英文摘要: In the present study a metabolically versatile co-culture with two Bacilli and one yeast strain was developed using enrichment culture techniques. The developed co-culture had affinity to degrade both aliphatic and aromatic fractions of petroleum crude oil. Degradation kinetics was established for designing the fermentation protocol of the co-culture. The developed mass culture strategy led to achieve the reduction in surface tension (26 dynes cm- 1 from 69 dynes cm- 1) and degradation of 67% in bench scale experiments. The total crude oil degradation of 96% was achieved in 4000 l of natural seawater after 28 days without adding any nutrients. The survival of the augmented co-culture was maintained (109 cells ml- 1) in contaminated marine environment. The mass culture protocol devised for the bioaugmentation was a key breakthrough that was subsequently used for pilot scale studies with 100 l and 4000 l of natural seawater for potential application in marine oil spills. © 2015 Elsevier Ltd.
