Xylanase refers to a type of enzyme which can hydrolyze xylans into xylooligosaccharides and d - xylose. it broadly exists in microorganism and has wide commerical application in industrial processes, such as feed, paper, foodstuff, medicine and energy industries. the xylanase gene xynb encoding the native protein of xylanase from streptomyces olivaceoviridis a1 was cloned into pichia pastoris expression vector ppic9 a
我們將來源於橄欖綠鏈黴菌a1 （ streptomycesolivaceoviridisa1 ）的木聚糖酶基因xynb的成熟蛋白編碼序列克隆到畢赤酵母表達載體ppic9中，轉化pichiapastorisgs115得到重組子，實現了木聚糖酶基因xynb的高效表達，表達產物能有效分泌且具有正常的生物學活性。 -
First of all, both r & d labor and r & d capital input variables are introduced into the input vector, and a two - level ces production function model is constructed to describe the technology of production. then the firm - level cross - section data of shanghai ’ s main manufacturing industries in 2003 is employed to study the input - output effect of r & d as well as the substitution relationship among input factors. moreover, the thesis also makes a methodological discussion of multicollinearity, and proposes a feasible approach to deal with the problem
首先，在生產函數的投入要素向量中引入r & d投入變量，包括r & d人力投入和r & d資本投入;然後，結合相關的研究經驗和本文的研究目的，構建了相應的二級ces生產函數模型;在此基礎之上，採用2003年上海主要製造業企業的橫截面數據，分行業研究了r & d投入對產出的作用以及r & d投入與非r & d投入之間的替代關系。
