| 摘 要： | 该研究以酵母破壁酶、蜗牛酶破碎酿酒酵母（Saccharomyces cerevisiae）细胞壁，再使用总核糖核酸（RNA）提取试剂（TRIzol）法提取酵母总RNA，通过对总RNA进行浓度与纯度的分析，比较酶处理对RNA提取的影响。结果表明，酵母破壁酶的最佳提取条件为加酶量37.5 μL，提取温度27 ℃，提取时间15 min。在此最佳提取条件下，提取RNA质量浓度为1 079.05 ng/μL，A260 nm/A280 nm为2.10，A260 nm/ A230 nm为2.15；蜗牛酶的最佳提取条件为加酶量30 mg/mL，提取温度37 ℃，提取时间30 min。在此最佳提取条件下，提取RNA质量浓度为1 673.39 ng/μL，A260 nm/A280 nm为1.99，A260 nm/A230 nm为1.81。结果显示，酵母破壁酶的提取效果优于蜗牛酶。

| Abstract: | The cell wall of Saccharomyces cerevisiae was broken using yeast lyticase and snailase, and then the total ribonucleic acid (RNA) of yeast was extracted by total RNA extraction reagent (TRIzol) method. Through the analysis of the concentration and purity of the total RNA, the effect of enzyme treatment on RNA extraction was compared. The results showed that the optimal extraction conditions of yeast lyticase were enzyme addition 37.5 μl, extraction temperature 27 ℃, and extraction time 15 min. Under the optimal extraction conditions, the mass concentration of RNA was 1 079.05 ng/μl, A260 nm/A280 nm was 2.10, and A260 nm/A230 nm was 2.15. The optimal extraction conditions of snailase were enzyme addition 30 mg/ml, extraction temperature 37 ℃, and extraction time 30 min. Under the optimal extraction conditions, the mass concentration of RNA was 1 673.39 ng/μl, A260 nm/A280 nm was 1.99, and A260 nm/A230 nm was 1.81. At the same time, it was found that the extraction effect of yeast lyticase was better than that of snailase. |
