aData from Grabovich et al. (2021), Gridneva et al. (2011), and Spring et al. (1996)
b+ Positive or supported growth;− negative or did not support growth; ± sheath formation was easily lost during maintenance
cNot determined
dNo genomic data is available for L. cholodnii LMG 7171 T
eBased on genome-wide sequences other than L. cholodnii LMG 7171 T, which (mol%) was determined by the thermal denaturation method (Spring et al. 1996)
