Bioconversion of amino acids into flavouring alcohols and esters by Erwinia carotovora subsp. atroseptica
1991
International audience; Erwinia carotovora subsp. atroseptica produced flavour compounds when infecting endives (Cichorium intybus). These compounds were identified as esters and branched-chain alcohols.They were produced from amino acids and some of them such as methionol, methionol acetate, isobutanol, isobutyl acetate, beta-phenyl ethanol and tryptophol were produced with good yields.
Vapor−Liquid Equilibria for the Binary Systems Isobutanol with m-Xylene, o-Xylene and p-Xylene at 101.3 kPa
1999
Vapor−liquid equilibria were measured for binary systems of isobutanol with m-xylene, o-xylene, and p-xylene at 101.3 kPa using a recirculating still. The accuracy of experimental measurements was ±0.1 K in temperature, ±0.01 kPa in pressure, and ±0.001 in mole fraction. The results were determined to be thermodynamically consistent according to the point-to-point consistency and Wisniak tests. All the systems show moderate positive deviations from ideality. The data were correlated with five liquid-phase activity coefficient models (Margules, Van Laar, Wilson, NRTL, UNIQUAC).
Die Bildung höherer Alkohole bei Aminosäuremangelmutanten von Saccharomyces cerevisiae III. Höhere Alkohole als Nebenprodukte der Aminosäuresynthese
1975
Summary The formation of higher alcohols as byproducts of the synthesis of threonine, isoleucine and valine was investigated using isogenic haploid and diploid mutant strains of Saccharomyces cerevisiae . Genetic markers were ade 2, leu 1. The growth rate, the formation of ethanol, the amino acid metabolism and the formation of higher alcohols were determined during fermentations in a synthetic medium. n-Propanol-1, 2-methylbutanol-l and isobutanol were synthesized parallel to ethanol formation during exponential and stationary growth phase. However, the formation of 3-methylbutanol-l from leucine was restricted to the exponential phase. A comparison of haploid and diploid strains revealed,…
