Modelling combined effects of temperature and pH on the heat resistance of spores ofBacillus cereus

Characterization of Bacillus cereus spores isolated from Algerian processed cheese

“…The result suits those quoted by Lopez et al (1997) and Couvert (1999). The obtained ZpH=3.58 value was close to ZpH reported by Gaillard et al (1998). They record a 4.08 ZpH value for a pH range of 4.5 to 6.6 with a constant temperature.…”

Modelling the overall effect of pH on the apparent heat resistance of Bacillus cereus spores

“…cereus was close to 7.5 (Gaillard et al, 1998). The model was then fitted with pH* = 7.5 according to a linear regression (table 2).…”

The growth, physiology and toxigenic potential of Bacillus cereus in cooked rice during storage temperature abuse

“…Endospore-free suspensions of vegetative cells were prepared using a double-pass method and harvesting cells during the early exponential phase prior to the appearance of endospores (Clavel, Carlin, Lairon, Nguyen-The, & Schmitt, 2004). Pure suspensions of endospores were generated according to the method of Gaillard, Leguerinel, and Mafart (1998). This procedure yielded endospore suspensions of >95% purity in terms of phase bright bodies when examined using a phase contrast microscope.…”
