The aerobic chemoorganotrophic bacteria, dominating in soils and phytocenosis of the Antarctic Region, on combination of morphological and biochemical properties belong to several taxons of Bacteria domain. Gram-negative strains 3189, 3415 (fam. Halomonadaceae, Halomonas sp.) and 3088, 3468, 3469 (fam. Moraxellaceae, Psychrobacter sp.) belong to phylum Proteobacteria, to class Gammaproteobacteria. Gram-negative strains 3294 3392 (Rhizobiales, fam. Methylobacteriaceae, Methylobacterium sp.) relate to class Alphaproteobacteria of this phylum. Gram-positive strains 3179, 3275, 3470, 3471 (fam. Microbacteriaceae, Cryobacterium sp.), 3054, 3058, 3411 (fam. Corynebacteriaceae, Corynebacterium sp.) and 3194, 3398 (fam. Micrococcaceae, Micrococcus sp.) relate to phylum Actinobacteria, class Actinobacteria. Thus, the psychrophilic and psychrotolerant Antarctic bacteria (aerobic chemoorganotrophic) isolated from phytocenosis and soils of polar region are characterized by wide taxonomic variety.
在南极地区的土壤和植物群落中占主导地位的需氧化学有机营养细菌，根据形态和生化特性的组合，属于细菌域的几个分类单元。革兰氏阴性菌株3189、3415（盐单胞菌科，盐单胞菌属）和3088、3468、3469（莫拉克斯氏菌科，嗜冷杆菌属）属于变形菌门，γ-变形菌纲。革兰氏阴性菌株3294、3392（根瘤菌目，甲基杆菌科，甲基杆菌属）属于该门的α-变形菌纲。革兰氏阳性菌株3179、3275、3470、3471（微杆菌科，嗜冷杆菌属）、3054、3058、3411（棒杆菌科，棒杆菌属）和3194、3398（微球菌科，微球菌属）属于放线菌门，放线菌纲。因此，从极地地区的植物群落和土壤中分离出的嗜冷和耐冷南极细菌（需氧化学有机营养细菌）具有广泛的分类多样性。
