Isolation and characterization of crude oil degrading bacteria from the Persian Gulf (Khorramshahr provenance).
Fifteen crude oil degrading bacteria were isolated from oil contaminated sites in the Persian Gulf at Khorramshahr provenance. These bacteria were screened with two important factors such as growth rate on crude oil and hydrocarbon biodegradation, and then three strains were selected from 15 isolated strains for further study. One strain (PG-Z) that show the best crude oil biodegradation was selected between all isolates. Nucleotides sequencing of the gene encoding for 16S rRNA show that strain PG-Z belong to Corynebacterium variabile genus. This strain was efficient in degrading of crude oil. This strain was capable to degraded 82% of crude-oil after one week incubation in ONR7a medium. The PG-Z strain had high emulsification activity and biosurfactant production between all isolates. GC-MS analysis shows that C. variabile strain PG-Z can degrade different alkanes in crude oil.
