Synthesis and Utilisation of Hybrid Metal-Carbonic Anhydrase Enzyme Carrier System for Soil Biocementation
نویسندگان
چکیده
Biocementation is an emerging nature-inspired method of producing eco-friendly cement for soil stabilization. This paper used the bovine-derived carbonic anhydrase (CA) enzyme to catalyse bioprecipitation CaCO3 in a fine-grained and thus biocement soil. To increase efficiency CA, innovative copper–carbonic hybrid was fabricated. study proof-of-concept potential application these carriers biocementation. The are aimed enhance stability, recovery reusability biocementation process. results showed that fabricated copper phosphate-based inorganic stable throughout duration tests (2 months) under wide range pH temperatures. Its enzymatic activity enhanced compared free CA it proved suitable further confirmed by SEM analysis. Additionally, treated with formulated carrier improved unconfined compressive strength, especially when were implemented into mixing. material analysis Raman spectroscopy calcium carbonate as primary precipitate, consistent Overall, this delivery enzymes stability shows promise that, upon development, can be successfully sustainability

UNDER the name of carbonic anhydrase Meldrum & Roughton [1933] 2 described a new enzyme present in red blood corpuscles which catalyses both phases of the reversible reaction: H2CO3, CO2+ H20. They purified this enzyme from mammalian erythrocytes and gave a detailed account of its properties and the kinetics of the reactions which it catalyses. The greatly purified enzyme preparation obtained b...

Carbonic anhydrase was the earliest known zinc metallo-enzyme (4). It has been isolated from various sources, mainly mammalian red blood cells (see (5)). Although several methods for the preparation of highly active enzyme were described earlier, adequate purification was not achieved nor was the stoichiometry of zinc established (5). Recently, bovine erythrocyte carbonic anhydrase, homogeneous...
