Abstract

A gram-positive, aerobic, slowly growing actinomycete was isolated from antarctic sandstone. Packets of spherical cells of this organism form clusters. The diagnostic diamino acid of the peptidoglycan is LL-diaminopimelic acid with glycine in position 1 of the peptide subunit. The major menaquinone is MK-9(H4), and the main cellular fatty acids are 12- and 13-methyltetradecanoic acids. Only a few organic compounds are metabolized. The DNA base composition is 73 mol% G + C. A 16S ribosomal DNA sequence comparison showed that this isolate is a phylogenetic neighbor of the propionibacteria and related taxa. Its closest relative is Microlunatus phosphovorus. Morphological, physiological, and genotypic characteristics support the description of a new genus and new species, Friedmanniella antarctica gen. nov., sp. nov. The type strain is strain AA-1042 (= DSM 11053).

摘要

从南极砂岩中分离出一株革兰氏阳性、需氧、生长缓慢的放线菌。该微生物的球形细胞包形成簇。肽聚糖的诊断性二氨基酸是LL-二氨基庚二酸，肽亚基的第1位为甘氨酸。主要的甲基萘醌是MK-9(H4)，主要的细胞脂肪酸是12-和13-甲基十四烷酸。仅能代谢少数有机化合物。DNA碱基组成为73 mol% G + C。16S核糖体DNA序列比较表明，该分离株是丙酸杆菌属及相关分类单元的系统发育近缘种。其最亲近的亲缘种是磷微月菌。形态、生理和基因型特征支持描述一个新属和新种，即南极弗里德曼氏菌属，新属，新种。模式菌株是AA-1042菌株(= DSM 11053)。
