Impacts of UV-C Irradiation on Marine Biofilm Community Succession.

ABSTRACT: Marine biofilms are diverse microbial communities and important ecological habitats forming on surfaces submerged in the ocean. Biofilm communities resist environmental disturbance, making them a nuisance to some human activities ("biofouling"). Antifouling solutions rarely address the underlying stability or compositional responses of these biofilms. Using bulk measurements and molecular analyses, we examined temporal and UV-C antifouling-based shifts in marine biofilms in the coastal western North Atlantic Ocean during early fall. Over a 24-day period, bacterial communities shifted from early dominance of Gammaproteobacteria to increased proportions of Alphaproteobacteria, Bacteroidia, and Acidimicrobiia. In a network analysis based on temporal covariance,
