在厌氧条件下，盐水虾（a.s alina）的胚胎进入深度休眠状态。利用体内31P核磁共振，在厌氧休眠和好氧发育之间的可逆转变伴随着细胞内pH值的大变化（>.1单位），更酸性的pH值与休眠状态有关。休眠囊肿的细胞内pH值与缓冲液的pH值无关，这表明在休眠期间pH可能介导酶活性的调节。讨论了一个关于囊肿核苷酸代谢的例子。
Encysted embryos of the brine shrimp, A. salina, enter profound dormancy under anaerobic conditions. Utilizing in vivo 31P nuclear magnetic resonance, the reversible transitions between anaerobic dormancy and aerobic development were accompanied by large (> 1 unit) intracellular pH changes, the more acid pH being associated with the dormant state. Dormant cyst intracellular pH is independent of that of the buffer, suggesting the potential for pH-mediated regulation of enzyme activities during dormancy. An example concerning cyst nucleotide metabolism is discussed.
