Experiments were designed to evaluate the nature and extent of microbial contamination and the potential for microbiologically influenced corrosion in biodiesel (B100), ultra-low sulfur diesel (ULSD) and mixtures of the two (B5 and B20). In experiments with additions of distilled water, B100 had the highest propensity for biofouling while the highest corrosion rates were measured in ultra-low-sulfur diesel.
