AbstractThe cosmopolitan alga Phaeocystis globosa forms massive colonies during blooms. In addition to producing haemolytic toxins that affect the ecosystem, centimetre-sized colonies can block nuclear power plant cooling systems. Nitrogen plays a key role in P. globosa blooms; however, the preferred form of inorganic nitrogen taken up by colonies remains unknown. Therefore, we set up four groups with different nitrogen types and levels of enrichment. The culture medium and intracolonial fluid were sampled at different times for the determination of nutrient concentrations to elucidate the nutrient uptake strategy that presumably favours colonies. Although NH4+-N and NO2--N were absorbed by the colonies, NO3--N was the favoured nitrogen, and the average uptake rate of NO3--N was significantly higher than that of NH4+-N and NO2--N in each group (P<0.05). In the enriched groups, the replenishment of NO3--N in the intracolonial fluid was faster than that of NH4+-N. The symbiotic bacteria and some biochemical processes may explain the differences in the nutrient concentrations inside and outside of the colonies. Considering the high consumption of NO3--N during P. globosa blooms, controlling the concentration of NO3--N is key to preventing P. globosa blooms.
