description
Aphylogenetic tree on the basis of 16 S rRNA genes of all species in thegenus Fructilactobacillus is provided in Fig. S 6 Q. The typespecies of the genus is Fructilactobacillusfructivorans comb. nov.; Fructilactobacillus was previously referred to as L. fructivorans group.
discussion
Fructilactobacillus (Fruc. ti. lac. to. ba. cil’lus. L. masc. n. fructus, fruit; N. L. masc. n. Lactobacillus a bacterial genus name; N. L. masc. n. Fructilactobacillus, fruit-loving lactobacillus, referring to the preference for growth in presence of fructose as electron acceptor). Gram-positive, rod-shaped, catalase negative, heterofermentative and aerotolerant. Growth is observed at 15 ° C but not at 37 ° C. Strains in thegenus have very small genomes ranging from 1.23 Mbp for Fructilactobacillus sanfranciscensis to 1.44 Mbp for Fructilactobacillus lindneri; the mol % G + C content of DNA as calculated from whole genome shotgun sequences ranges from 34.1 to 38.9. Comparable to other insect-associated lactobacilli, strains in the genus ferment only few carbohydrates; some strains ferment only maltose and sucrose. Most strains of the species are fructophilic and use fructoseas electron acceptor ratherthan as carbon source. Several species in the genus are core member of insect intestinal microbiota, and were isolated from insects, flowers, and spoiled or fermented foods.
