a Remaining calcium concentration in the cultures 5 days after the fermentation began. b Calculated calcium consumption amount (bars) and percentage (plot) based on the samples in (a). c Calcium consumption in the cultures. The experiment shown in (a) was repeated using the higher inoculum size. d Dry weight of pellets collected from cultures grown for 10 days. e An optical image of the SB823 culture. f HAADF-STEM analysis of the SB823 culture. g, h XRD spectra of the dried pellets from the SB760 and SB823 cultures. i Electron diffraction analysis of the product identified in (f). Each dot (a, c, d) represents an individual measurement from a biological triplicate. Bars (a, b, d) and lines (c) indicate the mean values, and error bars represent the standard deviation (a, c, d). Source data are provided as a Source Data file.
