Pseudomonas deceptionensis sp. nov., a psychrotolerant bacterium from the Antarctic

During the taxonomic investigation of cold-adapted bacteria from samples collected in theAntarctic area of the South Shetland Islands, one Gram-reaction-negative, psychrotolerant,aerobic bacterium, designated strain M1T, was isolated from marine sediment collected onDeception Island. The organism wa...
