Terephthalic acid (PTA), a monomer in the synthesis of polyethylene terephthalate (PET), is obtained by the oxidation of petroleum-derived p-xylene. There is significant interest in the synthesis of renewable, biomass-derived PTA. Here, routes to PTA starting from oxidized products of 5-hydroxymethylfurfural (HMF) that can be produced from biomass are reported. These routes involve Diels-Alder ...
the aim of this study was to investigate the effect of bacterial inoculation on the fermentation and aerobic stability of corn silage and on the dry matter degradability and milk composition when fed to sheep or cows. four male sheep were selected to measure dry matter degradability of uninoculated (ucs) and inoculated (ics) corn silage. milk composition was measured for 22 holstein cows, separ...
Abstract Background and objectives: Tuberculin is the proteins existed in tuberculosis culture medium which precipitated by trichloroacetic acid (TCA) or ammonium sulfate. Tuberculin is used for diagnosis of Tuberculosis. The aim of this study is to compare the human tuberculin produced by Razi Institute and Mycobacterium tuberculosis Culture Filtrate Protein. Material and Methods: Initially By...
An efficient simplified isotope dilution method was developed to determine four carboxyl containing phytohormones simultaneously in 200 mg of fresh tomato tissues using ultra high performance liquid chromatography-triple quadrupole mass spectrometry (UPLC-MS/MS) with negative electrospray ionization. The four phytohormones are indole-3-acetic acid (IAA), abscisic acid (ABA), jasmonic acid (JA),...
