1976年Inoue和Komagata提出的“嗜冷Curtobacterium psychrophilum”是一种从南极土壤中分离出来的嗜冷革兰氏阳性不规则棒。该菌在9 ~ 12℃条件下生长最佳，不高于18℃，其化学分类特征为细胞壁中存在2,4-二氨基丁酸，呼吸醌以甲基萘醌-10为主。细胞脂肪酸谱中含有大量的抗异支化单不饱和酸——12-甲基十四烯酸，这是该生物的一个显著特征，对低温适应是合理的。基于16S核糖体DNA序列的系统发育分析表明，该生物定位于微细菌科的一个独立分支，具有B族肽聚糖的放线菌。我们建议将这种生物命名为嗜冷冷冻细菌gen. nov., sp. nov.。型应变为JCM 1463 （= IAM 12024 = ATCC 43563 = IFO 15735 = NCIMB 2068）。
"Curtobacterium psychrophilum," proposed by Inoue and Komagata in 1976, is a psychrophilic gram-positive irregular rod isolated from Antarctic soil. This organism grew optimally at 9 to 12 degrees C and did not grow at higher than 18 degrees C. Chemotaxonomic characteristics of this organism were the presence of 2,4-diaminobutyric acid in the cell wall and menaquinone-10 as the predominant respiratory quinone. The cellular fatty acid profile, which contained a significant amount of an anteiso-branched monounsaturated acid, 12-methyl tetradecenoic acid, was a distinctive characteristic of this organism and was reasonable for adaptation to low temperature. Phylogenetic analysis based on 16S ribosomal DNA sequences revealed that this organism was positioned at a separate branch in the family Microbacteriaceae, actinomycetes with group B peptidoglycan. We propose the name Cryobacterium psychrophilum gen. nov., sp. nov. for this organism. The type strain is JCM 1463 (= IAM 12024 = ATCC 43563 = IFO 15735 = NCIMB 2068).
