Effect of Sodium Chloride Concentration in an Agar Medium on Growth of Heat-Shocked Staphylococcus aureus

摘要: The numbers of Staphylococcus aureus 196E surviving heat treatment in milk for various times at 60 C were determined by plate count with normal and modified Medium No. 110 (S-110), Plate Count Agar (PCA), enrichment techniques. Portions specific heated samples appeared to contain lower populations S. when the survivors enumerated S-110 than PCA. Similarly, needed total destruction culture suspension test be shorter survival was agar. apparently thermal death found related NaCl content medium, because use agar containing lesser concentrations resulted growth larger heat-shocked 196E.
