英文摘要	Two psychrotolerant facultative anaerobes, strains B7-2(T) and B5(T), were isolated from the Zoige Wetland on the Qinghai-Tibetan Plateau. The 16S rRNA gene sequences of strains B7-2(T) and B5(T) shared high similarity (>99?%) with those of the type strains of the genus Trichococcus, while their digital DNADNA hybridization values with each other (49?%) and with the reference type strains (4823?%) were lower than 70?%, which suggest that they represent two novel species of the genus Trichococcus. Cells of strains B7-2(T) and B5(T) were immotile cocci, grew in the temperature range of 437 degrees C (optimum 25 degrees C) and were alkaliphilic with optimum growth at pH 9.0. The major components of the cellular fatty acids were C-16:0, anteiso-C-17:0 and C-18:0 for strain B7-2(T), and C-16:0, anteiso-C-17:0, C-18:1 omega 9c and C-18:0 for strain B5(T). The genomic DNA G+C contents were 46.0 and 46.7 mol% for strains B7-2(T) and B5(T), respectively. Based on physiological and genomic characteristics, it is suggested that strains B7-2(T) and B5(T) represent two novel species within the genus Trichococcus, for which the names Trichococcus paludicola sp. nov. and Trichococcus alkaliphilus sp. nov. are proposed. The type strains are B7-2(T) (=DSM 104691T=KCTC 33886(T)) and B5(T) (=DSM 104692(T)=KCTC 33885(T)), respectively.
