This investigation aims to screen out the high - yield acidic phytase - producing microbial strains and men further to select for high yield strains by mutagenesis and still then to clone and analyze the phytase gene in the high - yield phytase - producing mutant strains . on these bases , to construct high yield phytase gene engineered microbial strains for the industrialized production of phytase . main results are as follows
本研究的目的旨在通过从土壤中筛选酸性植酸酶高产菌株，并进一步通过诱变选育提高其产量，对高产突变菌株植酸酶基因进行克隆和分析，在此基础上，构建植酸酶高产基因工程菌，从而为植酸酶产品的工业化生产奠定基础。
In this paper , the ductility of steel bar is expressed by ductility ratio b , the figure of dividing ultimate strain by yield strain . the ductility of section is expressed by ductility of section ratio , the figure of dividing ultimate curvature by yield curvature . the displacement ductility is expressed by displacement ductility ratio , the figure of dividing ultimate displacement by yield displacement
论文中钢筋延性采用钢筋延性比b来表示，即极限应变与屈服应变的比值；构件截面延性采用截面延性比来表示，即极限曲率与屈服曲率的比值；构件位移延性采用位移延性比_来表示，即极限位移与屈服位移的比值。
