It is the optimal time for subjecting creatine to the medium when cultured to 12h and the concentration of creatine was 0. 75 %. creatine, sarcosine and choline chloride could induce the creatinase production and creatine was the optimal inducer, but creatinine and urea could not induce the creatinase production. 3 purification of creatinase the process of creatinase purification was performed as follows : first the enzyme was completely precipitated in the range of 40 - 80 % of saturation with ammonia sulfate fraction precipitation
最佳氮源為玉米漿和蛋白腖，最佳比例為2 ： 3 ，最佳濃度為1 . 6 ；加入其它碳源時有助於菌株穩定產酶； 100ml搖瓶的最佳裝液量為15ml ；肌酸、肌氨酸和氯化膽堿都能誘導菌株產酶，其中肌酸誘導產酶的效果最好，而肌酐和尿素不能誘導菌株產酶；誘導物肌酸的最適加入時間為接種培養12小時后，最適加入量為0 . 75 。The paper studied three aspects of extracelluar enzymes in sediments of the tidal flat wetland, namely 1 ) the distibution of five sorts of extracellular enzymes in sediments in the east end of chongming island along the elevation gradient or community succession series, the relationships between the activities of enzymes and the ecological factors, and functions of extracellular enzymes in the process of community succession ; 2 ) the effects of the heavy metal ions and edta on the activity of alkaline phosphatase in sediments of the east end of chongming island by adding and removing of heavy metal ions, discussing whether the activities of extracellular enzymes could be taken as the indicators for the environmental status ; 3 ) the variations of the activities of extracellular enzymes in sediments in the east end of hengsha island after the discarding clay
本文以長江口典型濕地?崇明東灘為例，首次研究了沿高程梯度或沿植被演替系列沉積物中堿性磷酸酶等五種胞外酶活性的空間分佈規律，分析了胞外酶活性與環境因子的相互關系及其產生機制，討論了胞外酶活性在濕地植被演替中的作用。同時以崇明東灘沉積物為對象，運用重金屬離子的添加和去除等方法，研究了重金屬離子對沉積物中堿性磷酸酶活性的影響，利用胞外酶活性的變化探討了崇明東灘重金屬污染的狀況。此外，本文還研究了橫沙東灘吹泥試驗工程對沉積物環境因子和胞外酶活性的影響並進行了對比分析。According to the experiment of alkaline baring and degradation, it is indicated that fungus has better degradation ability, and the mixed bacteria in proportion of 1 : 3 has the best function
根據菌種的耐堿度實驗和降解力實驗，表明真菌的降解能力相當強，而按1 : 3比例配成的混合菌種降解效果最好。The highly exploited region possesses various and equal landuse types, and the proportion of all kinds of landscape types converge, and possess small landscape dominance
開發利用程度較高的綠洲區，土地利用趨于多樣化和均勻化，各類景觀類型比例相差不大，景觀優勢度小，但景觀中因人為活動造成的退化景觀類型如鹽堿地和沙地裸地佔有較大的比例。分享友人
