Anti-biofilm activity of the Antarctic marine bacterium Pseudoalteromonas haloplanktis TAC125.
Considering the increasing impact of bacterial biofilms on human health, industrial and food-processing activities, the interest in the development of new approaches for the prevention and treatment of adhesion and biofilm formation capabilities has increased. A viable approach should target adhesiv...
