DXB-2型电子保鲜器抑菌作用的观察

OBSERVATION OF BACTERIOSTASIS OF DXB-2 TYPE ELECTRIC KEEPING FRESH APPARATUS

观察DXB-2型电子保鲜器对常见肠道致病菌的抑菌作用．结果显示：保鲜器工作1小时对大肠杆菌、痢疾杆菌、伤寒杆菌均有抑制作用（P＜0．01）；保鲜器工作2小时，对以上细菌的抑制作用增强，并对金黄色葡萄球菌、枯草杆菌也有抑制作用（P＜0．01，P＜0．05）．但保鲜器工作2小时与3小时抑菌作用无差异（P＞0．05）。

The bacteriostasis of DXB-2 type electric keeping fresh apparatus (EKFA) was ob-served. The results showed that EKFA could inhibit growing of Escherichia coli, Clysentery bacteria and Salmonella typhi in 1 hour (P<0. 01 );and increase bacteriostasis on above bacteria and also inhib-it Staphylolcoccal aureus and Bacillus sutilis in 2 hours(P<0. 01, P<0. 05), but bacteriostasis of 2hours comparing with that of 3 hours had no significant difference.
