详细内容
操作方法
(5)用右手的无名指、小指和手掌将菌种管和待接斜面试管的棉花塞或试管帽同时拔出,然后让试管口缓缓过火灭菌(切勿烧过烫)。
(6)将灼烧过的接种环伸入菌种管内,接种环在试管内壁或未长菌苔的培养基上接触下,让其充分冷却,然后轻轻刮取少许菌苔,再从菌种管内抽出接种环。
(7)迅速将沾有菌种的接种环伸入另支待接斜面试管。从斜面底部向上作“Z”形来回密集划线。有时也可用接种针仅在培养基的中央拉条线来作斜面接种,以便观察菌种的生长特点。
(8)接种完毕后抽出接种环灼烧管口,塞上棉塞。
产品简介
微生物限度检测仪装置,三联微生物限度检测仪厂家:QYW-300B微生物限度检测仪(微生物薄膜过滤器)采用不锈钢金属材料制成,配有内置隔膜液泵,不需外接抽滤瓶,液体直接通过隔膜液泵排除,减少了抽滤瓶使用上的繁琐,避免了连接不好造成抽滤速度慢等缺点。
微生物限度检测仪装置,三联微生物限度检测仪厂家:将供试品注入微生物限度培养器内,通过检验仪自带内置隔膜液泵负压抽滤,将供试品中微生物截留在滤膜上,用取膜器取出滤膜,转移至配置好的固体培养基上,菌面朝上,平贴。盖上盖子形成封闭的培养盒,置于相应的恒温培养箱内培养并计数。
制药:纯化水、注射用水、眼用制剂、原料药、胶囊、生物制品、片剂、口服制剂;
食品:纯净水、矿泉水、饮料;
化工:各种需测试微生物水样;
化妆品:各种用水及产品;
控疾:江、河、湖、海、水样。

公司介绍
Abstract: Microbial contamination is one of the main forms of exogenous contamination in Chinese sliced decoction pieces, and it is also an important way to affect human health. The research progress of microbial contamination and typical bacteria in prepared slices in recent 10 years was reviewed, the results showed that the microbial contamination in prepared slices in China was serious, the microbial contamination among different varieties, sources and processing methods was quite different, the contamination rate of heat-resistant bacteria and bilia-tolerant gram-negative bacteria was high, and the detection rate of other control bacteria was low. Studies on the isolation and identification of typical contaminated bacteria mainly focus on heat-resistant bacteria and gram-negative bacteria.
