New insights into Saccharomyces cerevisiae induced calcium carbonate precipitation.

ABSTRACT: Our previous study reported that Saccharomyces cerevisiae could induce calcium carbonate (CaCO₃) precipitation, but the associated mechanism was unclear. In the present study, Saccharomyces cerevisiae was cultured under various conditions, including the presence of different organic acids and initial pH, and the yields of CaCO₃ formation induced by the different organic acids were compared. The metabolism of organic acid by the metabolites of S. cerevisiae was also assessed in vitro. The SEM-EDS and XRD results showed that only acetate acid, pyruvic acid, and α-ketoglutaric acid could induce CaCO₃ formation, and the weight order of the produced CaCO₃ was pyruvic acid, acetate acid, α-ketoglutaric acid. In addition, the
