DESCRIPTIONOF BOMBILACTOBACILLUS GEN. NOV.

Bombilactobacillus (Bom.bi.lac.to.ba.cil’lus. L. masc. n. bombus, buzzing of beesand bumblebees, N.L. masc. n. Lactobacillus a bacterial genus; N.L. masc. n. Bombilactobacillus , a lactobacillus from bees and bumble bees).

Bombilactobacillus species have been isolated from the stomach and the hindgut of honey bees ( Apis mellifera ) and bumble bees where they are associated with the heterofermentative sister genus Apilactobacillus . Bombilactobacillus species have genome sizeswhich rangefrom 1.81 to 1.84 Mbp anda mol% G+C content ranging from 34.7 to 39.5. They are homofermentative and thermophilic; comparableto other insect-associated lactobacilli, bombilactobacilli ferment only a narrow spectrum of carbohydrates.

Aphylogenetic tree on the basis of 16S rRNA genes of all species in the genus Bombilactobacillus is provided in Fig. S6B .

The type species is Bombilactobacillus mellifer comb. nov; Bombilactobacillus was previously referred to as L. mellifer group.

Figures

Fig. 6. Gene family presence/absence patterns in Lactobacillaceae and Leuconostocaceae. Each column represents a gene family presence/absence pattern in species of Lactobacillaceae and Leuconostoaceae, where presence is indicated with a dot. The absolute number of gene families that conform to each pattern is visualized in the marginal bar plot at the top. Separations between phylogroups are indicated with horizontal black lines. We defined genes that were present in all genomes of a clade and in none of the genomes outside of that clade as ‘signature genes’ (dark blue); other genes are shown in light blue. Only presence/absence patterns followed by four or more gene families are shown. Patterns of presence in a single species or all species are not shown. Unassigned species are clusters of closely related genomes which could not be assigned to a known species due to low whole-genome similarity to a type strain and/or low 16S rRNA similarity to a type strain.
