说明

一般描述

Tryptic Soy Agar + LT + Cephase – ICR+ in 90 mm settle plates (lockable) is designed for the determination of the total aerobic microbial count in air via active or passive air monitoring as well as fingerprints of personnel in isolators and clean rooms. It is a complex medium for cultivation and isolation of a wide range of bacteria, yeasts and molds. The formulation of the Soybean Casein-Digest medium contains combination of casein and soy peptones for supplying organic nitrogen, particularly amino acids and longer-chained peptides. Sodium chloride maintains the osmotic equilibrium and the medium is supplemented with pyruvate to provide an efficient neutralization of hydrogen peroxide residues. Lecithin and polysorbate 80 (Tween®) are neutralizers to neutralize the disinfectants containing active agents such as Alcohol (70% ethanol or isopropyl alcohol), Aldehyde, Chlorine, Dichloroisocyanurate, Glucoprotamine, Peracetic acid, Phenolic compounds, quaternary ammonium compounds and Biguanides. The combination of a specific broad spectrum cephalosporinase and penicillinase provides inactivation of β-lactam antibiotics such as penicillins and cephalosporins enabling efficient growth. In addition, the plate model (plus or “+”) is supplied with a lockable lid for safe transport after sampling without the risk of losing the lid. For aerobic incubation the plates should be locked in the “CLOSED” position and for anaerobic or microaerophilic incubation in the “VENT” position.

胰蛋白酶大豆琼脂+LT+Cephase–ICR+在90 mm沉降板（可锁定）中设计用于通过主动或被动空气监测以及隔离器和洁净室人员的指纹来测定空气中的需氧微生物总数。它是一种培养和分离多种细菌、酵母和霉菌的复杂培养基。大豆酪蛋白消化培养基的配方包含酪蛋白和大豆蛋白胨的组合，用于供应有机氮，尤其是氨基酸和长链肽。氯化钠维持渗透平衡，并在培养基中添加丙酮酸，以有效中和过氧化氢残留物。卵磷脂和聚山梨酯80（吐温®）是中和剂，用于中和含有活性剂的消毒剂，如酒精（70%乙醇或异丙醇）、醛、氯、二氯异氰尿酸盐、葡精蛋白、过氧乙酸、酚类化合物、季铵化合物和双胍。一种特殊的广谱头孢菌素酶和青霉素酶的组合可使青霉素和头孢菌素等β-内酰胺类抗生素失活，从而实现高效生长。此外，平板模型（加号或“+”）配有一个可锁盖子，用于取样后的安全运输，且不存在盖子丢失的风险。对于需氧培养，平板应锁定在“关闭”位置，对于厌氧或微需氧培养，平板应锁定在“通风”位置。

应用

Tryptic Soy Agar (TSA, Soybean Casein Digest Agar) is a complex medium for cultivation and isolation of a wide range of bacteria, yeasts and molds. The media finds its application in environmental monitoring by determining the total aerobic microbial count in air through active or passive air monitoring as well as fingerprints of personnel in isolators and clean rooms.
