Previous space research conducted during short-term flight experiments and long-term environmental monitoring on board orbiting space stations suggests that the relationship between humans and microbes is altered in the crewed habitat in space. Both human physiology and microbial communities adapt to spaceflight. Microbial monitoring is critical to crew safety in long-duration space habitation ...

Dense Phase Carbon Dioxide (DPCD) is a non-thermal process that pasteurizes mostly liquid foods. It inactivates vegetative bacterial cells, some spores, yeasts and molds, some viruses, and some enzymes. The traditional approach to develop a DPCD process for a new product involves a complex experimental plan to investigate microbial and safety effects. Recent studies show the importance of the s...

Millennium Development Goal Target 7c (to halve between 1990 and 2015 the proportion of the global population without sustainable access to safe drinking water), was celebrated as achieved in 2012. However, new studies show that we may be prematurely celebrating. Access to safe drinking water may be overestimated if microbial water quality is considered. The objective of this study was to exami...

The human food chain, from the raw materials to the human gut microbiota, can be regarded as a sequence of intercom-municating macro-and micro-ecosystems inhabited by more or less specialized microbial populations or consortia. The dynamics of development or selection of these different populations or individual species, including pathogens, spanned along the entire chain, as well as the effect...

background and objectives: sodium nitrite and potassium nitrite have been traditionally used for inhibition of clostridium botulinum and also as an agent to stabilize the color of meat products; however, usage of these additives at high levels could lead to toxicity and cancer originating from the formation of nitrosamines. nowadays, application of natural preservatives in order to reduce the n...

The climate crisis is one of the biggest challenges for humanity in 21st century. Production and consumption meat contributes to global warming by causing emissions climate-relevant gases. Freshly grown sprouts are part an alternative, as they less polluting but still a nutritious food. However, warm humid sprouting conditions may cause pathogenic microorganisms thrive. Decontamination methods ...
