The answer is generally yes, but it depends on the type of supplement. If the label indicates that the tablet is designed to be crushed, then it should be safe to do so. However, some supplements are designed to release the calcium slowly, and crushing them may affect their absorption. Additionally, some calcium supplements may have a coating ...

sent the thermodynamically favoured, enduring configurations of calcium carbonate), depending on the specific conditions of the reaction (e.g., rhomboidal or amorphous cal-cite, vaterite, etc.). The specific form of calcium carbonate produced through MICP can impact the physical properties of the solidified material. For instance, …
Batch fermentation of 60g/l glucose/xylose mixture by Clostridium acetobutylicum ATCC 824 was investigated on complex culture medium. Different proportions of mixtures, ranged between 10 and 50g of each sugar/l, were fermented during pH control at 4.8 (optimum pH for solventogenesis) or during CaCO3 addition. Using xylose-pregrown cells and pH …
Microbial precipitation of calcium carbonate takes place in nature by different mechanisms. One of them is microbially induced carbonate precipitation (MICP), which is performed due to bacterial hydrolysis of urea in soil in the presence of calcium ions. The MICP process can be adopted to reduce the permeability and/or increase the shear …
In this work, we discovered that the calcium-dependent 3D organization of the biofilm colony leads to transcriptional reprogramming of the bacterial community and was essential for biofilm development. Calcium carbonate was produced by two unrelated lung pathogens – P. aeruginosa and M. abscessus.
However, the precise control of microbial-induced calcium carbonate precipitation remains a formidable challenge in engineering practices, owing to the uncertain movement paths of bacteria and the ...
Isolation of mineral-forming strains on calcium carbonate and struvite media revealed six major colonies with a carbonate or struvite precipitation capacity in the biofouling on the membrane surface and showed that heterotrophic bacteria with the ability to precipitate calcium carbonate and struvite constituted ~7.5% of the total platable bacteria.
