Substances cryoprotective for Vibrio cholerae were detected from prawn shells immersed in phosphate-buffered saline. This cryoprotective activity was heat resistant and sensitive to treatment with trypsin. For the exhibition of its full activity, the presence of Mg ion was indispensable. The cryoprotective activity of this substance was more active than that of other known cryoprotectants, like glycerol or serum.
在浸泡于磷酸盐缓冲盐溶液中的虾壳中检测到了对霍乱弧菌具有冷冻保护作用的物质。这种冷冻保护活性具有耐热性,并且对胰蛋白酶处理敏感。为了展现其全部活性,镁离子的存在是必不可少的。该物质的冷冻保护活性比其他已知的冷冻保护剂(如甘油或血清)更具活性。
