Pulsed electric field (PEF) processing has been developed for the inactivation of microorganisms in liquid foods at low to moderate temperatures. The efficiency of microbial decontamination by PEF is largely dependent on the applied electric field strength, exposure time and treatment temperature. Thus, detailed knowledge of the distribution of these process parameters is essential for successf...

An incubation experiment was conducted to study the effect of clay content and composition on organic nitrogen mineralization. The measured mineralization from alfalfa residues, enzyme activities, microbial biomass in mixtures sand, kaolinite, non-layered colloids (NLCs) with sand as a control. found that contents kaolinite NLCs increased, activity decreased, but increased. maximum decrease 88....

During the last decade an increased incidence of infections and outbreaks attributed to foodborne viruses, in particular noroviruses (NoV), was observed world wide. The awareness of the presence of viruses on food emphasized the need to acquire knowledge regarding the effect of preservation methods upon viruses. Most foodborne viruses cannot be cultured in the laboratory, which hinders studies ...

Pulsed electric field (PEF) is an innovative non-thermal technology which could be used as an alternative to the traditional thermal process to inactivate the microorganisms and enzymes in liquid foods such as milk. Compared to thermal processing, the PEF process is considered more energy efficient as the microbial or enzymatic inactivation is achieved at ambient or mild temperatures by the app...

1. Better bacterial inactivation was observed with higher ultraviolet (UV) doses. There is a need for better tank configuration (hydraulic performance) to ensure proper water circulation or a need to suppress microbial recovery. Addition of titanium dioxide (TiO2) during UV irradiation was effective in controlling microbial recovery. 2. Higher water temperature enhanced the fouling rate on quar...

Despite numerous examples of the effects of the human gastrointestinal microbiome on drug efficacy and toxicity, there is often an incomplete understanding of the underlying mechanisms. Here, we dissect the inactivation of the cardiac drug digoxin by the gut Actinobacterium Eggerthella lenta. Transcriptional profiling, comparative genomics, and culture-based assays revealed a cytochrome-encodin...

Abstract Pulsed electric fields (PEF) as a new pasteurization technology played an important role in the process of inactivating microorganisms. At same time, temperature could promote electroporation, and achieve better inactivation effect. This article studied effect PEF on Saccharomyces cerevisiae , Escherichia coli Bacillus velezensis under different initial temperatures (room temperature-2...
