Abstract:
A bacterial community able to degrade cis- and trans-decalin (decahydronaphthalene) in the presence of n-decane could be isolated. It was composed by a couple of Pseudomonas strains (D1 and D2, respectively). Neither the community nor the isolated strains were able to grow on decalin alone. D1 grew on decalin plus n-decane. Both could grow on n-decyl alcohol, acetate and adipate. From hydrocarbonated substrates it would be generated a metabolic chain which allows the growth of the community members, and then it resulted to be stable. Characteristics of both strains are described.
