摘要
从污染的土样中分离到一株高效降解3,5-二硝基水杨酸的菌株E-2,它能够在以3,5-二硝基水杨酸为唯一碳源和能源的无机培养基上生长。根据菌株E-2的形态特征及生理生化反应特征,初步鉴定为盐芽孢杆菌属(Halobacillus Spring et al.)。研究表明:此菌能以3,5-二硝基水杨酸为唯一碳源进行生长,最适合浓度为0.05%,pH值为8.0,温度为30℃,培养5天后降解率为85%。
strain E- 2 that was able to degrade 3,5 - Dinitrosalicylic acids was isolated from the contaminated soil.It could grow with 3,5- Dinitrosalicylic acid as the sole source of carbon and energy,and it was identified as Halobacillus Spring et al. According to its shape characteristics, its physiological characteristics and biochemical characteristics, our study indicates that the stain could grow with 3,5 - Dinitrosalicylic acid as the sole source of carbon and the rnost perfect concentration is 0.05 %, the pH is 8.0, and the temperature is 30 degrees centigrade, and after 120 hours of aerobic cultivation in shaking flack.
