Abstract
Laboratory-Scale Trials were carried out to investigate specific factors having an impact on growth of potential Microbiological Contamination (MBC) in Naval Distillate fuel. Bottle-Scale Efficacy Trials using 95% fuel overlaying 5% supplemented synthetic seawater confirmed that, of the six biocides evaluated, Omadine TBAO, Kathon WT and Fuel Saver produced the greatest inhibition of growth (measured as protein production) of pure cultures of Cladosporium resinae, Yarrowia lipolytical and Penicillium sp. whereas Biobor JF, D.G.M.E. and Benomyl showed variable effects. Mixtures of the fungus C. resinae, the yeast Y. lipolytica and the bacteria Pseudomonas aeruginosa were resistant to all biocides tested, except for Omadine TBAO, which demonstrated minor inhibition.
