Abstract:
The ice-nucleating bacterium Pantoea ananas KUIN-3 accumulated glucose in cells following a shift in temperature (10 degrees C) from the optimum growth temperature (30 degrees C). This accumulation might be caused by the activation of glucose-6-phosphatase. Although this strain after culturing at 30 degrees C was harmed by freezing, the cryotolerance of this strain was reached about 80% after cold acclimation at 10 degrees C.
