Abstract

Control of microbial activity in fuel may require the use of chemical biocides. In their evaluation in distillate fuels, a number of variables must be considered. These include the oil/water ratio, the biocide's partition coefficient, the stability of the biocide, the longevity of contamination, the presence of other nonbiocidal additives, and the microbiological spectrum (including specific recovery methods for these microorganisms). This paper will present data dealing especially with test method development, taking into account the above permutations.
