Abstract High hydrostatic pressure (HHP) is the most-widely adopted novel non-thermal technology for the commercial pasteurization of foods. However, HHP-induced inactivation of bacterial spores remains a challenge due to spore resistance to the treatment limits of currently available industrial HHP units (i.e. ∼650 MPa and 50 °C). Several reports have demonstrated that ...

Biofilms are communities of microbes that exist in a variety of environments. The extracellular substances secreted by biofilms make them difficult to eradicate, giving the bacterial community in the biofilm a resistance advantage over freefloating (planktonic) microbes. Biofilms are particularly problematic in chronic wounds because of their resistance to conventional ...
