氨基酸的氮成分未被導入確定的代謝順序中去。Whole cell c2d2 reduction by all four mutants comparing to wild type and ni / v mutant was also detected. the result showed that only single a - gln194 substitution did not perturb the stereospecificity of protonation of c2d2. the above comparing results indicate that in mofe protein ( 1 ) a a - gln190 site and its association with homocitrate are important for the transfer of electron / proton to femoco, while a - his194 site and the homocitrate are independent in h2 evolution
對四個突變株細胞的c _ 2d _ 2還原特性及還原產物中反式-順式- 1 ， 2 -二氘代乙炔的比例進行了測定並與野生型及nifv突變株相比較，結果表明只有- gln ~ （ 194 ）替換不影響c _ 2d _ 2還原產物中反式-順式- 1 ， 2 -二氘代乙炔的比例，即未改變固氮酶還原c _ 2h _ 2加氫的立體構型的專一性。The soil physical composition, organic matter, total nitrogen, total phosphorus, total potassium and ph of salix psammophila ccheckerboard and contrast sand of dalate county were investigated in 2005, the effects of salix psammophila checkerboard on physical and chemical characteristics of sandy soil were analyzed
摘要本試驗於2005年在達拉特旗測定了設置沙柳沙障的沙丘和對照樣地（未設沙障）的土壤機械組成、有機質、全氮、全磷、全鉀、酸堿度等理化指標，對比分析沙柳沙障對土壤理化性質的影響。The protein in crude rice underwent no denaturation or gelatine because it never suffered from any hot and humid actions, which was a determinant factor of malt yellow rice wine features ( rich nitrogen amino acid )
生大米中的蛋白質，因未受濕熱作用而變性或膠凝化，決定了免蒸煮麥曲黃酒氨基酸態氮豐富的產品營養特徵。We took atrazine and metsulfuron - methyl as examples to evaluate their dynamics of degradation in soils and the responses of microbial biomass after application of organic matters and fertilizers. the objectives are to find out the relationship among of organic matters / fertilizers added, microbial biomass and herbicides degradation, and for remediation of soils contaminated by herbicides. the main results were summarized as follows : effect of organic matters and fertilizers on microbial biomass in soils contaminated by atrazine / metsulfuron - niethyl herbicides ( l ) the contents of soil microbial biomass c, n and p significantly decreased after application of atrazine at the rate of 22
與空白對照相比，在淡塗泥田中微生物生物量碳、氮、磷分別平均降低了12 . 37 、 11 . 79和11 . 94 ；在青紫泥田中分別平均降低了10 . 70 、 8 . 43和13 . 66 ；在黃筋泥田中分別平均降低了8 . 55 、 11 . 95 （因其酸度較低，微生物生物量磷的測定方法與前兩種土壤的不同，所以未測定其中的微生物生物量磷的含量） 。Denitrification and nitrogen fixation in 10 cm 20 cm horizon are higher than those in other soil horizons, in which the partial pressure of oxygen is lower than that in surface horizon, and the number of microorganisms is more than that in below horizon
