The pH within the core or central region of dormant spores of Bacillus cereus and B. megaterium is 6.3-6.4 irrespective of the external pH. However, the spore's internal pH rises to 7.3-7.5 upon germination. The low internal pH of the dormant spore may be a contributing factor to its metabolic dormancy.
蜡样芽孢杆菌和巨大芽孢杆菌休眠孢子核心或中心区域内的pH值为6.3 - 6.4,与外部pH值无关。然而,孢子在萌发时内部pH值会升至7.3 - 7.5。休眠孢子内部的低pH值可能是其代谢休眠的一个促成因素。
