For isolation of environmental mycobacteria, a decontamination procedure has been standardized by which treatment with 3% sodium dodecyl sulfate plus 4% NaOH (15 and 30 min for rapid and slow growers, respectively) is followed by incubation with 2% cetrimide (5 and 15 min for fast- and slow-growing mycobacteria, respectively); this procedure was found to completely eliminate contamination with other organisms and resulted in the isolation of only mycobacteria.
为了分离环境中的分枝杆菌,已制定了一种去污程序,即先用3%十二烷基硫酸钠加4%氢氧化钠处理(快速生长菌和缓慢生长菌分别处理15分钟和30分钟),然后用2%溴化十六烷基三甲铵孵育(快速生长和缓慢生长的分枝杆菌分别孵育5分钟和15分钟);该程序被发现能完全消除其他微生物的污染,仅分离出分枝杆菌。
