  • In this research, the growth and metabolic activities of Saccharomyces cerevisiae immobilized in alginate gel during alcoholic fermentation with different initial glucose concentration were studied. Starting from initial glucose concentration at 140 g/L, we observed that increasing this concentration to 220 g/L had little effect on the growth of immobilized yeast. Under the same conditions, the maximum biomass, glucose uptake rate, and final ethanol concentration obtained in the immobilized yeast cultures were always higher than those in the free yeast cultures....

  • In continuation of our reports on the chemical constituents of Croton tonkinensis Gagnep. (Euphorbiaceae) [1] this paper deals with the isolation and structure elucidation of two long chain alkyl alcohols. Two compounds 1 and 2 were isolated by repeated silica gel column chromatography of the n-hexane soluble fraction obtained from the methanol extract of the dried leaves of C. tonkinensis by liquid - liquid fractionation [2]. The long aliphatic chains of both compounds 1 and 2 were characterized by the 1 H and 13 C NMR spectra: H 0.88 (3H, t, J = 6.6 Hz), C 14.

  • A furanolabdane diterpene alcohol was isolated from the rhizomes of the endemic Vietnamese medicinal plant Alpinia tonkinensis Gagnep. (Zingiberaceae). Its absolute stereostructure was established to be (12S)-15,16-epoxy-8(17),13(16),14-labdatrien-12-ol from spectroscopic data and by applying the modified Mosher’s method. It is first report on the natural occurrence and absolute stereochemistry of the diterpene which was previously known as a synthetic intermediate.

  • Understanding the High-Functioning Alcoholic represents the untold story of millions of alcoholics.

The homeless person and the high-powered executive can both be alcoholics— alcoholism does not differentiate among socioeconomic class, education level, and appearance. However, because the high-functioning alcoholic (HFA) has the ability to perform and succeed, the treatment often comes too late or not at all.

  • MnOx/sepiolite catalysts were synthesized by precipitation method accompanied by the calcination at 4100C. The prepated solids have been characterized by XRD, SEM, TPR-H2. MnOx particles were deposited on the surface of the sepiolite fibers and act as active sites for the oxidation of benzyl alcohol using tert-butyl hydroperoxide (TBHP) as an oxidizing agent. The catalysts showed a good conversion of benzyl alcohol to benzaldehyde at 60 oC. The influence of the reaction time and reaction temperature was considered.
