Scaling-up the co-culture of Ulva ohnoi with Phaeobacter bacteria

This research aimed to examine the potential of using U. ohnoi colonised with Phaeobacter sp. 4UAC3, previously isolated from natural populations of Ulva australis, as a strategy to prevent vibriosis in fish cultured in IMTA-RAS systems. Phaeobacter sp. 4UAC3 colonization and maintenance on U. ohnoi was studied in a re-inoculation scale-up process from multi-well plates (10 mL) to flasks (4 L) and finally to tanks (40 L).
