Biodiversity in Antarctic soils may be greatly underestimated after surprising discovery

Researchers used high-throughput DNA sequencing to measure biodiversity along a transect – a succession from recently exposed to mature soil – in front of a glacier in Antarctica. To capture a detailed ecological ‘time sequence’ they distinguished between intracellular and extracellular DNA from living versus dead or locally extinct species. They found an abundance of previously unsuspected interactions between eukaryotes and prokaryotes, eg, algae with heterotrophic bacteria and fungi with actinobacteria. The results imply that novel mutualistic interactions play an essential role in shaping this system, and that biodiversity in Antarctica may be much greater than previously thought.

Dangerous bacteria lurk in hospital sink drains, despite rigorous cleaning

Researchers from Spain sampled sink drains from different wards in a single modern university hospital where state-of-the-art cleaning protocols are adhered to. Through culturing and DNA barcoding, they found 67 species of bacteria. These included Klebsiella, Enterobacter, and Pseudomonas aeruginosa, notorious for their potential to cause healthcare-associated infections. Several strains detected proved resistant to modern antibiotics, including cephalosporins and carbapenems. Sink drains thus appear to function as reservoirs for known and emerging pathogens of concern.

Promising antibiotic candidates discovered in microbes deep in the Arctic Sea

Researchers from Finland and Norway developed a new suite of methods for the screening of antivirulence activity of unknown compounds of bacterial origin. The compounds tested had been derived from actinobacteria living inside invertebrates in the Arctic Sea. They found two interesting compounds with strong antivirulence or antibacterial effects against enteropathogenic E. coli. These results demonstrate the potential of prospecting novel habitats for promising new antibacterial drugs, to solve the current global antibiotics crisis.

Microbes conquer the next extreme environment: your microwave

Researchers have measured the diversity of microbes inside microwaves for the first time. They showed that microwaves harbor a specialized community of locally adapted microbial genera, which resembles that reported on kitchen surfaces and in another extreme, highly irradiated habitat: on solar panels. This finding has potential biotechnological applications, in processes that require microbes resistant to thermal shock, radiation, and desiccation.
