Description

DESCRIPTIONOF LACTICASEIBACILLUS GEN. NOV.

Lacticaseibacillus (Lac.ti.ca.se.i.ba.cil'lus. L. neut. n. lac milk; L. n. caseus cheese, referring to the casei-group lactobacilli; L. masc. n. bacillus a rod; N.L. masc. n. Lacticaseibacillus a milk-derived rodlet from the [Lactobacillus] casei group).

Strains of Lacticaseibacillus are homofermentative; some but not all species metabolise pentoses via the phosphoketolase pathway. The mol % G+C content of DNA is between 46 and 58.0. The genome size ranges from 1.93 to 3.14 Mbp. Strains are non-motile, oxidase negative, often producing D(−)- and L(+)-lactic acid from glucose. The temperature range for growth is variable, but never below 10 °C and never above 45 °C. One subspecies survives 70 °C for 40 s. Lys–D-Asp is the most common type of the peptidoglycan. The genus has considerable economic importance as it harbours several species thatare used as starter cultures indairy fermentations and as probiotics [58, 59].

Aphylogenetic tree on the basis of 16S rRNA genes of all species in the genus Lacticaseibacillus is provided in Fig. S6F.

The type species is Lacticaseibacillus casei comb. nov.; Lacticaseibacillus was previously referred to as L. casei group.
