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