Microbially induced carbonate precipitation (MICP) is an important process in the synthesis of minerals, and thus, it widely explored as a novel approach with potential for many technological applications. However, processes mechanisms involved mineral formation presence microbes are not yet fully understood. This review covers current knowledge regarding role microbial cells metabolic products...

The strength and deformation properties of maritime geotechnical structures made primarily calcareous sand are critical for project safety. geogrid reinforcement is developed as a promising approach to improve the mechanical sand. This study investigates property biomodified via microbially induced calcite precipitation (MICP) process effectiveness A series unconsolidated undrained triaxial exp...

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 ...

Biomineralization technology offers an eco-friendly and efficient method for stabilizing heavy metals (HMs) in ecosystem. This comprises two primary methods: microbially induced carbonate precipitation (MICP) enzyme-induced (EICP). provides a superior alternative to stabilize due its low energy consumption, reduced carbon dioxide emissions, biocompatibility. In the process of biomineralization,...

Fibers are applied to construction works improve the strength and brittle failure of soil. In this paper, fibers with a length 6 mm added microbial cemented sand, fiber types content research variable. Unconfined compressive (UCS), permeability coefficient, water absorption rate, dry density, calcium carbonate precipitation solidified sand were tested. The physical mechanical properties on immo...

Many robotics problems, from robot motion planning to object manipulation, can be modeled as mixed-integer convex programs (MICPs). However, state-of-the-art algorithms are still unable solve MICPs for control problems quickly enough online use and existing heuristics typically only find suboptimal solutions that might degrade performance. In this work, we turn data-driven methods present the C...

Cracking is one of the main ways that concrete ages, allowing pollutants to seep within and potentially lowering physical mechanical strength endurance structures. One healing procedures merits research use bacterially generated calcium carbonate precipitation in mixtures mend cracks. The impact different variables, including nucleation location, bacterial type, concentration, uratolytic activi...

Microbial-induced calcium carbonate precipitation (MICP) has been successfully applied to self-healing concrete with improved mechanical properties, while the performance of engineered cementitious composites (ECC) incorporated bacteria is still lacking. In this study, Sporosarcina pasteurii, which a strong ability produce carbonate, was introduced into properties analyzed in detail. A multisca...
