Biofilm or bulkhead film? This protein gives bacteria the flick

Researchers from the University of Newcastle, UK, found NucB, an enzyme isolated from Bacillus licheniformis, a marine bacterium found on the surface of seaweed, could disperse the microbial biofilms which prevent antibiotic nasal sprays from working.

Put to work, the enzyme degrades extracellular DNA found in the biofilms, the researchers reported.
