Microbially induced calcium carbonate precipitation (MICCP) is a naturally occurring
biological process in which microbes produce inorganic materials as part of their basic …

Concrete is one of the most widely used construction materials and has a high tendency to
form cracks. These cracks lead to significant reduction in concrete service life and high …

Microbes play key geoactive roles in the biosphere, particularly in the areas of element
biotransformations and biogeochemical cycling, metal and mineral transformations …

Micro-organisms contribute to Earth's mineral deposits through a process known as bacteria-
induced mineral precipitation (BIMP). It is a complex phenomenon that can occur as a result …

Gram-negative cell walls are strong enough to withstand 3 atm of turgor pressure (40), tough
enough to endure extreme temperatures and pHs (eg, Thiobacillus ferrooxidans grows at a …

There are various mechanisms through which bacteria precipitate calcium carbonate, out of
which a few have been recognised for application in concrete for crack healing. This paper …

Biomineralization refers to the processes by which organisms form minerals. The control
exerted by many organisms over mineral formation distinguishes these processes from …

Microorganisms modify rates and mechanisms of chemical and physical weathering and
clay growth, thus playing fundamental roles in soil and sediment formation. Because …

The goal of this study is to explore a new self-healing concept in which fungi are used as a
self-healing agent to promote calcium mineral precipitation to fill the cracks in concrete. An …

Nanoparticles are discrete nanometer (10-9 m)-scale assemblies of atoms. Thus, they have
dimensions between those characteristic of ions (10-10 m) and those of macroscopic …
