gen. nov., sp. nov. and sp. nov. isolated from fresh flowers of durian tree and hibiscus Free

Abstract

Three strains of Gram-staining-positive, coccus-shaped, lactic acid bacteria, designated as HibF3, HibF2 and HibF5 were isolated from fresh flowers of hibiscus, and a fourth, DF1, was isolated from fresh flowers of durian tree, in Penang, Malaysia. Taxonomic characterisation was performed by polyphasic analysis. Sequence similarities of the 16S rRNA gene and the housekeeping and genes of these strains with their closely-related lactococcal and streptococcal relatives were 92–94, 78 and 81 %, respectively. The results of phylogenetic analysis indicated that strains DF1, HibF2, HibF5 and HibF3 were clustered together but were clearly separated from species of the genera and , indicating that they represent members of a novel genus of the family . Calculation of average nucleotide identity (ANI) values between the genomes of DF1 and HibF3 yielded values of 92.50–92.93 %. ANI values below the cut-off value and distinctive chemotaxonomic characteristics supported the hypothesis that these strains represented two novel species. Major cellular fatty acids in DF1, HibF2 and HibF5 were Cω7 and C, while C and C were also dominant, in addition to Cω7 and C, in HibF3. A novel genus is proposed with the name gen. nov. which consists of two species, sp. nov as the type species, and sp. nov. The respective type strains are DF1 (=LMG 29833=JCM 31733) and HibF3 (=LMG 29831=DSM 31735).
