- acetolactate decarboxylase is purifed from cell extract by 50 % - 80 % ammonium sulfate - fractionation, 50, 2min heat treatment and deae - sepharose fast flow column chromatography, which we study the different ph and different buffer of deae - sepharose fast flow column chromatography and conclude ph 6
對其酶學性質進行了研究。 -乙酰乳酸脫羧酶經50 80硫酸銨分級沉澱、 50 ， 2min熱處理、 deae - sepharosefastflow離子交換柱層析方法分離純化。 -
- acetolactate decarboxylase are widely found among bacterial strains but not in other groups of organisms. the enzyme has been demonstrated to be effective for removal of acetolactate and widely used in beer product. in this paper, - acetolactate decarboxylase from bacillus subtilis was purifed to homogeneity from cell extract by ammonium sulfate - fractionation, heat treatment, deae - sepharose fast flow column chromatography
本文對來源於枯草芽孢桿菌（ bacillussubtilis ） 3226 - 5的-乙酰乳酸脫羧酶經硫酸銨分級沉澱、熱處理、 deae - sepharosefastflow離子交換柱層析等分離純化步驟，得到sds - paeg電泳純，通過n末端氨基酸序列分析驗證酶蛋白的純度。 -
Without ammonium sulphate fractionation and dialysis, the supernatant of crude extract was directly loaded on deae - sepharose cl 6b column equilibrated by phosphate buffer ( 50mmol / l, ph7. 8 ), and the enzyme fraction was not absorbed on the column but impurities were absorbed
粗酶液無需硫酸銨沉澱及透析，即可引入磷酸緩沖液（ 50mmol l ， ph7 . 8 ）預平衡的deae - sepharosecl6b柱，上柱後用平衡緩沖液洗至基線穩定。 afpga不被吸附而直接流出。 -
The enzyme was purified from cell extract by ammonium sulfate fractionation ( 30 % - 80 % saturation ) and consecutive column chromatography using deae - cellulose and sephadex g - 100. the sod activity for purified enzyme could reach 4966 iu / mg proteins, and the molecular weight of the sod was about 20 kda which determined by sds - page electrophoresis. when the non - denaturing polyacrylamide gel stained with substrate for sod in the present of 0. 2mmol / l kcn or 0. 5 mmol / l h2o2, the active band was still showed at the same position, which indicated the sod could not be inhibited by the treatments with kcn or h2o2 and it was the mn sod
通過sds一聚丙烯酸胺凝膠電泳可知該sod酶的分子量約為20kda .在非變性聚丙烯酞胺凝膠（ pagb ）電泳后，在凝膠son顯色反應液中加入0 . 2耐01 / lkcn或0 . 5inmol / lh202 ，凝膠sod顯色反應后在原來的sod酶部位仍然含有sod活性帶，這表明利用kcn和h20 :處理並不能抑制500的活性，該sod屬于mn一sod 。 -
In order to determine the influence of environmental variations on phosphorus removal mechanisms in a combined pond - wetland system, the dominant removal mechanisms of phosphorus in different treatment unit and their influence on phosphate transformation between sediment and water column were investigated through analyzing the differences of phosphorus fractionation with water conditions
摘要為確定環境差異對磷去除機制影響，利用組合塘濕地生態處理系統中各單元環境與磷形態分佈的差異，分析各單元磷的主導去除機制及其對底泥和水體中磷遷移過程的影響。
