微生物鑑定測試及生化試劑
用於微生物鑑定或區分生物群組的生化、免疫和分子生物學測試,經常被用於生產設施和學術研究中的微生物品質控制。此類微生物鑑定測試可檢測特定蛋白質、目標細胞的某些生化活動(例如酵素的活動)或微生物特有的基因序列。許多微生物鑑定測試可在短時間內提供重要的結果,而且非常經濟實惠、使用方便,大多不需要特定的設備或儀器。有些生化檢測只需要滴一滴試劑在瓊脂平板或液體培養基。
用於鑑定的生化試劑
生化試劑是液體生化測試的基礎,用於檢測目標微生物特有的酶活性等。
顯微鏡試劑& 套件
染色微生物的試劑和套件用於在顯微鏡下區分和鑑定這些微生物。
微生物測試套件
測試套件基於不同的方法,包括生物化學和免疫學方法。例如,可透過可見的凝固、顏色反應或渾濁度來評估結果。
HybriS可® 原位雜交
先進的微生物鑑定系統HybriScan® 是一種快速分子生物學測試,用於準確檢測和識別飲料、水和食品中的腐敗和致病微生物。它以探針原位雜交為基礎。
碟片、條狀試劑和識別膜
碟片、條狀試劑和 ID 膜是基於生化試劑和反應的多種用戶友好型微生物識別測試形式之一。這些試劑浸漬在例如紙張等載體上,因此既穩定又容易處理。一個著名的例子是氧化酶條,用來檢查細胞色素氧化酶的活性。

Beer-spoiling microorganisms cause an increase of turbidity and unpleasant sensory changes in beer. Since the improved process technology in modern breweries has resulted in signifi cant reduction of oxygen content in the fi nal product, the role of strictly anaerobic bacteria like Pectinatus and Megasphaera has increased.
