Temporal distribution of butyrate producers in the fermented grains of Luzhou-flavor baijiu. (A) Taxonomic distribution and enzymes (ptb, buk, atoD, atoA and ACSM) reads for butyrate formation in the microbial community of fermented grains via PICRUSt analysis. The diameters of bubbles (scale) are proportional to the read numbers of enzymes. (B) Succession of three major classes (Clostridia, Bacilli, and Bacteroidia) related to butyrate synthesis based on sequencing of 16S rRNA gene. (C) Family-level diversity of buk-associated Bacilli in the fermented grains on day 0. The numbers represent the read numbers of buk. (D) Family-level diversity of buk-associated Bacteroidia in the fermented grains on day 7. The numbers represent the read numbers of buk.
