Characterization of an Interesting Novel Mutant Strain of Commercial Saccharomyces cerevisiae

The yeast strains that are resistant to high concentration of ethanol have biotechnological benefits and aresuitable models for physiology and molecular genetics research fields. A novel ethanol-tolerant mutant strain,mut1, derived from the commercial Saccharomyces cerevisiae showed higher ethanol production, and alsodemonstrated resistance to ethanol but not to other alcohols...

Saccharomyces cerevisiae TFS9, a novel isolated yeast capable of high caffeine-tolerant and its application in biodecaffeination approach

There is a great call for using microbial bio-decaffeination approach to remove caffeinefrom caffeinated products and industrial wastes. We aimed in this study to screen strainsof yeasts which exhibit high caffeine tolerance and to investigate the bio-degradation ofcaffeine under growth conditions. Sixteen yeast strains were isolated from the cultivatedtea soils collected from sites of northern...

Study of Organic Solvent Tolerance and Increased Antibiotic Resistance Properties in E. coli gyrA Mutants

   Ciprofloxacin is one of the most widely used antibiotics for the treatment of several infections caused by Gram-negative bacteria, like E. coli. Changes in gyrA, encoding GyrA subunit of DNA gyrase, cause the resistance to ciprofloxacin. Some ciprofloxacin resistant gyrA mutants acquired constitutive expression of marRAB operon due to the gaining mutations in marR, a repressor of this operon...
