Summary: | Phenols are poisonous chemical molecules that affect human and other mammals as well as the aquatic environment, particularly higher species in fresh water environments. useing microorganisms through bioremediation is an efficient technique for reducing dangerous chemicals and detoxification of soil contaminated with hydrocarbons. The aim of this study is to investigate the efficiency of some local bacterial species to degrade phenol. Bacterial species were isolated from soils contaminated with hydrocarbons from Al-Diwaniyah and Al-Basrah governorates. The remaining concentration of phenol was examined usingthe 4-aminoantipyrine assay. The results showed that the rate of decomposition of
Enterobacter cloacae
complex was 100% after an incubation period of 120h, pantoea spp was 100% after an incubation period of 120h,
Acinetobacter lwoffii
was 100% after an incubation period of 144h,
Aeromonas salmonicida
was 100% after an incubation period
168h, Escherichia hermannii
was 100% after an incubation period of
168h, Sphingomonas paucimobilis
was 100% after an incubation period of 168h,
Streptococcus thoraltensis
was 100% after an incubation period of
168h, Bacillus licheniformis
was 97.98%after an incubation period of 168h,
Bacillus subtilis
was 95.91% after an incubation period of 168h, and
Bacillus firmus
was 70.91% after an incubation period of 168h. The tested bacterial strains can offer a potential basis for bioremediation of phenol polluted locations. |
