The inhibition of urease from Sporosarcina pasteurii (SPU) and Canavalia ensiformis (jack bean, JBU) by a class six aromatic poly-hydroxylated molecules, namely mono- dimethyl-substituted catechols, was investigated on the basis inhibitory efficiency catechol scaffold. aim to probe key step mechanism proposed for SPU catechol, sulfanyl radical attack ring, as well obtain critical information ef...

Urease is an important enzyme both in agriculture and medicine research. Strategies based on urease inhibition is critically considered as the first line treatment of infections caused by urease producing bacteria. Since, urease possess agro-chemical and medicinal importance, thus, it is necessary to search for the novel compounds capable of inhibiting this enzyme. Several computational methods...

The governance of uranium tailings aims to improve stability and reduce radionuclide release. In order achieve this goal, the removal solution test grouting were successively carried out using microbially induced calcium carbonate precipitation (MICP) technology. effect MICP on reinforcement synchronous control in discussed. results show that Sporosarcina pasteurii could grow reproduce rapidly ...

Microbial-induced calcium carbonate precipitation (MICP) technology mainly uses carbonates produced by the reaction of microbial activities to repair rocks and soils. Temperature influences metabolism kinetics chemical reactions. In this study, experiments on fractured sandstone under different temperatures are carried out. The effects tested with nuclear magnetic resonance (NMR), an X-ray auto...

Recent research in the field of concrete materials showed that it might be possible to develop a smart cement-based material is capable remediating cracks by Microbial-induced calcium carbonate precipitation (MICP). The early remediation microcracks enables design systems with an elongated service life sustainable approach. However, main challenge application extend viability cells against rest...

The biochemical properties of CaCO3 precipitation induced by Sporosarcina pasteurii, an ureolytic type microorganism, were investigated. Effects of calcium source on the precipitation process were examined, since calcium source plays a key role in microbiologically induced mineralization. Regardless of the calcium source type, three distinct stages in the precipitation process were identified b...
