Mesophilic Bacterium

A mesophilic bacterium, designated strain YIM 31327T, was isolated from a forest soil sample collected from Yunnan Province, China, and was then investigated using a polyphasic approach. The strain grew optimally at 28–30 °C and pH 7·2. The cells were Gram-negative, short, rod-shaped, motile and non-spore-forming with flagella. The major ubiquinone was Q-8 and the cellular fatty acids were C16 : 0 and C12 : 0. The DNA G+C content of strain YIM 31327T was 62·8 mol%. Phylogenetic analysis revealed that strain YIM 31327T was a member of the β-Proteobacteria, being most closely related to Duganella zoogloeoides, with which it exhibited less than 96 % 16S rRNA gene sequence similarity. On the basis of the phenotypic and genotypic differences between strain YIM 31327T and D. zoogloeoides, a novel species, Duganella violaceinigra sp. nov., is proposed, with YIM 31327T (=CIP 108077T=KCTC 12193T) as the type strain.

Two Gram-stain-positive bacterial isolates, strain 2385/12T and strain 2673/12T were isolated from a tapir and a dog's nose, respectively. The two strains were rod to coccoid-shaped, catalase-positive and oxidase-negative. The highest 16S rRNA gene sequence similarity identified Corynebacterium singulare CCUG 37330T (96.3 % similarity) as the nearest relative of strain 2385/12T and suggested the isolate represented a novel species. Corynebacterium humireducens DSM 45392T (98.7 % 16S rRNA gene sequence similarity) was identified as the nearest relative of strain 2673/12T. Results from DNA–DNA hybridization with the type strain of C. humireducens demonstrated that strain 2673/12T also represented a novel species. Strain 2385/12T showed a quinone system consisting predominantly of menaquinones MK-8(H2) and MK-9(H2) whereas strain 2673/12T contained only MK-8(H2) as predominant quinone. The polar lipid profiles of the two strains showed the major compounds phosphatidylglycerol, diphosphatidylglycerol and an unidentified glycolipid. Phosphatidylinositol was identified as another major lipid in 2673/12T whereas it was only found in moderate amounts in strain 2385/12T. Furthermore, moderate to minor amounts of phosphatidylinositol-mannoside, β-gentiobiosyl diacylglycerol and variable counts of several unidentified lipids were detected in the two strains. Both strains contained corynemycolic acids. The polyamine patterns were characterized by the major compound putrescine in strain 2385/12T and spermidine in strain 2673/12T. In the fatty acid profiles, predominantly C18 : 1ω9c and C16 : 0 were detected. The two strains are distinguishable from each other and the nearest related established species of the genus Corynebacterium phylogenetically and phenotypically. In conclusion, two novel species of the genus Corynebacterium are proposed, namely Corynebacterium tapiri sp. nov. (type strain, 2385/12T = CCUG 65456T = LMG 28165T) and Corynebacterium nasicanis sp. nov. (type strain, 2673/12T = CCUG 65455T = LMG 28166T).
