  • a Only OTUs with an incidence above 1% in at least 2 samples are shown. Values are expressed as the mean of duplicate determinations. The abundances of OTUs in the 2 biological replicates of each sampling time were averaged. Samples are labeled according to the fermentation period (0 h [T0], 48 h [T48], 96 h [T96], and 120 h [T120]), fermentation method (box and heap), and condition (inoculated with S, inoculated with ST, and noninoculated).
