A yellow-pigmented, Gram-stain-negative, gliding and rod-shaped bacterial strain, designated zong2l5T , was isolated from a forest soil sample at Dinghu Mountain, Guangdong Province, PR China. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain zong2l5T belongs to the genus Lysobacter, and was most closely related to Lysobacter enzymogenes KCTC 12131T (97.7 %) and Lysobacter soli KCTC 22011T (97.6 %). The novel strain showed an average nucleotide identity (ANI) value of 81.5 % and a digital DNA-DNA hybridization (dDDH) value of 25...

Two isolates of heterotrophic, facultatively anaerobic, marine bacteria, designated DM1 and DM2T , were recovered from a lagoon sediment sample of Dongsha Island, Taiwan. Cells were Gram-reaction-negative rods. Nearly all of the cells were non-motile and non-flagellated during the late exponential to early stationary phase of growth, while a few of the cells exhibited motility with monotrichous flagellation. The two isolates required NaCl for growth and grew optimally at about 30 °C, 2-3 % NaCl and pH 7-8...

Seven endophytic strains were isolated from the halophyte Halimione portulacoides, collected from Ria de Aveiro, Portugal. To determine their exact taxonomic position, comparative analyses were performed with these strains and closely related type strains of Salinicola species. Genome sequencing and comparison indicated that five of the seven isolated strains comprised distinct and novel species (average nucleotide identity <0.95; in silico DNA-DNA hybridization <70 %; G+C difference >1 %). Multilocus sequence analysis was performed using gyrB, rpoD and 16S rRNA gene sequences from the novel and type strains to determine their phylogenetic positions...

A strain of a member of the genus Klebsiella, WCHKl090001, was recovered from a human urine sample in PR China in 2017. Phylogenetic analysis based on gyrA and rpoB housekeeping genes revealed that the strain was distinct from any previously described species of the genus Klebsiella though it was clustered with the Klebsiella oxytoca phylogroup, including Klebsiella grimontii, Klebsiella michiganensis and Klebsiella oxytoca. The whole-genome sequence of strain WCHKl090001 has an up to 87.18 % average nucleotide identity with those of type strains of all known species of the genus Klebsiella...

A Gram-stain-negative, aerobic, non-spore-forming and rod-shaped bacterium, designated YIM 730274T , was isolated from a sediment sample collected from a hot spring located in Tibet, PR China, and was characterized by using a polyphasic taxonomy approach. Cells were motile by means of a polar flagellum. The strain was oxidase- and catalase-positive, and contained polyalkanoates and polyphosphate as storage polymers. Growth occurred at 25-50 °C, at pH 6.0-8.5 and with 0.5-1.0 % NaCl.

Two strains (RW43-9T and RW17-10T ) recovered from secondary treated wastewater from the Wastewater Treatment Plant (WWTP) in Reus (Spain) were characterized by a polyphasic taxonomic study, showing evidence that they represented two novel Arcobacter species. Based on the 16S rRNA gene for strain RW43-9T , the closest relative was Arcobacter butzleri LMG 10828T (99.9 % similarity), while for strain RW17-10T it was Arcobacter venerupis CECT 7836T (99.4 %). Additionally, multilocus phylogenetic analysis of five concatenated housekeeping genes (atpA, gyrA, gyrB, hsp60 and rpoB) showed that the two strains formed separate branches that are different from known Arcobacter species...

In the present study, we describe two novel Gram-stain-positive, irregular rod-shaped bacterial strains, 78T and 601, that had been isolated from the faeces of Tibetan antelopes at the Hoh Xil Nature Reserve, Qinghai-Tibet Plateau, China. The cells were aerobic, oxidase-negative and catalase-positive. When cultured on brain-heart infusion agar supplemented with 5 % sheep blood, colonies were cream in colour, circular, smooth and convex. Phylogenetic analysis based on the full-length 16S rRNA sequences revealed that type strain 78T and strain 601 belong to the genus Nocardioides, sharing the highest similarity to Nocardioides solisilvae JCM 31492T (98...
