摘要：

We examined the Arctic bacterium Colwellia psychrerythraea strain 34H for motility at temperatures from -1 to -15degreesC by using transmitted-light microscopy in a temperature-controlled laboratory. The results, showing motility to -10degreesC, indicate much lower temperatures to be permissive of motility than previously reported (5degreesC), with implications for microbial activity in frozen environments.
