Different superscript uppercase letters within loading components indicate significant differences (p < 0.05) between the six combinations of total log concentration by 1 and 3 assortments (Two-way ANOVA with Tukey test). When there was no effect from total log concentration (see Table 3), data within 1 and 3 assortments were pooled. Different superscript lowercase letters within rows indicate significant differences (p < 0.05) (One-way ANOVA with Tukey test).
