摘要

从乌克兰克里米亚Nikitsky植物园毛竹根际样品中分离到一株放线菌，命名为Pv 4-285T。菌株pv4 -285 T与湘鹿Mumia NEAU-KD1T的16S rRNA基因序列相似性最高。基因组大小为4.6 Mbp， DNA G+C含量为70.43%。该分离物革兰氏染色阳性，无孢子形成，无运动，需氧。细胞呈不规则杆状。Pv - 4-285T能够在20-37℃、pH 6.0-9.0和高达6% (w/v) NaCl的存在下生长。甲基萘醌主要为MK-9（H4）。菌株pv4 - 285t的极性脂质谱由二磷脂酰甘油、磷脂酰甘油、磷脂酰肌醇甘露糖和磷脂酰肌醇组成。pv4 -285含有C16:0， С18:1 ω9c， 10-甲基C18:0， C17:0。而菌株Pv 4-285T的全细胞糖含量为半乳糖、甘露糖和木糖。基于这些差异，菌株Pv 4-285T （=DSM 118545T =LMG 33743T）应该被归类为Mumia qirimensis sp. nov的新种类型菌株。

Mumia qirimensis sp. nov. isolated from the rhizosphere of Phyllostachys viridiglaucescens (Carrière) Rivière & C. Rivière.

A novel actinomycete strain, designated Pv 4-285^T, was isolated from rhizosphere sample collected from Phyllostachys viridiglaucescens growing in the Nikitsky Botanical Garden, Crimea, Ukraine. The strain Pv 4-285 ^T shared the highest 16S rRNA gene sequence similarity with Mumia xiangluensis NEAU-KD1^T. The genome size was 4.6 Mbp with a DNA G+C content of 70.43%. The isolate was Gram-stain-positive, non-spore-forming, non-motile and aerobic. Cells were observed to be irregularly rod-shaped. Pv 4-285^T was able to grow at 20-37 °C and at pH 6.0-9.0 and in the presence of up to 6% (w/v) NaCl. The predominant menaquinone was detected as MK-9(H₄). The polar lipid profile of strain Pv 4-285^T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol mannoside and phosphatidylinositol. Pv 4-285 contained C_16:0, С_18:1 ω9c, 10-methyl C_18:0, C_17:0. While galactose, mannose and xylose were detected in strain Pv 4-285^T as the whole-cell sugars. Based on these differences, strain Pv 4-285^T (=DSM 118545^T =LMG 33743^T) should be classified as the type strain of a novel species of Mumia, for which the name Mumia qirimensis sp. nov. is proposed.

期刊介绍： Published by the Microbiology Society and owned by the International Committee on Systematics of Prokaryotes (ICSP), a committee of the Bacteriology and Applied Microbiology Division of the International Union of Microbiological Societies, International Journal of Systematic and Evolutionary Microbiology is the leading forum for the publication of novel microbial taxa and the ICSP’s official journal of record for prokaryotic names. The journal welcomes high-quality research on all aspects of microbial evolution, phylogenetics and systematics, encouraging submissions on all prokaryotes, yeasts, microfungi, protozoa and microalgae across the full breadth of systematics including: Identification, characterisation and culture preservation Microbial evolution and biodiversity Molecular environmental work with strong taxonomic or evolutionary content Nomenclature Taxonomy and phylogenetics.
