The sample codes are as described in Table 1. ASVs with an occurrence under 0.1 % were grouped as “Others.” The following abbreviations are used: Fl., Fructilactobacillus; Ff., Furfurilactobacillus; Lacc., Lacticaseibacillus; Lacp., Lactiplantibacillus; Latl., Latilactobacillus; Lenl., Lentilactobacillus; Levl., Levilactobacillus; Loil., Loigolactobacillus; P., Pediococcus; A., Acetobacter; G., Gluconobacter. The intensity of the blue color is based on the percentage of reads assigned to a specific species/genus.
