Diversity of lake bacteria promotes human echovirus inactivation

Applied and Environmental Microbiology
Human enteric viruses can remain infective in surface waters for extended periods of time, posing a public health risk. Microbial activity contributes to the inactivation of waterborne enteric viruses, but while individual bacteria–virus interactions ...

Microbial Inactivation by Ultrasound Assisted Supercritical Fluids [PDF]

Physics Procedia, 2015
A method combining supercritical carbon dioxide (SC-CO2) and high power ultrasound (HPU) has been developed and tested for microbial/enzyme inactivation purposes, at different process conditions for both liquid and solid matrices. In culture media, using only SC-CO2, the inactivation rate of E. coli and S.

Instrument for Study of Microbial Thermal Inactivation [PDF]

Applied Microbiology, 1968
An instrument was designed for the study of thermal inactivation of microorganisms using heating times of less than 1 sec. The instrument operates on the principle of rapid automatic displacement of the microorganism to and from a saturated steam atmosphere, and the operating temperature range is 50 to 90 C.
