研究专性厌氧菌硫酸盐还原菌混合培养物对偶氮染料、三苯甲烷染料、蒽醌染料的脱色作用.在菌的生长过程中,随着硫化氢的形成,染料的脱色率不断增长.分别测定了完整细胞和上清液对5种染料的脱色能力.当上清液中含有硫化氢时,在1h内不同染料(50mg/L)的脱色率可达25.58%—98.8%;而完整细胞的脱色率则为6.99%—80.60%.由此表明,在厌氧硫酸盐还原条件下,硫酸盐还原菌及其产物硫化氢对染料的脱色均有重要作用.完整细胞对10种结构不同的染料(50mg/L)的半脱色时间为0.5—32.6h,甚至更长,脱色的最适温度和pH分别为30℃和8.0,严格厌氧;还原型烟酰胺腺嘌呤二核苷酸对脱色具有促进作用,粗酶液对酸性红B2GL脱色比活(染料/蛋白)为0.87μg/(mgmin),米氏常数Km值为14mmol/L

The electronic structures of the cyclic nucleotides cAMP and cGMP are calculated by means of the CNDO/2 method. On basis of the computed charge distributions in the mentioned nucleotides and protein kinase has been discussed. The essential part in the interaction perhaps is the sugar-cycli phosphate. The possible actions of bases in regulating the activity of the two nucleotides are also discussed. In addition the action of stabilizing conformation by hydrogen bonds in both nucleotids cAMP and cGMP are analyzed....
