Abstract

Two bacterial strains, FWR-8 and CFWR-9, were isolated from the gut of larvae of that were raised at the National Institute of Agricultural Sciences, Wanju-gun, Republic of Korea. Both strains were strictly aerobic, Gram-stain-positive and non-motile. Strain FWR-8 possessed the highest sequence similarity (98.7 %) to that of 2DFWR-13 and the phylogenetic tree revealed that strain FWR-8 formed a cluster with 2DFWR-13. MSL-13 and N7XX-4 shared a high 16S rRNA gene sequence similarity (97.8 %) and formed a cluster adjacent to the cluster that included 2DFWR-13. The 16S rRNA gene sequence of strain CFWR-9 exhibited the highest similarity (97.7 %) to that of OAct353 and the phylogenetic tree indicated that strain CFWR-9 formed one independent cluster with OAct353 that was within the radius of the genus . The peptidoglycan type, major fatty acids, major menaquinones and total polar lipids of strain FWR-8 were characterized as type B1, iso-C, anteiso-C and anteiso-C, MK-15, MK-16 and MK-14, and diphosphatidylglycerol, phosphatidylglycerol, two unidentified glycolipids and one unidentified lipid, respectively. Those from strain CFWR-9 were type B1, iso-C, anteiso-C and anteiso-C, MK-11, MK-12 and MK-10, and diphosphatidylglycerol, phosphatidylglycerol, two unidentified glycolipids and one unidentified lipid, respectively. Based on the phenotypic and genotypic data, strains FWR-8 and CFWR-9 each represent a novel species within the genera and , respectively. For these species, the names sp. nov. and sp. nov. have been proposed, with the type strains FWR-8 (=KACC 19322=NBRC 113051) and CFWR-9 (=KACC 19306=NBRC 113046), respectively. Our results also justify a reclassification of as comb. nov. and an emended description of the genus isprovided.
