Abstract
Naval kerosene-based fuels are subject to troublesome growth of fungi, yeasts and bacteria under appropriate environmental conditons. The fungus Cladosporium resinae is generally the dominant micro-organism in fuel, and can produce mats of growth if a fuel-water interface is present. In a survey of fuels from four 280-class destroyers, one supply vessel and one commercial tender, some microbiological contamination (principally Candida sp. and C. resinae) was found in all tanks. Short format biocide trials were conducted on pure cultrues of C. resinae and on mixed cultures derived from sampled tanks, using Omadine, CSW 823, Kathon WT and DGME; results indicate that all biocides gave moderate or good inhibition in pure culture but only Kathon WT gave some inhibition in mixed cultures.
