suicide substrates meaning in Chinese
自杀底物
Examples
- Two pta - mutants have been selected by using suicide substrate after the mini - tn5 transposon insertion mutagenesis of klebsiella pneumoniae m5al . when used in microaerobic fermentation , the amount of acetate produced by the mutants reduced to less than 50 % of the parent strain , and the yields improved whereas the 1 , 3 - propanediol titers and productivities decreased
以klebsiellapneumoniaem5al为出发菌株，用mini - tn5随机转座诱变结合自杀性底物筛选的方法得到了两株产乙酸途径pta基因缺失突变株xl - 6和xl - 11 ，应用到微氧法发酵中，突变株的乙酸产量为亲株的50以下，甘油转化率有所提高，但1 ， 3 -丙二醇浓度和生产强度有所下降。
