متن کاملAnalysis of the Effects of Hyperosmotic Stress on the Derepression of Invertase Activities and the Growth of Different Baker's Yeast Strains
The growth of baker's yeast Saccharomyces cerevisiae in medium containing sucrose requires a high level of extracellular invertase enzyme activity. However, the expression of invertase is under the strict control of glucose repression in S. cerevisiae. In addition, invertase enzyme activity is also affected by physiological stress conditions that baker's yeast is exposed to during the various s...
متن کاملBaker’s yeast catalyzed Henry reaction: Biocatalytic C-C bond formation
The C-C bond formation is an important reaction in organic synthesis to obtain value-added intermediates. Therefore, in this paper an attempt has been made to accelerate the Henry reaction (C-C bond formation) between aryl aldehydes and nitromethane using less expensive whole cell biocatalyst, baker’s yeast (BY). The scope of the methodology was also tested for the heteryl aldehyde i.e. 2-chlor...

متن کاملPreparation of Highly Active Yeast Invertase*
In some preliminary experiments it was found that certain yeast invertase preparations which had been variously purified by adsorption to kaolin and alumina in accordance with the Willstiitter procedures (1) were soluble in saturated aqueous solutions of ammoniym sulfate. This solubility of the enzyme is interesting for two reasons. In the first place, saturated aqueous solution of ammonium sul...
