A select number of aerobic bacterial and fungal cultures isolates from contaminated fuel tank bottoms were screened against a variety of jet fuels JP-4 and JP-6, a lubricant, a liquid rocket propellant, and a spectrum of pure hydrocarbons naphthenes and normal and branched alkanes for growth-supporting properties. Variable growth support on all jet fuel samples was noted with the exception of one which was found to contain no detectable normal alkanes. Removal of normal alkanes from the other jet fuel samples significantly reduced their growth-supporting properties. The normal alkanes supported the most growth, the 2-methyl and 2,2-dimethyl alkanes lesser growth, and the naphthenes no growth support. After the prolonged incubation of several of the bacterial cultures on the initially resistant jet fuel sample, several cultures adapted to it. A variety of jet fuel additives were also screened against bacterial cultures and certain types were found to inhibit growth. Author
