The water activity and pH ranges for growth of Glaciecola punicea (a psychrophile) were extended when this organism was grown at suboptimal rather than optimal temperatures. No such extension was observed for Gelidibacter sp. strain IC158 (a psychrotolerant bacterium) at analogous temperatures. Salinity and pH may be primary physicochemical parameters controlling bacterial community development in sea ice.
当嗜冷菌深红嗜冷杆菌在非最适温度而非最适温度下生长时,其生长的水分活度和pH范围得到了扩展。在类似温度下,对耐冷细菌嗜冷栖热菌IC158菌株未观察到这种扩展。盐度和pH可能是控制海冰中细菌群落发展的主要物理化学参数。
