Biomineralization is a common phenomenon in nature, and the use of microbial-induced calcium carbonate precipitation (MICP) technology for engineering construction successful attempt to utilize natural biological phenomena, which has become hot topic current research. There are many factors affecting MICP, such as bacterial properties external environmental factors. Many scholars have carried out lot research on these factors, but even under appropriate conditions, MICP process still problem low efficiency. According different engineering, tolerance effect bacteria environments also different. At same time, cultivation preservation will consume large amount raw materials, far more significant than cost construction. The efficiency limit large-scale application this practical engineering. In response problems, researchers exploring new ways improve technology. Based used paper explores mechanism reviews improvement from perspective economy.

Abstract Electrochemical-phytoextraction is considered as an integrated technology for removal of Cd in contaminated soil. However, there a lack systematic studies on the how electric field frequency plant enrichment and soil microbial properties, which has restricted optimised application technology. This study investigated influence alternating current (AC) at frequencies 50 Hz 300 accumulation willow (Salix spp.), availability, properties. Exposure to AC resulted different degrees increase biomass production leaves, branches, stems, roots; concentrations N, P, K willow; increased root volume surface area; promoted photosynthesis willow. Compared with control, significantly enhanced above-ground parts roots by 14.65% 9.48%, respectively. Moreover, exposure availability 8.34% 19.26% Hz, decreased urease activity but peroxidase acid, phosphatase, activity. suggests that modulate interactions between Cd, enzymes, microbes. Although generally inhibit enzyme activity, can alter environment, reduce toxic effects, enhance oxidative stress responses nutrient cycling, mitigate toxicity. Therefore, these results indicate growth, altered ultimately leading uptake In particular, exhibited greater impacts enrichment.
