TI  - Formate oxidation-driven calcium carbonate precipitation by Methylocystis parvus 
      OBBP.

AB  - Microbially induced carbonate precipitation (MICP) applied in the construction 
      industry poses several disadvantages such asammonia release to the air and nitric 
      acid production. An alternative MICP from calcium formate by Methylocystis parvus 
      OBBP is presented here to overcome these disadvantages. To induce calcium 
      carbonate precipitation, M. parvus was incubated at different calcium formate 
      concentrations and starting culture densities. Up to 91.4% +/- 1.6% of the initial 
      calcium was precipitated in the methane-amended cultures compared to 35.1% +/- 
      11.9% when methane was not added. Because the bacteria could only utilize methane 
      for growth, higher culture densities and subsequently calcium removals were 
      exhibited in the cultures when methane was added. A higher calcium carbonate 
      precipitate yield was obtained when higher culture densities were used but not 
      necessarily when more calcium formate was added. This was mainly due to salt 
      inhibition of the bacterial activity at a high calcium formate concentration. A 
      maximum 0.67 +/- 0.03 g of CaCO3 g of Ca(CHOOH)2(-1) calcium carbonate precipitate 
      yield was obtained when a culture of 10(9) cells ml(-1) and 5 g of calcium 
      formate liter(-)1 were used. Compared to the current strategy employing biogenic 
      urea degradation as the basis for MICP, our approach presents significant 
      improvements in the environmental sustainability of the application in the 
      construction industry.
