DESCRIPTIONOF SECUNDILACTOBACILLUS GEN. NOV.

Secundilactobacillus (Se.cun.di.lac.to.ba.cil’lus. L. adj. secundus, second or next, following; N.L. masc. n. Lactobacillus a bacterial genus name; N.L. masc. n. Secundilactobacillus a lactobacillus that occurs in a secondary fermentation or as a spoilage organism after primary fermenters depleted hexoses and disaccharides).

Gram-positive, rod-shaped, catalase negative, heterofermentative. Most strains grow at 15 °C and some also grow at 45 °C, the pH range of growth ishighly variable. The genome size ranges from 1.85 Mbp for S. oryzae to 3.62 Mbp for S. collinoides , the mol% G+C content of DNA ranges from 41.03–47 %. Strains in the genus lead a free-living lifestyle and were isolated as secondary fermentation or spoilage organisms from hexose-depleted habitats including silage, beer, liquor mashesand apple cider. Metabolic propertiesof Secundilactobacillus species match adaptation to hexose-depleted habitats. Manystrains of thegenus do not reduce fructose to mannitol, a traitwhich differentiates Secundilactobacillus fromall other heterofermentative lactobacilli except Paucilactobacillus . Many strainsinthe genus metabolize diolsvia diol-hydratase and convert agmatine, a metabolite of arginine decarboxylation, via the agmatinedeiminase pathway. Strains in the genus generally harbour genes coding for transaldolase/transketolase which mediate metabolism of pentoses to pyruvate.

Aphylogenetic tree on the basis of 16S rRNA genes of all species in the genus Secundilactobacillus is provided in Fig. S6O View Fig .

The type species of the genus is Secundilactobacillus malefermentans comb. nov.; Secundilactobacillus was previously referred to as the Lactobacillus collinoides group.
