It was discovered that the cell-free exudates of the methanogen Methanosarcina thermophila were capable of carbon tetrachloride (CT) and chloroform (CF) degradation. Characterization of the exudates suggested that the active agents were porphorinogen-type molecules, possibly containing zinc. This ...
(TGD) on Safety Assessment of Chemical Substances by the European Union was adopted to assess the ecological risks of nine chlorination by-products in the brine discharged from seawater utilization.The results showed that chloroform,chloral,dichloroacetate,trichloroacetonitrile and pentachlorophenol had ...
早期从环境中提取古DNA, 多针对研究对象的不同, 采用酚氯仿法(Phenol-chloroform method, PCI法)提取eDNA, 如Ochsenreiter等[46]利用eDNA研究高盐湖泊中古细菌多样性时, 在对样品进行过滤、经裂解液重悬和加入蛋白酶K后, 利用PCI法提取DNA。一直以来, 还是有很多eDNA的研究是采用PCI法提取DNA, 且也有研究表明...
Chlorine often imparts many desired properties in an organic compound when it is substituted for hydrogen (synthetic rubber), so it is widely use in organic chemistry, in the production of chlorates, chloroform, carbon tetrachloride, and in the bromine extraction. Chlorine in the environment In...
(THF) and chloroform(CHCl3).Meanwhile,flexible PI films were obtained,which had excellent thermal stability with the glass transition temperature(Tg) of 162.2~195.2℃ and the temperature at 10% weight loss of 444.2~467.5℃ in nitrogen atmosphere.The protonated polymer showed UV-Vis absorption in ...
In recent years, increasing interest on the effects of dietary components on epigenetic processes and, consequently, on the regulation of gene expression and metabolic responses has led clinical efforts worldwide to approach obesity. When inadequate, foo
Soybean roots (1.0 g) were baked at 105 °C for 5 min, then the samples were homogenized in a mixture of chloroform and methanol (1:2, V: V) and the homogenate was centrifuged at 1,000 × g for 10 min. The mixture of the supernatant and 0.76% NaCl was ...

such as chloroform and tetrachloroethylene (Di Lorenzo et al., 2015). Current guidelines suggest calculating R by adding up the risks associated with the individual contaminants in the mixture (EMA 2018a,b;Strona et al., 2019). However, synergistic effects should be considered, since they worsen...
