A bacterial strain, designated an-8T, was isolated from a freshwater shrimp culture pond in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain an-8T were Gram-reaction-negative, aerobic, rod-shaped and non-motile, formed yellow-pigmented colonies and grew at 15–30 °C (optimum 25 °C), pH 7–8 (optimum pH 8.0) and in 0–1 % (w/v) NaCl (optimum 0 %). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain an-8T belonged to the genus Flavobacterium and its most closely related neighbours were Flavobacterium terrigena DS-20T and Flavobacterium terrae R2A1-13T with sequence similarities of 95.1 and 94.9 %, respectively. Strain an-8T contained iso-C15 : 0, summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c), iso-C16 : 0 3-OH, iso-C15 : 0 3-OH, iso-C17 : 0 3-OH and iso-C15 : 1 as the major fatty acids. The major isoprenoid quinone was MK-6. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidyldimethylethanolamine, phosphatidylserine and several unidentified polar lipids. The G+C content of the genomic DNA was 39.8 mol%. On the basis of the phylogenetic and phenotypic data, strain an-8T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium macrobrachii sp. nov. is proposed. The type strain is an-8T ( = BCRC 17965T  = LMG 25203T).

A Gram-stain-positive bacterial strain, designated as NR2T, isolated from noni (Morinda citrifolia L.) branch was investigated using a polyphasic taxonomic approach. The cells were small coccoid to ovoid, non-spore-forming and motile. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain was a representative of a member of the genus Brachybacterium, to which the most closely related neighbours were Brachybacterium squillarum M-6-3T (97.90 % similarity), Brachybacterium faecium DSM 4810T (97.50 %), Brachybacterium sacelli LMG 20345T (97.41 %), Brachybacterium phenoliresistens phenol-AT (97.36 %), Brachybacterium nesterenkovii DSM 9573T (97.36 %) and Brachybacterium rhamnosum LMG 19848T (97.32 %). The polar lipid profile of strain NR2T consisted of diphosphatidylglycerol, phosphatidylglycerol, unknown phospholipids and unknown glycolipids. The predominant respiratory quinone was MK-8, with MK-9 and MK-7 as minor components. The major fatty acids were anteiso-C15 : 0 and iso-C15 : 0. Strain NR2T was clearly distinguishable from the type strains of related species on the basis of phylogenetic analysis, DNA–DNA hybridization, fatty acid composition data analysis and a range of physiological and comparison of biochemical characteristics. It is evident from the genotypic and phenotypic data that strain NR2T represents a novel species of the genus Brachybacterium, for which the name Brachybacterium hainanense sp. nov. is proposed. The type strain is NR2T ( = DSM 29535T = CICC 10874T).

A yellow-coloured, rod-shaped, Gram-reaction-negative and aerobic bacterial strain, designated JC2675T, was isolated from a seawater sample from Jeju Island, Korea. The isolate required sea salts for growth. Gliding motility was observed. Flexirubin-type pigments were absent. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain JC2675T represented a distinct phyletic line that reflected a novel generic status within the family Flavobacteraceae with relatively low gene sequence similarities (<95.7 %) to other recognized genera. The predominant isoprenoid quinone (MK-6) and DNA G+C content (30 mol%) were consistent with the assignment of the novel strain to the family Flavobacteriaceae, but overall phenotypic traits demonstrated that the novel strain was not closely affiliated with any previously described genus. Based on data from a study using a polyphasic taxonomic approach, it is proposed that strain JC2675T represents a new genus and novel species belonging to the family Flavobacteriaceae, for which the name Pontirhabdus pectinivorans gen. nov., sp. nov. is proposed. The type strain of the type species is JC2675T ( = KACC 14153T = JCM 17107T).
