In the framework of development green analytical chemistry, a silica gel (SG) coated with semi-penetrating network based on partially biosourced poly(ethersulfone) is studied for greener extraction process aromatic organic pollutants. An optimized composition (80% linear polymer (LP): isosorbide-based and 20% cross-linking agent (XP) type bismaleimide) leads to total adsorption selected polluta...

m-toluic acid (MTA) is widely used in manufacturing of dyes, pharmaceuticals, polymer stabilizers, and insect repellents. The aim of present study was to evaluate the impact of biofield treatment on physical, thermal and spectroscopic properties of MTA. MTA sample was divided into two groups that served as treated and control. The treated group received Mr. Trivedi’s biofield treatment. Subsequ...

Abstract Background Biochar ozonization was previously shown to dramatically increase its cation exchange capacity, thus improving nutrient retention capacity. The potential soil application of ozonized biochar warrants the need for a toxicity study that investigates effects on microorganisms. Results In presented here, we found filtrates collected from pine 400 and rogue did not have any inhib...

Terephthalic acid (TPA) is an important industrial chemical currently produced by energy intensive and potentially hazardous p-xylene (pX) oxidation process. Here we report the development of metabolically engineered Escherichia coli system for biological transformation of pX into TPA. The engineered E. coli strain harbours a synthetic TPA pathway optimized through manipulation of expression le...

The metabolism of o-cresol under methanogenic conditions by an anaerobic consortium known to carboxylate phenol to benzoate was investigated. After incubation with the consortium at 29 degrees C for 59 days, o-cresol was transformed to 3-methylbenzoic acid, which was not further metabolized by the consortium. Proteose peptone in the culture medium was essential for the transformation of o-creso...
