Means with a different letter(s) in the same column differed significantly (p < 0.05) according to the DMRT test. Data were square-root transformed prior to ANOVA; the reported are untransformed means. Viable counts were estimated from three replicate spread-plates and expressed as CFU/10 g substrate for each strain sampled ± standard deviation.
