description
Aphylogenetic tree on the basis of 16 S rRNA genes of all species in the genus Secundilactobacillus is provided in Fig. S 6 O. The type species of the genus is Secundilactobacillus malefermentans comb. nov.; Secundilactobacillus was previously referred to as the Lactobacillus collinoides group.
discussion
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.
