DESCRIPTION OF LAPIDILACTOBACILLUS GEN. NOV.

Lapidilactobacillus [La.pi.di.lac.to.ba.cil’lus L. masc. n. lapis, stone, referring to the isolation source of the type species Lapidilactobacillus concavus ; N.L. masc. n. Lactobacillus a bacterial genus; N.L. masc. n. Lapidilactobacillus , a lactobacillus isolated from stone (walls)].

The cells are Gram-positive rods or cocci, homofermentative, non motile, non-spore-forming, facultatively anaerobes, and catalase-negative. Pentose utilization and the pH range for growth are strain dependent, the optimum pH is between 6.0 and 7.0. They are homofermentative and mainly produce L-lactic acid. The optimum temperature for growth is 30–37 °C. No ammonia is produced from arginine. The mol% G+C content of DNA is between 38.1 and 49.0.

A phylogenetic tree on the basis of 16S rRNA genes of all species in the genus Lapidiactobacillus is provided in Fig. S6D .

The type species is Lapidilactobacillus concavus comb. nov.; Lapidilactobacillus was previously referred to as L. concavus / dextrinicus 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.
