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。
