摘要
A Gram-reaction-negative, aerobic, non-motile, non-spore-forming, rod-shaped bacterium, designated YX-36(T), was isolated from a vegetable plot in Yixing, Jiangsu province, China. The strain grew at 15-37 degrees C (optimally at 37 degrees C), at pH 6.0-9.5 (optimally at pH 6.5) and in the presence of 0-1 % (w/v) NaCl (optimally without NaCl). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YX-36(T) was related most closely to Mucilaginibacter herbaticus DR-9(T) (96.88 % similarity), followed by Mucilaginibacter sabulilitoris SMS-12(T) (95.78 %), Mucilaginibacter polysacchareus DR-f3(T) (95.77 %) and Mucilaginibacter polysacchareus DRP28(T) (95.77 %). The DNA G+ C content of strain YX-36(T) was 47.2 mol%. The only isoprenoid quinone was menaquinone 7 (MK-7). The major polar lipids were phosphatidylethanolamine and aminophospholipid. The major fatty acids were iso-C-15 (: 0), summed feature 3 (iso-C-15 : 0 2-OH/C-16 : 1 omega 7c) and iso-C-17 : 0 3-OH. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain YX-36(T) represents a novel species of the genus Mucilaginibacter, for which the name Mucilaginibacter yixingensis sp. nov. is proposed. The type strain is YX-36(T) (=DSM 26809(T) =CCTCC AB 2012880(T)).
