FIG 3.

Taxonomic composition based on 16S rRNA gene sequencing (V4 region) of laboratory fermentations 1 (LF1) and 2 (LF2) and of the household fermentations (HF). The relative abundances of all amplicon sequence variants belonging to the same genus were summed, and only the 12 most abundant genera are shown. Relative abundances belonging to the same fermentation are connected with a gray line. The numbers above each box plot represent the number of fermentations in which this genus was detected.
