Fuel-soluble biocides for control of Cladosporium resinae in hydrocarbon fuels

Abstract

Five fuel-soluble biocides - a benzimidazole fungicide, an organoboron, a pyridinethione and two isothiazolone products - were evaluated for inhibition of a typical hydrocarbon fuel contaminant, Cladosporium resinae, in fuel/water systems. The biocides exhibited marked differences in anti-fungal activity with storage and in the presence of sludge. A methylchloro/methyl-isothiazolone mixture prevented growth of the fungus at a concentration of one part per million and, in contrast to other biocides tested, showed no tendency to be inactivated by storage or the presence of sludge. © 1987 Society for Industrial Microbiology.
