Eight strains of chemoorganotrophic bacteria were isolated from the water column of Lake Hoare, McMurdo Dry Valleys, Antarctica, using cold enrichment temperatures. The isolates were Alpha-, Beta-, and Gammaproteobacteria and Actinobacteria spp. All isolates grew at 0 degrees C, and all but one grew at subzero temperatures characteristic of the water column of Lake Hoare. Growth temperature optima varied among isolates, but the majority showed optima near 15 degrees C, indicative of cold-active ...[more]
