A cyanide-insensitive and salicyl hydroxamic acid-sensitive respiration (CIR) was found in the yeast Pichia stipitis in contrast to Candida utilis, Pachysolen tannophilus, and Saccharomyces cerevisiae. During xylose utilization in the presence of either salicyl hydroxamic acid or cyanide, P. stipitis formed xylitol, arabitol, and ribitol. The existence of CIR is discussed in terms of a redox sink preventing xylitol formation in P. stipitis.
与 Candida utilis、Pachysolen tannophilus 和 Saccharomyces cerevisiae 不同,酵母 Pichia stipitis 存在对氰化物不敏感且对水杨羟肟酸敏感的呼吸作用(CIR)。当在水杨羟肟酸或氰化物存在的情况下利用木糖时,P. stipitis 会形成木糖醇、赤藓糖醇和核糖醇。本文讨论了 CIR 的存在,认为它是一种氧化还原缓冲液,可以防止 P. stipitis 中木糖醇的形成。
