体外研究 |
It is showed that ME is essential for (S)-2-Hydroxysuccinic acid (L-malic acid) utilization in L.casei.Furthermore,deletion of either the gene encoding the histidine kinase or the response regulator of the TC system resulted in the loss of the ability to grow on (S)-2-Hydroxysuccinic acid,thus indicating that the cognate TC system regulates and is essential for the expression of ME.Transcriptional analyses shows that expression of maeE is induced in the presence of (S)-2-Hydroxysuccinic acid and repressed by glucose,whereas TC system expression is induced by (S)-2-Hydroxysuccinic acid and is not repressed by glucose. |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系，公式为：
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
摩尔浓度计算公式
用本工具协助配置特定浓度的溶液，使用的计算公式为：
开始浓度 x 开始体积 = 最终浓度 x 最终体积
稀释公式
稀释公式一般简略地表示为：C1V1 = C2V2 ( 输入 输出 )
