The effect of purified PCA4 on wollastonite dissolution (Experiments 4 and 5).

(a) SDS-PAGE analysis of recombination protein (PCA4). The sizes of the protein markers are 116.0, 66.2, 45.0, 35.0 and 25.0 kDa, respectively. (b) Ca2+ concentrations at different sampling times, with or without PCA4 in the reaction system, using a concentration of 0.039% CO2.
