متن کاملSelf-healing of Early Cracks in Cement-based Materials by Carbonic Anhydrase Microbiologically Precipitation Calcium Carbonate
ID No: 65 ABSTRACT This research studies the self-healing potential of early cracks in cement-based materials incorporating carbonic anhydrase (CA) bacteria. CA bacteria can accelerate the CO2 hydrated reaction then transfer CO2 to HCO3 which can react with soluble Ca(OH)2 on the surface of specimens. Calcium carbonate deposits because of the reaction of HCO3 with Ca.This research studies the s...
متن کاملCalcium, carbonic anhydrase and gastric acid secretion.
Previous data concerning the action of calcium (Ca) on gastric acid secretion (GAS) indicated that calcium ions increase GAS elicited by gastrin released through a vagal mechanism, and also by a direct effect on parietal cells. Our research showed that the stimulating effect of calcium on gastric acid secretion can be antagonized by verapamil administration, which reduces gastric acid secretion...
متن کاملIntracellular location of carbonate dehydratase (carbonic anhydrase) in leaf tissue.
Two proteins which have carbonate dehydratase (carbonic anhydrase, EC 4.2.1.1) activity were shown to be in the chloroplasts and in the cytosol of leaves of Brassica chinensis, Spinacia oleracea, and in variegated leaves of Tradescantia albiflora and Hedera canariensis. The chloroplastic enzyme is smaller than the one in the cytosol, as it runs farther on gradient polyacrylamide gels. It was se...
متن کاملStrain-specific ureolytic microbial calcium carbonate precipitation.
During a study of ureolytic microbial calcium carbonate (CaCO(3)) precipitation by bacterial isolates collected from different environmental samples, morphological differences were observed in the large CaCO(3) crystal aggregates precipitated within bacterial colonies grown on agar. Based on these differences, 12 isolates were selected for further study. We hypothesized that the striking differ...
