Wastewater bacteria can break down plastic for food
Researchers have discovered how cells of a Comamonas bacterium break down plastic for food. First, they chew the plastic into small pieces, then secrete an enzyme that breaks down the plastic further, and finally use a ring of carbon atoms as a food source.

Researchers unravel mystery of dormancy in food pathogens for more effective elimination
The detection tests commonly used to check for the absence of microbes in hospitals or the agri-food industry are based on microbial growth, i.e. the laboratory cultivation of microorganisms from a sample to be checked. If no micro-organisms appear during culturing, the sample is considered safe. Source: INRAE ...
