Composition of the bacterial community in food waste samples from (a) the hydropulper and (b) digestor feed determined with Illumina sequencing. Genus-level identities are presented where possible. Relative abundance excludes chloroplast entries (< 25%). The variation in the abundance of Lactobacillaceae in the bacterial community includes only Lactobacillaceae lineages with > 1% relative abundance (Lin1-7). Minor Lactobacillaceae include all Lactobacillaceae lineages with less than 1% relative abundance. Lin 1–3 on the graphs correspond to Lactobacillus/Lactiplantibacillus Lin1-3 in the legend. (c) Maximum likelihood phylogenetic tree of Family Lactobacillaceae extracted from the Illumina 16S rRNA Illumina sequence entries (Lin1-7 indicated by solid circle). Number and scale in figure showing the phylogenetic relationship between bacterial lineages observed in food waste and their closest cultured relatives. Numbers represent bootstrap (branch point confidence) values from 500 replicates.
