There have never been more legit online jobs and side hustles. Gigs like answering questions on a paid survey site can be a solid way to make money from home with your smartphone, but go into them knowing that the payout will be limited. Although it’s easy money, you probably won’t earn more than a few hundred dollars per year (at best) by working for these companies. Y O

结果判断:培养液变色为阳性,不变色则为阴性
注意事宜:
1.生物监测结果只有在阳性对照管呈阳性(由紫色变为黄色)时才有效。
2.使用前请确认湿热灭菌生物指示剂的完整性、盖子侧孔未被封闭并使其恢复至室温。
3.请在温度4℃~25℃,相对湿度30%~70%条件下保存,远离灭菌剂,避免日光和紫外线照射,请勿冷冻。

湿热灭菌生物指示剂如何选用?
一般情况下,生物指示剂选择的原则性要求是:孢子稳定、非致病菌、易于培养、有效期长、保存及使用方便、安全性好。针对具体的灭菌工艺和具体的产品,还应注意所用的生物指示剂的耐热性应强于待灭菌产品中的污染菌。
湿热灭菌工艺常用的生物指示剂有以下几种,嗜热脂肪芽孢杆菌,枯草芽孢杆菌,凝结芽孢杆菌,梭状芽孢杆菌等。对于采用过度杀灭法的灭菌程序,生物指示剂系统主要是嗜热脂肪芽孢杆菌的孢子。残存概率法由于其热输入量比较低,因此在验证中使用的生物指示剂的耐热性可以小于嗜热脂肪芽孢杆菌的孢子。
湿热灭菌工艺的验证:
湿热灭菌工艺的验证一般分为物理验证和生物学验证两部分,物理验证包括热分布、热穿透试验,生物学验证主要是微生物挑战试验。物理验证是证实灭菌效果的间接方式,而微生物挑战试验则直接反映灭菌的效果,两者不能相互替代。
