A Gram-reaction-negative, strictly aerobic, yellow-pigmented, rod-shaped bacterium, designated strain T3T, was isolated from freshwater of Chishui River flowing through Maotai town, Guizhou, south-west China. Analysis of the16S rRNA gene sequence indicated that strain T3T was a member of the genus Flavobacterium and closely related to Flavobacterium resistens DSM 19382T (96.8  %). The novel strain was able to grow at 10–34 °C (optimum 28 °C), pH 6.0–11.0 (optimum pH 8.0–9.0) and with 0–2.0  % (w/v) NaCl (optimum 0  %). The major polar lipids were phosphatidylethanolamine, two unknown glycolipids, five unknown aminolipids and four unidentified lipids, and the major respiratory quinone was MK-6. The predominant fatty acids were C16  :  1ω7c and/or C16  :  1ω6c and iso-C15  :  0. The DNA G+C content of the strain was 36 mol  %. Based on these data, strain T3T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium procerum sp. nov. is proposed. The type strain is T3T ( = CGMCC 1.12926T = JCM 30113T).

A novel bacterial strain, designated M2T2B15T, was isolated from fermented bovine products and was characterized by using a polyphasic approach. Colonies were reddish pink and circular with entire margins. Cells were strictly aerobic, Gram-reaction-negative, oxidase- and catalase-positive rods that lacked flagella and were motile by gliding. Flexirubin-type pigments were absent. 16S rRNA gene sequence analysis indicated that strain M2T2B15T was related most closely to Larkinella insperata LMG 22510T (94.4 % similarity) but shared <87 % similarity with other members of the phylum Bacteroidetes. The major cellular fatty acids were C16 : 1 ω5c, iso-C15 : 0 and iso-C17 : 0 3-OH. The polar lipids were phosphatidylethanolamine, phosphatidylserine, two unidentified aminophospholipids and two unidentified polar lipids. Menaquinone 7 (MK-7) was the major respiratory quinone. The G+C content of the DNA of strain M2T2B15T was 52 mol%. The phenotypic, genotypic and phylogenetic data presented clearly indicate that strain M2T2B15T represents a novel species of the genus Larkinella, for which the name Larkinella bovis sp. nov. is proposed. The type strain is M2T2B15T (=KACC 14040T =NBRC 106324T). Emended descriptions of the genus Larkinella and of Larkinella insperata Vancanneyt et al. 2006 are also proposed.

A Gram-negative, strictly aerobic, rod-shaped, non-motile, non-spore-forming bacterial strain, designated TR6-04T, was isolated from compost and characterized taxonomically by using a polyphasic approach. The organism grew optimally at 30 °C and at pH 6.5–7.0. The isolate was positive for catalase and oxidase tests but negative for gelatinase, indole and H2S production. Comparative 16S rRNA gene sequence analysis showed that strain TR6-04T fell within the radiation of the cluster comprising Sphingobacterium species and clustered with Sphingobacterium mizutaii ATCC 33299T (96.7 % sequence similarity); the similarity to sequences of other species within the family Sphingobacteriaceae was less than 92.0 %. The G+C content of the genomic DNA was 38.7 mol%. The predominant respiratory quinone was MK-7. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 4 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c). These chemotaxonomic data supported the affiliation of strain TR6-04T to the genus Sphingobacterium. However, on the basis of its phenotypic properties and phylogenetic distinctiveness, strain TR6-04T (=KCTC 12579T=LMG 23402T=CCUG 52468T) should be classified as the type strain of a novel species, for which the name Sphingobacterium daejeonense sp. nov. is proposed.
