Examining seawater presents an enduring challenge due to the complexity of molecules present in trace amounts and their dynamic nature. The lowest ecological region of the sea is inhabited by holobionts, such as sponges, which significantly shape the marine chemical landscape through the release of diverse exometabolites. In addressing the need to capture these molecules immediately after release, a novel underwater device was developed, allowing in situ collection and enrichment without harming organisms. To test the device, researchers investigated exometabolites of sponges in the Mediterranean sea using untargeted mass spectrometry and CANOPUS to understand the chemical class distribution. This approach holds promise for studying endangered species in marine protected areas, assessing seasonal variations in exometabolite production, and monitoring toxins or human impacts in the marine environment.

Befriend your competitor: CSI:FingerID identifies metabolite linked to dual-species biofilm pathogenesis in cystic fibrosis
In the world of microbiology, there’s an ongoing battle between different bacterial species competing for survival and dominance. However, under certain conditions, two species can actually thrive together in a dual-species biofilm. The cooperation between P. aeruginosa and S. aureus in cystic fibrosis leads to increased disease severity. But so far, only little is known about the chemical communication mechanisms between those bacteria. CSI:FingerID identifies a metabolite that could be related to the increased pathogenesis of this dual-species biofilm in cystic fibrosis.
