An aerobic, Gram-stain-negative, rod-shaped bacterium (strain CC-ALB-1T) was isolated from the rhizosphere of Arabidopsis thaliana. Strain CC-ALB-1T was able to grow at 20–30 °C, pH 5.0–8.0 and with up to 1.0 % (w/v) NaCl. 16S rRNA gene sequence analysis showed that strain CC-ALB-1T had the highest sequence similarity to Chitinophaga ginsengisegetis Gsoil 040T (96.9 %) and Chitinophaga niastensis JS16-4T (96.7 %); lower levels of similarity (<97.0 %) were observed to strains of all other species of the genus Chitinophaga . The fatty acid profile consisted of iso-C15 : 0, iso-C17 : 0 3-OH, C15 : 1ω5c, C16 : 1ω5c and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The polar lipid profile contained phosphatidylethanolamine, two unidentified aminolipids and five unidentified lipids. The predominant quinone system was menaquinone 7 (MK-7). The DNA G+C content was 53.4±0.4 mol%. Based on its phylogenetic, phenotypic and chemotaxonomic features, strain CC-ALB-1T is proposed to represent a novel species within the genus Chitinophaga , for which the name Chitinophaga taiwanensis sp. nov. is proposed. The type strain is CC-ALB-1T ( = BCRC 80570T = JCM 18895T).

Strains of the recently proposed species Bacteroides chinchillae share more than 99.4 % 16S rRNA gene sequence similarity with the type strain of Bacteroides sartorii although these two species do not appear to be similar from their published descriptions. The aim of this study was to perform phenotypic and genetic analyses of both species to clarify their taxonomic position. B. chinchillae JCM 16497T exhibited high hsp60 gene sequence similarity with B. sartorii JCM 17136T (100 %) as well as B. chinchillae JCM 16498 (100 %). The hsp60 gene sequence analysis and levels of DNA–DNA relatedness observed demonstrated B. sartorii JCM 17136T, B. chinchillae JCM 16497T, and B. chinchillae JCM 16498 are members of a single species. Based on these data, we propose Bacteroides chinchillae as a later heterotypic synonym of Bacteroides sartorii . An emended description of B. sartorii is provided.

Five strains, JPY461T, JPY359, JPY389, DPU-3 and STM4206 were isolated from nitrogen-fixing nodules on the roots of Mimosa spp. and their taxonomic positions were investigated using a polyphasic approach. All five strains grew at 15–40 °C (optimum, 30–37 °C), at pH 4.0–8.0 (optimum, pH 6.0–7.0) and with 0–1 % (w/v) NaCl [optimum, 0 % (w/v)]. On the basis of 16S rRNA gene sequence analysis, a representative strain (JPY461T) showed 97.2 % sequence similarity to the closest related species Burkholderia acidipaludis SA33T, a similarity of 97.2 % to Burkholderia terrae KMY02T, 97.1 % to Burkholderia phymatum STM815T and 97.1 % to Burkholderia hospita LMG 20598T. The predominant fatty acids of the five novel strains were summed feature 2 (comprising C16 : 1 iso I and/or C14 : 0 3-OH), summed feature 3 (comprising C16 : 1 ω7c and/or C16 : 1 ω6c), C16 : 0 , C16 : 0 3-OH, C17 : 0 cyclo, C18 : 1 ω7c and C19 : 0 cyclo ω8c. The major isoprenoid quinone was Q-8 and the DNA G+C content of the strains was 63.0–65.0 mol%. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unidentified aminophospholipid, an unidentified aminolipid and several unidentified phospholipids. The DNA–DNA relatedness of the novel strain with respect to recognized species of the genus Burkholderia was less than 54 %. On the basis of 16S rRNA and recA gene sequence similarities, chemotaxonomic and phenotypic data, the five strains represent a novel species in the genus Burkholderia , for which the name Burkholderia diazotrophica sp. nov. is proposed with the type strain, JPY461T ( = LMG 26031T = BCRC 80259T = KCTC 23308T).
