Mapping the molecules made by a lichen's resident microbes

An international team of researchers has spatially mapped molecules produced by an intact, complex microbial community for the first time. Using a tiny slice of lichen, the team used imaging mass spectrometry to track and ...

Precut salad may encourage growth of Salmonella

A new study from the University of Leicester shows that small amounts of damage to salad leaves in bagged salads encourage the presence of Salmonella enterica. Juices released from damaged leaves also enhance the pathogen's ...

What happens to a pathogenic fungus grown in space?

A new study, published this week in mSphere, provides evidence that Aspergillus fumigatus, a significant opportunistic fungal threat to human health, grows and behaves similarly on the International Space Station compared ...

Metagenomic study links microbes to flavors in kefir

A team of food scientists and microbiologists in Ireland have used high-throughput sequencing to analyze how microbial populations change as kefir ferments. It's a new frontier in food analysis: Using the data, collected ...

Antimicrobial resistance gene found in marine pathogen

A team of Chinese investigators has discovered a gene for resistance to β-lactamase antibiotics, in the pathogenic marine bacterium, Vibrio parahaemolyticus. The β-lactamase gene, blaVEB-2, has never before been found in ...

Protein synthesis, ATP unnecessary for bacterial spore germination

Spores of Bacillus bacteria can survive for years in a dormant state, and then germinate in minutes. But it has long been unclear whether germination required protein synthesis, or cellular energy packets, which are known ...
