Attachment on mortar surfaces by cyanobacterium Gloeocapsa PCC 73106 and sequestration of CO2 by microbially induced calcium carbonate Zhu, Tingting Merroun, Mohamed Larbi Cyanobacterium Gloe. PCC 73106 Extracellular polymeric substances Microbially induced carbonate precipitation Mortar durability Ontario Research Fund of Ministry of Research and Innovation, Grant/Award Number: 24591; National Science Engineering Research Council, Grant/Award Number: 354741; Canadian Foundation for Innovation, Grant/Award Number: 24591 Cyanobacterial carbonate precipitation induced by cells and extracellular polymeric substances (EPS) enhances mortar durability. The percentage of cell/EPS attachment regulates the effectiveness of the mortar restoration. This study investigates the cell coverage on mortar and microbially induced carbonate precipitation. Statistical analysis of results from scanning electron and fluorescence microscopy shows that the cell coverage was higher in the presence of UV-killed cells than living cells. Cells are preferably attached to cement paste than sand grains, with a difference of one order of magnitude. The energy-dispersive X-ray spectroscopy analyses and Raman mapping suggest cyanobacteria used atmospheric CO2 to precipitate carbonates. 2021-11-17T08:57:15Z 2021-11-17T08:57:15Z 2021-10-14 info:eu-repo/semantics/article Zhu, T...
