CALCIFICATION BY COCCOLITHOPHORIDS: EFFECTS OF pH AND Sr<sup>1</sup>
Abstrak
ABSTRACTCells of Coccolithus huxleyi which fail to deposit CaCO3 and form coccoliths often occur as unwanted components in cultures used for studies of calcification. Non‐calcified cells generally cannot be made to recalcify, but they can be removed from cultures by treatment at elevated pH or by a method based on faster sinking of calcified cells. Lowering the concentrations of nitrate, phosphate, or trace metals in the medium did not restore calcifying ability of non‐calcified cells. However, addition of strontium did promote recalcification of decalcified Cricosphaera carterae grown under calcium limitation. Strontium seemed to promote coccolith attachment to cells rather than to affect calcium uptake or coccolith formation itself.
