嗜热脂肪芽孢杆菌抗氧化酶相关性研究

从一些地区的温泉和近热源的土壤以及污水中分离到１０株嗜热脂肪芽孢杆菌，并对其生长量，蛋白含量和抗氧化化酶活力及其电泳图谱特征进行了研究，结果表明，不同菌株的生长量与蛋白一之间呈负相关趋势；ＰＯＤ、ＣＡＴ和ＳＯＤ３种抗氧化酶之间具有密切的相关性，在细胞内组成了一个连锁互补的重要的抗氧化酶体系抗氧化酶活性高的Ｔ９２６菌株表现出具有很高的耐高温的能力。

The Relativity of Antioxidant Enzyme in Bacillus stearothermophilus

Ten strains of Bacillus stearothermophilus from hot spring of some areas and soil near heat source and waste water were separated, the biomass, total protein contents, activity of antioxidant enzyme(catalase, preoxidase and superoxide dismutase)and the pattern of electrophoresis were studied. The results show that there is very close relativity between biomass and contents of protein and among peroxidase,catalase and superoxide dismutase and the three enzymes constitute and important antioxidant enzyme system of mutual compensation in cells of strain. T926 strain of the highest activity of antioxidant enzyme is of very high temperature-resisting.
