The use of bacteria for self-healing cement-based materials has shown great potential in recent years. Microbially induced calcium carbonate precipitation (MICP) is a novel technology that relies on the metabolic activity bacteria, principally from genus Bacillus and close relatives, to precipitate (CaCO3) inside cracks heal them. Among different can be used this purpose, aerobic non-ureolytic ...

Microbially induced calcium carbonate precipitation (MICCP) is a naturally occurring biological process in which microbes produce inorganic materials as part of their basic metabolic activities. This technology has been widely explored and promising with potential in various technical applications. In the present review, the detailed mechanism of production of calcium carbonate biominerals by u...

Urease is a virulence factor found in various pathogenic bacteria. It is essential in colonization of a host organism and in maintenance of bacterial cells in tissues. Due to its enzymatic activity, urease has a toxic effect on human cells. The presence of ureolytic activity is an important marker of a number of bacterial infections. Urease is also an immunogenic protein and is recognized by an...

The ureolytic bacteria and nutrients were immobilized in the artificial functional carrier (AFC) self-healing cement mortar, based on AFC-encapsulated bacteria, was prepared for this paper. crack effect of mortars with without under different exposure environments (standard curing, dry–wet cycle water curing) investigated by visual observation surface internal cracks, permeability tests, mechan...
