The temperature dependence of the oxygen isotope fractionation factor during respiration has been examined for two different microorganisms, namely Torulopsis utilis and Escherichia coli K12 representing a yeast and a bacterium, respectively. The investigation covered a temperature range of 18 degrees C, that is from 16 degrees C to 34 degrees C for T. utilis and from 19 degrees C to 37 degrees C for E. coli K12. Within this temperature range the fractionation factor of T. utilis increases by 0.18% an insignificant change (delta delta 10 degrees C = 0.063%; r = 0.067), whereas with E. coli K12 an increase of 1.12% has been observed (delta delta 10 degrees C = 0.6%; r = 0.55).
已针对两种不同的微生物研究了呼吸过程中氧同位素分馏因子的温度依赖性，这两种微生物分别是代表酵母的产朊假丝酵母和代表细菌的大肠杆菌K12。研究涵盖的温度范围为18摄氏度，即产朊假丝酵母的温度范围是16摄氏度至34摄氏度，大肠杆菌K12的温度范围是19摄氏度至37摄氏度。在此温度范围内，产朊假丝酵母的分馏因子增加了0.18%，变化不显著（10摄氏度时的变化量δδ = 0.063%；相关系数r = 0.067），而大肠杆菌K12的分馏因子增加了1.12%（10摄氏度时的变化量δδ = 0.6%；相关系数r = 0.55）。
