Abstract	We investigated the effects of seawater acidification induced by ocean CO$_{2}$ sequestration on bathypelagic prokaryotes. We simulated acidification conditions by bubbling high-CO$_{2}$ air or adding chemical buffer solutions to seawater samples in order to examine changes in total cell counts, heterotrophic production rate, direct viable cell count, and relative abundance of Bacteria and Archaea. Considerable suppression of prokaryotic activities was observed at pH 7.0 or lower, especially in samples enriched with organic matter. The relative abundance of Archaea increased with increasing CO$_{2}$ concentration. We found that seawater acidification can potentially alter heterotrophic activities and community structure of bathypelagic prokaryotes.
