Marine enzyme can decongest sinusitis

A new nasal spray from a marine microbe will help clear chronic sinusitis, which causes nasal congestion, difficulty in breathing, pain and swelling around your eyes and cheeks. A team of scientists and surgeons from Newcastle University are developing the spray with an enzyme isolated from a marine bug Bacillus licheniformis, found on the surface of seaweed.

Lab experiments showed that the enzyme, called NucB, dispersed 58 per cent of biofilms in chronic sinusitis formed by the marine bug. The biofilm acts as a slimy barrier to protect bugs from sprays or antibiotics, the journal Public Library of Science ONE reports.
