Figure Lengend Snippet: The effect of different Ca 2+ concentrations on CaCO 3 mineralisation. (a) The biomineralisation efficiency and amount of biogenic CaCO 3 . (b) The OD 600nm of the bacterial culture at different amounts of added CaCl 2 after 7 days. (c) The precipitated reaction phenomenon after adding 5% HCl. (d) XRD results for the precipitate of different doses of CaCl 2 . V: vaterite, ICDD pdf no. 72-0506. Data represent mean ± s.d. of three independent experiments.

Article Snippet: The TGA results show that, the calcium carbonate induced by the bacteria undergoes a mass-loss stage caused by organic matter combustion (within the range of 209–579 °C), compared to AR (Analytical Reagent)-CaCO 3 (purchased from Shanghai Sangon Biotech Co., Ltd) and limestone (provided by the Institute of Geochemistry, Chinese Academy of Sciences).
