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...

The present work explores the adaptive behavior of well-known ureolytic bacterial strain namely Sporosarcina pasteurii for microbial-induced calcite precipitation (MICP) under saline environment. MICP activity was observed up to 10% NaCl supplementation and confirmed by several characterization techniques viz. scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analys...

Biomineralisation offers the potential for in-situ sequestration and subsequent reduction in the bioavailability of heavy metals and radionuclides in the subsurface environment. Calcium carbonate minerals are known to sorb and form solid solutions with a range of target elements, and are readily produced by the actions of common microorganisms on simple chemical precursors. The ability of a com...

Recently, the bio-mediated soil improvement techniques have gained an increasing attention. In this method, bacteria was cultivated aerobically in laboratory and added to with reactant solutions such as urea calcium chloride. Most of existing studies are on sandy soils a few researches done silty soils. However, most nature compounds fine-grained coarse-grained soils, silt does not very good re...

Abstarct Despite a broad application of ureolytic bacteria in many bioremediation and biocementation processes, very limited studies have reported their transport retention behaviors under various physical–chemical–biological conditions. In this study, we report Sporosarcina pasteurii saturated sand, based on series column breakthrough experiments different conditions including ionic strengths ...

This research focused on the evaluation of potential use a soil-isolated bacteria, identified as Staphylococcus equorum, for microbial-induced calcite precipitation (MICP) and copper removal. Isolated bacteria were characterized considering growth rate, urease activity, calcium carbonate precipitation, tolerance minimum inhibitory concentration (MIC) precipitation. Results compared with Sporosa...
