Abundance of general aerobic heterotrophic bacteria in the Bering Sea and Chukchi Sea and their adaption to temperature
The abundance of general aerobic heterotrophic bacteria (GAB) from the water and sediment in the Bering Sea and the Chukchi Sea was determined by using petri dish cultivation and counting method. The abundance of GAB among the different sea area, sampling sites, layers of sediments surveyed and adap...
