105 ) cells / g of soil. Also using crude oil as a sole of
carbon source to study the ability of sulphate reducing bacteria on
degradation of crude oil under anaerobic condition . The result showed
these bacteria have high ability for degradation of crude oil. The percent
rate of degradation in culture was ( 84.4 % ) after (54) days incubation
and the rate concentration of total petroleum hydrocarbons ( TPH )
extraction from culture value ( 22.06 ) ?g / L , while in control was
( 190.84 ) ?g / L. |
