Catalase incorporation into enumeration media caused a significant increase (greater than 63%) in the colony-forming abilities of airborne bacteria. Incubation for 30 to 60 min of airborne bacteria in collection fluid containing catalase caused a greater than 95% increase in colony-forming ability. However, catalase did not have any effects on enumeration at high relative humidities (80 to 90%).
将过氧化氢酶加入计数培养基中,可使空气传播细菌的菌落形成能力显著提高(超过63%)。在含有过氧化氢酶的收集液中,将空气传播细菌培养30至60分钟,其菌落形成能力提高超过95%。然而,在高相对湿度(80%至90%)条件下,过氧化氢酶对计数没有任何影响。
