Abstract Calcareous foraminifera are well known for their CaCO 3 shells. Yet, CaCO 3 precipitation acidifies the calcifying fluid. Calcification without pH regulation would therefore rapidly create a negative feedback for CaCO 3 precipitation. In unicellular organisms, like foraminifera, an effective mechanism to counteract this acidification could be the externalization of H + from the site of calcification. In this study we show that a benthic symbiont-free foraminifer Ammonia sp. actively… CONTINUE READING
