D. WATIER, I. LEGUERINEL, J.P. HORNEZ, I. CHOWDHURY AND H.C. DUBOURGUIER. 1995. The heat resistance of three strains of Pectinatus (Pectinatus cerevisiiphilus DSM 20466, Pectinatus sp. DSM 20465 and Pectinatus frisingensis ATCC 33332) were measured at different temperatures (50–60°C), different pH (4–6·3), in two media (MRS and wort). Similar D60 values were obtained for DSM 20465 and ATCC 33332, but DSM 20466 was more resistant in MRS. Moreover the z values were higher in MRS than in wort for the three strains. Thermal destruction at different pH was variable. Results were discussed in relation to factors affecting heat resistance. |
