Rude am i in my speech , and little bless ' d with the soft phrase of peace : for since these arms of mine had seven years ' pith , till now some nine moons wasted , they have used their dearest action in the tented field , and little of this great world can i speak , more than pertains to feats of broil and battle , and therefore little shall i grace my cause in speaking for myself 我的言語是粗魯的，一點不懂得那些溫文爾雅的辭令；因為自從我這雙手臂長了七年的膂力以后，直到最近這九個月以前，它們一直都在戰場上發揮它們的本領；對于這一個廣大的世界，我除了沖鋒陷陣以外，幾乎一無所知，所以我也不能用什麼動人的字句替我自己辯護。

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，然后將可變碳源(云杉纖維、玉米芯纖維、麥桿纖維、麥桿木聚糖、玉米芯木聚糖、云杉甘露聚糖)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，并以槐豆膠為底物用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云杉纖維、麥桿木聚糖和云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。
