DESCRIPTION OF LENTILACTOBACILLUS SENIORIS COMB. NOV.

Lentilactobacillus senioris (se.ni.o’ris. L. gen. n. senioris of an elderly person, indicating the source of the type strain).

Basonym: Lactobacillus senioris Oki et al., 2012 , 606 VP

Growth is observed at 15 and 37 °C but not at 45 °C; the type strain was isolated from human faeces [ 173]. L. senioris is the most distantly related member of the genus, has the smallest genome size (1.57 Mbp) and lowest G+C content (39.9) among species in the genus, and does not share the signature genes that are shared by other lentilactobacilli, which may indicate that L. senioris transitions from a free-living to a host-adapted lifestyle.

Isolated from from the faeces of a 100-year-old female.

The type strain is YIT 12364 T = DSM 24302 T = JCM 17472 T .

Genome sequence accession number: AYZR00000000.

16S rRNA gene accession number: AB602570 .
