说明

一般描述

Tryptic Soy Agar + LT + Cephase - ICR in 90 mm settle plates (non-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 of sterile production. 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 supplying organic nitrogen, particularly amino acids and longer-chained peptides. Sodium chloride maintains the osmotic equilibrium and the medium is supplemented with pyruvate to inactivate residues of hydrogen peroxide. Lecithin and polysorbate 80 (Tween®) are neutralizers to inactive the active agents of disinfectants such as Alcohol (70% ethanol or isopropyl alcohol), Dichloroisocyanurate, Glucoprotamine, Peracetic acid, Phenolic compounds, quaternary ammonium compounds and Biguanides. The combination of a specific broad spectrum cephalosporinase and penicillinase results in the inactivation of β-lactam antibiotics such as penicillins and cephalosporins and enabling efficient growth of microorganismen in the presence of β-lactam antibiotics.

胰蛋白酶大豆琼脂+LT+Cephase-ICR在90 mm沉降板（不可锁定）中设计用于通过主动或被动空气监测以及隔离器和无菌生产洁净室中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，提供有机氮，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，以钝化过氧化氢残留物。卵磷脂和聚山梨酯80（吐温®）是中和剂，可使消毒剂的活性剂失活，如酒精（70%乙醇或异丙醇）、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导致青霉素和头孢菌素等β-内酰胺类抗生素失活，并使微生物在存在β-内酰胺类抗生素的情况下高效生长。

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.
