https://www.selleckchem.com/products/biib129.html In vitro studies using 90-days gut microbial culturing experiments indicated that gut microbiota contributed to PS degradation. Our research demonstrates that intestinal bacteria played an essential role in the degradation of PS by Z. morio, and provides a new theoretical basis and application ideas for the biodegradation of PS.Red soil from Guangxi, China was selected as the background soil, and a porous biomorphic genetic composite of α-Fe2O3/Fe3O4/C comprising a bamboo template (PBGC-Fe/C) was used as a passivator to remediate As(Ⅴ) contaminated soils. The performance of PBGC-Fe/C was characterized by Scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FT-IR). The results showed that PBGC-Fe/C could improve the passivation effect of As(Ⅴ) from the contaminated soils compared with a single passivation material. Under the conditions of a 5% dose addition, 25% water content, and particle size of 100 mesh, the stability rates of PBGC-Fe/C on As(Ⅴ) contaminated soils with different concentrations of 500 mg·kg-1 and 1000 mg·kg-1 could reach 80.95% and 73.49%, respectively. The porous biomorphic genetic composite of bamboo charcoal provided a large number of adsorption sites for As(Ⅴ), and the acidity of the soil was favorable for the remediation of As(Ⅴ) via passivation. Moreover, PBGC-Fe/C could not only adsorb and fix As(Ⅴ), but also promoted the stabilization of As species. Chemical complexation and ion exchange played major roles in this passivation process.To reveal the effects of diethyl aminoethyl hexanoate (DA-6) combined with L-Glutamic acid, N,N-diacetic acid (GLDA) on the remediation of Cd contaminated soils by Panicum virgatum L., different GLDA application methods with total application doses of 600, 1200, and 2400 kg·hm-2equally divided 1, 2, and 4 times, respectively, were studied on the basis of DA-6 concentrations of 0 and 10 μmol·L-1, and applicatio
