Oyster was hydrolysed with six kinds of commercial proteinases including pepsin, trypsin, bromelin, papain, 3942 neutral proteinase and Alcalase 2.4L. Three enzymes of better hydrolysis effect were chosen as the target enzymes, taking the α-amino nitrogen in the hydrolysates as the index. The hydrolysis conditions of the three enzymes were investigated by single factor experiment and orthogonal test.

Although there were different influences on these soil enzymes for different metals, it was difficult to find a special soil enzyme to index a single heavy metal pollution in soil. Also, little was known about the interwork of heavey metals, soil enzymes and soil conditions. Therefore, lots of research will be needed to accomplish the foundation of enzymes indexes for assessing heavy metals pollution in soil.

雖然不同重金屬元素對(duì)土壤酶活性的影響差異較大，但很難用某一專有土壤酶來(lái)反映特定重金屬的污染想要免费毛片A，而且關(guān)于酶系統(tǒng)與重金屬以及土壤自身和外界環(huán)境因素的相互作用機(jī)制尚不清楚女生被操免费网站，所以土壤重金屬酶學(xué)指標(biāo)的建立還需做大量的研究工作。

Skatole is harmful to human animals as well as environment. When human and animals take food which contains skatole or can be converted into skatole, skatole will inevitably interact with digestive enzymes. Skatole absorbed through skin may also interact with digestive enzymes in human and animals. So we studied the effect of skatole on three important digestive enzymes.

The major results of this proposal are as follows:(1) ABA induces a rapid, substantial accumulation of apoplastic H2O2 in mesophyll and bundle sheath cells of maize leaves, and the accumulation of apoplastic H2O2 is involved in the induction of the chloroplastic and cytosolic antioxidant enzymes.(2) ABA-induced H2O2 production activates a 46 kDa MAPK, which in turn induces the expression of antioxidant genes and up-regulates the activities of antioxidant enzymes. The activation of MAPK also enhances H2O2 production, forming a positive amplification loop.(3) Water stress also induces the activation of a 46 kDa MAPK, which is dependent on the accumulation of ABA and H2O2 production induced by water stress and involved in the up-regulation of the expression and the activities of antioxidant enzymes.(4) ABA-induced H2O2 production mediates NO generation, which in turn activates a 46 kDa MAPK and results in the up-regulation in the expression and the activities of antioxidant enzymes in ABA signaling. NO-independent signaling is also involved in ABA- and H2O2-induced antioxidant defense.

The effect of the flight on the activities of energy metabolism related enzymes in the flight muscles of the Oriental armyworm moth, Mythimna separata females was studied. These enzymes measured were glyceraldehydes-phosphate dehydrogenase, glycerol-3-phosphate dehydrogenase, lactate dehydrogenase, and 3-hydroxyacyl-CoA dehydrogenase. In the first 5 min of the tethered-flight of 3 day-old moth, activities of all the enzymes related to carbohydrate and lipid metabulistu increased rapidly, enzymes related to lipid metabolism were completely activated, and the activities of HOAD were significantly strengthened. But in flight duration from 5th to 60th min, the activities of all energy metabolism related enzymes decreased, suggesting that the flight was going to be stabilized.
