对从南极洲有机湖中分离到的一组中度嗜盐、异养、有色菌株进行了研究。这些菌株革兰氏阴性，不活动，具有好氧代谢，其DNA的摩尔%G+C含量在35-41之间，表明它们可能是黄杆菌-吞噬黄杆菌群的成员。一项涉及134个特征的数值分类研究将南极菌株与黄杆菌、吞噬细胞菌和弯曲杆菌的参考菌株进行了比较。南极的菌株形成了两个不包含任何参考菌株的簇，这表明它们可能代表了黄杆菌属的两个新物种。
A study was made of a group of moderately halophilic, heterotrophic, pigmented strains isolated from Organic Lake, Antarctica. These strains were Gram-negative, non-motile, had an aerobic metabolism and a mol% G + C content of their DNA in the range 35-41, indicating that they may be members of the Flavobacterium-Cytophaga group. A numerical taxonomic study involving 134 characteristics compared the antarctic strains with reference strains from Flavobacterium, Cytophaga and Flectobacillus. The antarctic strains formed two clusters that did not contain any reference strains suggesting that they may represent two new species of the genus Flavobacterium.
