FIG 4.

Microbial community dynamics of laboratory carrot juice fermentation LF3. (A) Microbial counts on MRS agar for presumptive LAB, VRBG agar for presumptive Enterobacteriaceae, and YPD agar for presumptive yeasts. (B) Taxonomic profiling based on both DNA and RNA, followed by amplicon sequencing of the V4 region of the 16S rRNA gene. Only the top 20 amplicon sequence variants are shown, and they are colored by their highest unclassified rank. The sample time points are shown with a dashed line. (C) Read distribution of bacterial and nonbacterial sequences after quality control of DNA-based and RNA-based 16S rRNA gene sequencing of the V4 region.
