We describe a one-dimensional probabilistic model of the role of domestic food handling behaviors on salmonellosis risk associated with the consumption of eggs and egg-containing foods. Six categories of egg-containing foods were defined based on the amount of egg contained in the food, whether...

The foodborne disease risk associated with the pathogen Listeria monocytogenes has been the subject of recent efforts in quantitative microbial risk assessment. Building upon one of these efforts undertaken jointly by the U.S. Food and Drug Administration and the U.S. Department of Agriculture...

Microbial necromass has been increasingly recognized as an important source of soil organic carbon (C). However, how nitrogen (N) addition regulates microbial necromass decomposition and the size of different necromass pools remain poorly understood. Here, via an incubation of 13 C-labeled...

For the treatment of nitrogen-containing sewage and wastewater, denitrification embedded immobilized filler show high nitrogen removal performance and stability, but the cultivation of a large number of compound denitrifying bacteria needed for embedding immobilization requires a huge...
