Assessment of heat resistance of bacterial spores

We defined spore heat resistance as the critical DPA release temperature (T c), the temperature at which half the DPA content has been released within a fixed incubation time. We found T c values for spores from Bacillus strains 168, A163, and IC4 of 108°C, 121°C, and 131°C, respectively.sp.info Assessment of Heat Resistance of Bacterial Spores from Assessment of Heat Resistance of Bacterial Spores from Food Product Isolates by Fluorescence Monitoring of Dipicolinic Acid Release Remco Kort, 1* Andrea C.

The ubiquitous presence of bacterial spore formers in nature can be largely attributed to their ability to produce endospores (spores) that can survive harsh environmental conditions (Nicholson et al., 2000; Setlow, 2006).Bacterial spores can enter the food chain from many different sources, for example via soil, dust, and biofilms (Heyndrickx, 2011).sp.info Spores in dairy – new insights in detection, enumeration
