Abstract:
A Gram-stain-positive, facultatively anaerobic, non-motile, endospore-forming and rod-shaped bacterium, occurring singly or in pairs, designated TB2019 T , was isolated from environmental monitoring samples of corridor air collected at the Tianjin Institute for Drug Control, Tianjin Province (PR China). The isolate was able to grow at 15–40 °C (optimum growth at 37 °C), pH 6.0–8.0 (pH 7.0) and in the presence of 0–2% (w/v) NaCl (0% NaCl). Comparison of 16S rRNA gene sequences indicated that TB2019 T was most closely related to Paenibacillus typhae CGMCC 1.11012 T (98.63%), Paenibacillus albidus Q4-3 T (98.19%), Paenibacillus borealis DSM 13188 T (97.55%), Paenibacillus helianthi P26E T (97.33%) and Paenibacillus odorifer DSM 15391 T (97.19%). The digital DNA–DNA hybridization and the average nucleotide identity values between TB2019 T and the five type strains mentioned above ranged from 20.7 to 25.0% and 75.2 to 81.3%, respectively, and the genomic DNA G+C content was 49.52 mol%. The diagnostic cell-wall sugar was ribose, and the diagnostic amino acid was meso -diaminopimelic acid. The polar lipids of TB2019 T included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, three unidentified aminophospholipids and one unidentified phospholipid. MK-7 was the predominant menaquinone, and anteiso-C 15:0 (30.6%) was the major fatty acid. Based on the polyphasic taxonomic data, strain TB2019 T represents a novel species of the genus Paenibacillus , for which the name Paenibacillus tianjinensis sp. nov. is proposed. The type strain is TB2019 T (=CICC 25065 T =JCM 34610 T ).
