  1. In this experiment, seedlings of arabidopsis thaliana ( col ) were observed after being treated by verlicillium dahliae ( vd - toxin ), exogenous salicylic acid ( sa ), nitric oxide donor ( snp ) and nitric oxide synthase inhibitor ( nna ), then we investigated the changes of endogenous h2o2 content, the activity of the antioxidant enzymes catalase ( cat, ec : 1. 11. 1. 6 ) and ascorbate peroxidase ( apx, ec : 1. 11. 1. 11 ) and mrna levels of cat3 in different stress conditions, we also identified the localizations of h2o2 and no accumulated in the leaves of arabidopsis

    本實驗研究了棉花黃萎病菌?大麗輪枝菌毒素（ vd - toxin ）與擬南芥幼苗互作反應中外源sa 、 no供體snp 、 no合酶抑制劑nna等不同處理對擬南芥幼苗h _ 2o _ 2含量、 cat和apx活性及cat基因mrna表達量的影響，並對no 、 h _ 2o _ 2的積累部位進行染色檢測。
  2. The study results of this paper can serve the two scientific subjects of our teaching and research group as basic data calculation and elementary exploration. the two subjects are : constructing high activity - amylase genes by dna shuffling technology and studying on the evolution in vitro by mutational pcr ( with 5 - br - dutp as substitute partly ) and dna shuffling technology. - amylase ( ec 3. 2. 1. 1 ; 1, 4 - a - d - glucanohydrolase ) can catalyzes the hydrolysis of - 1, 4 - glycosidic bonds of starch from middle and liberates - maltose, - glucose and - limit dextrin stepwise

    本試驗根據genbank已公布的黃單胞菌-澱粉酶基因的核苷酸序列由引物設計軟體premierprimer5 . 0輔助設計了一對引物（ primer & primer ） ，以pbluescript ks +和puc18 / puc19質粒為載體，用常規的pcr方法從xanthomonascampestrispv . malvacearum （ smith ） dye等七株黃單胞菌（ xanthomomasspp . ）的基因組dna中克隆得到8個基因片段，分別命名為zhyf001 zhyf008 。
  3. This experiment passing to grope for the carbon source constitutes of the culture medium and using t. reesei rut c - 30 induced the expression of # - mannanase ( # - 1, 4 - mannan mannohydrolase ec 3. 2. 1. 78 ). in this experiment i put the constant carbon source ( lactose and locust bean gum ) in the foundation culture medium ( mandels nourishment liquid ) of t. reesei rut c - 30, then proceeded the variable carbon source ( dragon spruce fiber, com rush pith fiber, wheat straw fiber, wheat straw xylan, corn rush pith xylan, dragon spruce mannan ) to single factor, double factor, three factor, four factor and five factor orthogonal experiment. 1 determined the activity of p - mannanase using locost bean gum as substract by the 3, 5 - dinitosalicylic acid method, and observed the growing situation of the gernic at the end i selected the directions for the inducement expression of the # ? mannanase from trichoderma reesei rut - c30 that contained the dragon spruce fiber, wheat straw xylan, dragon spruce mannan

    在里氏木霉rutc - 30的基礎培養基（ mandels營養液）中加入固定碳源乳糖和槐豆膠，然後將可變碳源（雲杉纖維、玉米芯纖維、麥桿纖維、麥桿木聚糖、玉米芯木聚糖、雲杉甘露聚糖）進行單因子、雙因子、三因子、四因子、五因子的里氏木霉rutc - 30正交培養實驗，並以槐豆膠為底物用3 ， 5二硝基水楊酸法測定培養液中?甘露聚糖酶的活力。從而確定了酶活最高且菌體生長良好的含雲杉纖維、麥桿木聚糖和雲杉甘露聚糖的誘導培養基為最佳培養基，用該培養基培養的里氏木霉（ t . reesei ） rutc - 30使其轉錄的-甘露聚糖酶（ - 1 ， 4 - mannanmannohydrolaseec3 . 2 . 1 . 78 ） mrna量能夠滿足rt - pcr的要求。
  4. 3. 2. 1. 4 ) which was prepared by precipitation of the water extract of the culture of aspergillus niger with ammonium sulfate and desalted by sephadex g - 25, and was further fractionated by two steps of deae - toyopearl 650m and one step of poros 20pi chromatography. the other was a p - glucosidase ( ec. 3. 2. 1. 21 ) which was prepared by the above g - 25 fractions and was further fractionated by two steps of deae - toyopearl 650m chromatography. the specific activity of the endoglucanase with sodium carboxymethyl cellulose was estimated to be 433. 38 hj / mg

    -葡萄糖苷酶對水楊素的比活力為597 . 12iu mg ，並對其專一，不能水解棉花和羧甲基纖維素鈉；分子量為117 . 5kda ，加dtt後分子量不變；該組分最適ph和溫度分別為4 . 5和70 ，在ph5 . 0 、 50下對水楊素鈉的米氏常數km為3 . 73mg ml ，最大反應速度vm為0 . 088mg葡萄糖（ ml ? min ） ；與文獻中從黑麴黴中分離的-葡萄糖苷酶比較后發現，該組分是一個新的-葡萄糖苷酶。
  5. The human placental alkaline phosphatase ( hplap ) ( ec 3. 1. 3. 1 ) would be used more widely in molecular biology and elisa for its enzyme activity and heat resistant was higher than that of e. coli alkaline phosphatase ( eap ) and calf alkaline phospha - tase ( c1ap ). it is promising to construct the gene engineering pichia pastoris to product the hplap in a scale for the resource of hplap is limited

    L ）的活性和耐熱性都高於常用的大腸桿菌堿性磷酸酯酶（ eap ）和小牛腸堿性磷酸酯酶（ ciap ） ，因而更適用於分子生物學和酶聯免疫領域，然而其米源受到限制，探討利用畢赤酵母尺屍astorjs構建工程菌進行規模生產鳳有） 』 『闊的前景。
