Notes:
Fungi and bacteria taken from fuel systems were allowed to grow in jet fuel (or hydrocarbon)-salt solution mixtures and the layers were analyzed for surfactant properties. The fuels included both JP-4 and JP-5 types and an alkylate bottom fraction. Controlled surface activity was imparted to some samples by adding minute quantities of either petroleum sulfonates or petroleum naphthenates. Analyses after growth periods of 2 to 14 weeks failed to show any significant increases in the surface active properties of any fuel or hydrocarbon sample. In all cases, there was either little change or else the surfactant effect was reduced slightly. Opposed to these findings, examination of the aqueous bottoms revealed that microbial growths did effect increases in their surface active properties.
