Abstract
Strain Ran72T, a novel Gram-stain-negative, obligately aerobic, non-motile, and rod-shaped bacterium, was isolated from the faeces of the rhinoceros species Ceratotherium simum. The novel bacterial strain grew optimally in Reasoner's 2A medium under the following conditions: 0 % (w/v) NaCl, pH 7.5, and 30 °C. Based on phylogenetic analysis using 16S rRNA gene sequencing, strain Ran72T was found to be most closely related to Chryseobacterium faecale F4T (98.4 %), Kaistella soli DKR-2T (98.0 %), and Kaistella haifensis H38T (97.4 %). A comprehensive genome-level comparison between strain Ran72T with C. faecale F4T, K. soli DKR-2T, and K. haifensis H38T revealed average nucleotide identity, digital DNA-DNA hybridization, and average amino acid identity values of ≤74.9, ≤19.3, and ≤78.7 %, respectively. The major fatty acids were anteiso-C15 : 0 (22.3 %), with MK-6 being the predominant respiratory quinone. The major polar lipids of strain Ran72T were phosphatidylethanolamine, four unidentified aminolipids, and two unidentified lipids. Based on our chemotaxonomic, genotypic, and phenotype characterizations, strain Ran72T was identified as representing a novel species in the genus Kaistella, for which the name Kaistella rhinocerotis sp. nov. is proposed, with the type strain Ran72T (=KACC 23136T=JCM 36038T). Based on the outcomes of our phylogenomic study, Chryseobacterium faecale should be reclassified under the genus Kaistella as Kaistella faecalis comb. nov.

Abstract
A Gram-stain-negative, aerobic, non-motile, rod-shaped bacterium, designated LAMRS1T, was isolated from a soil sample collected in Hebei Province, PR China. Strain LAMRS1T was able to grow optimally in the presence of 0.5 % (w/v) NaCl, at pH 7.5 and at 30 °C. On the basis of 16S rRNA gene sequence analysis, strain LAMRS1T was closely related to members of the genus
Chryseobacterium
, with highest levels of sequence similarity to
Chryseobacterium soli
DSM 19298T (97.9 %),
Chryseobacterium soldanellicola
DSM 17072T (97.6%) and
Chryseobacterium piperi
CTMT (97.5 %). The average nucleotide identity and digital DNA–DNA hybridization values between LAMRS1T and the closely related species of
C. soli
DSM 19298T,
C. soldanellicola
DSM 17072T and
C. piperi
CTMT were 78.1, 78.2 and 80.7 %, and 21.7, 22.0 and 23.7 %, respectively. The draft genome sequence of LAMRS1T was 4.61 Mb, with DNA G+C content of 36.2 mol%. The major isoprenoid quinone was menaquinone-6 and iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1
ω6c and/or C16 : 1
ω7c) constituted the major cellular fatty acids. The main polar lipids were phosphatidylethanolamine, four aminolipids, three glycolipids and seven unidentified lipids. On the basis of evidence presented in this study, strain LAMRS1T represents a novel species of the genus
Chryseobacterium
, for which the name Chryseobacterium subflavum sp. nov. is proposed. The type strain is LAMRS1T (=JCM 33868T=KCTC 72823T).

Abstract
A Gram-negative, aerobic, motile, rod-shaped, pale-yellow bacterial strain, designated as ZYLT, isolated from a cultured in situ sediment sample collected from the East China Sea coast, was studied using a polyphasic taxonomic approach. Strain ZYLT grew at 4-30 °C (optimum, 25 °C), at pH 6.0-8.5 (pH 7.0) and with 0-7.0 % (w/v) NaCl (2.0 %). Results of phylogenetic analysis based on 16S rRNA gene sequences clearly showed that strain ZYLT and Emcibacter nanhaiensis HTCJW17T, which was most closely related to strain ZYLT with 93.6 % sequence similarity, clustered together. The genomic DNA G+C content was 51.5 % (genome sequence). The quinone system was composed only of ubiquinone-10. Strain ZYLT possessed C18 : 1ω7c and/or C18 : 1ω6c (summed feature 8), iso-C15 : 0 2-OH and/or C16 : 1ω7c (summed feature 3), C14 : 0 2-OH and C14 : 0 as the major fatty acids. The content of summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c) in strain ZYLT was far greater than that in E. nanhaiensis. The polar lipid profile consisted of phosphatidylethanolamine, phosphatidylglycerol, three unidentified aminophospholipids, three unidentified phospholipids, one unidentified aminolipid and four unidentified lipids. One unidentified aminophospholipid and two unidentified lipids present in strain ZYLT were not found in E. nanhaiensis in this research. On the basis of phenotypic, phylogenetic and chemotaxonomic data, strain ZYLT (=KCTC 62328T=JCM 32378T=MCCC 1K03526T) represents a novel species of the genus Emcibacter for which the name Emcibacter congregatus sp. nov. is proposed.
