parent strain meaning in English
亲株
Examples
- To improve the strain " s lipase yield , it was treated by means of uv mutagenesis . the mutant lzl - 10 was selected and produced lipase activity 10 % higher than that of parent strain
经五次紫外线诱变后，筛选到突变株lzl一10 ，其产酶量较出发菌株提高了10 % 。 - The acetaldehyde dehydrogenase ( acdh ) and alcohol dehydrogenase ( adh ) of the adhe mutants and parent strain were assayed with a result that the acdh activities of mutants were less than 10 % of the parent strain and the adh activities of mutants are about 10 % of the parent strain
6个adhe ~ -突变株的乙醛脱氢酶活性均降低为亲株的10以下，乙醇脱氢酶活性降低为亲株的10左右； 4个ldha ~ -突变株的乳酸脱氢酶活性均降低为亲株的7以下。 - 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。
