DESCRIPTION OF LATILACTOBACILLUS GEN. NOV.

Latilactobacillus (La.ti.lac.to.ba.cil'lus. L. masc. adj. latus wide, broad; N.L. masc. n. Lactobacillus a bacterial genus name; N.L. masc. n. Latilactobacillus a widespread lactobacillus).

Species of Latilactobacillus are homofermentative, their mol% G+C content is between 40 and 42 and the genome size ranges from 1.82 to 2.12 Mbp; they produce both D(−)- and L-(+)- lactic acid with the exception of L. fuchuensis , which produces only the L(+)- isomer. Strains in the species lead a free-living lifestyle and are mesophilic; many strains are psychrotrophic and grow below 8 °C. L. sakei and L. curvatus have commercial importance as meat starter cultures [ 58, 59].

A phylogenetic tree on the basis of 16S rRNA genes of all species in the genus Latilactobacillus is provided in Fig. S6G .

The type species is Latilactobacillus sakei comb. nov.; Latilactobacillus was previously referred to as L. sakei 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.
