Jet and diesel fuels are readily infested by microorganisms. Mycobacteria, pseudomonads, the fungusCladosporium resinae, and certain other microorganisms grow well at the expense of the hydrocarbons of these fuels. Anaerobic sulfate-reducing bacteria grow only after these aerobic forms, probably at the expense of the latter's metabolites. B-70 gasoline is more resistant to microbial infestation; only bacteria of the Pseudomonas genus grow in this fuel.

A study has been made of the antibacterial action of certain additives in B-70 gasoline and TS-1 fuel. Dimethyldialkylammonium chloride and dimethylalkylbenzylammonium chloride proved to be most effective additives, suppressing the growth of all microorganisms in the test fuels when used at concentrations of 0.05–0.25%.

Compound additives, bactericidal and antistatic, have been prepared on the basis of antistatic agents (chromium oleate, chromium dioleate of ferrocene  -diketone, chromium dioleate of manganese cyclopentadienyl tricarbonyl -diketone, and others) and bactericides (dimethyldialkylammonium chloride and dimethylalkylbenzyl-ammonium chloride). These additives suppress the growth of microorganisms in fuels and also give the fuel antistatic properties.
