Phaeobactergrown in biofilters: a new strategy for the control ofVibrionaceaein aquaculture

Growth, biofilm formation, antagonism and residence time in green seawater tanks maintained under fish rearing conditions of Phaeobacter 27-4 were studied in commercial biofilters made from plastic, sintered glass and ceramic. Phaeobacter reached 108–109 CFU cm−3 and formed rosettes in all materials, but a multilayer biofilm was only observed in the ceramic biofilters. In sterile seawater, plastic and ceramic biofilters reduced Vibrio...
