Figure 1.
Changes in the copy number (log10 copies/g DM) of (a) Saccharomyces cerevisiae and (b) Lactobacillus buchneri in whole-crop corn silage during both ensiling and aerobic exposure as quantified by qPCR. Control = uninoculated; S4 = S. cerevisiae (1 × 104 cfu/g wet silage); S5 = S. cerevisiae (1 × 105 cfu/g wet silage); S4L5 = S. cerevisiae (1 × 104 cfu/g wet silage) and Lactobacillus buchneri (1 × 105 cfu/g wet silage); S5L4 = S. cerevisiae (1 × 105 cfu/g wet silage) and L. buchneri (1 × 104 cfu/g wet silage). Treatments with different letters within each sampling day in (a) differ at P < 0.05. No letters in (b) indicate that L. buchneri did not exhibit a significant treatment × sampling day interaction.
