Abstract

Several cold-adapted strains isolated from a variety of algal-rich Antarctic and Southern Ocean samples formed three distinct groups within the class Flavobacteria, phylogenetically distant from other cultivated species. The first taxon, designated Algoriphagus ratkowskyi gen. nov., sp. nov., was isolated from sea ice and from saline lake cyanobacterial mats and includes non-motile, strictly aerobic, saccharolytic rod-like or serpentine strains that were most closely related to the genus Cyclobacterium according to 16S rDNA sequence analysis (sequence similarity 0.85). The second taxon, designated Brumimicrobium glaciale gen. nov., sp. nov., isolated from sea ice and from continental shelf sediment, formed gliding, rod-like cells that were facultatively anaerobic with a fermentative metabolism. The third taxon, designated Cryomorpha ignava gen. nov., sp. nov., isolated from Southern Ocean particulates and from quartz stone subliths, included strictly aerobic, pleomorphic rod-like cells. Brumimicrobium glaciale and Cryomorpha ignava were most closely allied with 'Microscilla aggregans var. catalatica', which, on the basis of its distinctive taxonomic traits, is also proposed as a new genus and species, Crocinitomix catalasitica gen. nov., sp. nov. It is proposed that the three genera Brumimicrobium, Cryomorpha and Crocinitomix belong to a new family, Cryomorphaceae fam. nov. (type genus Cryomorpha), as they possess generally similar morphological and ecophysiological characteristics and form a common and distinct clade within class Flavobacteria.
