Abstract
Heat-treated cultures of Pseudomonas fluorescens, P. fragi, and P. putrefaciens did not grow as readily on plates during the early phase of incubation time as the non-heated cultures. This phenomenon was more pronounced at high (35, 32[degree]C) and low (5[degree]C) incubation temperatures than at a plate incubation temperature of 25[degree]C. Heat-treated survivors were much more sensitive to the pH of the plating medium than the non-heated cultures.This publication has 6 references indexed in Scilit:
