Effects of ammonium sulphate concentration on growth and glycerol production kinetics of two endogenic wine yeast strains
نویسنده
چکیده
Effects of initial ammonium sulphate concentration on growth and glycerol production kinetics of two endogenic wine yeast strains, Saccharomyces cerevisiae Kalecik 1 and Narince 3, were investigated in a batch system. Maximum specific growth rates for Kalecik 1 and Narince 3 were obtained at initial concentrations of 1.0 g/L, and 0.8 g/L ammonium sulphate, respectively. Further, maximum specific glycerol production rates and glycerol concentrations, for both of the strains, were obtained in the medium containing 0.3 g/L ammonium sulphate. In this medium, maximum glycerol concentrations were 6.4 g/L for the strain Kalecik 1, and 6.5 g/L for Narince 3.

Effects of pH and temperature on growth and glycerol production kinetics of two indigenous wine strains of Saccharomyces cerevisiae from Turkey
The study was performed in a batch system in order to determine the effects of pH and temperature on growth and glycerol production kinetics of two indigenous wine yeast strains Saccharomyces cerevisiae Kalecik 1 and Narince 3. The highest values of dry mass and specific growth rate were obtained at pH 4.00 for both of the strains. Maximum specific glycerol production rates were obtained at pH ...
متن کاملGlycerol overproduction by engineered saccharomyces cerevisiae wine yeast strains leads to substantial changes in By-product formation and to a stimulation of fermentation rate in stationary phase
Six commercial wine yeast strains and three nonindustrial strains (two laboratory strains and one haploid strain derived from a wine yeast strain) were engineered to produce large amounts of glycerol with a lower ethanol yield. Overexpression of the GPD1 gene, encoding a glycerol-3-phosphate dehydrogenase, resulted in a 1.5- to 2.5-fold increase in glycerol production and a slight decrease in e...

A new isolated strain of Sporobolomyces ruberrimus H110 was cultivated on technical glycerol as carbon source and effect of different temperatures and pH on the growth and pigmentation was studied. The maximum concentration of total carotenoid was 3.84 mgg-1 including torularhodin (3.70 mgg-1) and β-carotene (0.14 mgg-1) using 19ºC at pH 6, but the highest ...
متن کاملCombined effects of sulfites, temperature, and agitation time on production of glycerol in grape juice by Saccharomyces cerevisiae.
Analysis of variance was used to evaluate the simultaneous effects of strain, incubation temperature (15 to 25 degrees C), agitation time (0 to 24 h), and initial sulfite concentration (100 to 300 ppm) on glycerol production in grape juice by Saccharomyces cerevisiae. Fourteen strains were studied to determine their growth patterns in the presence of sulfites and ethanol. Baker's yeast strains ...
متن کاملEffects of GPD1 overexpression in Saccharomyces cerevisiae commercial wine yeast strains lacking ALD6 genes.
The utilization of Saccharomyces cerevisiae strains overproducing glycerol and with a reduced ethanol yield is a potentially valuable strategy for producing wine with decreased ethanol content. However, glycerol overproduction is accompanied by acetate accumulation. In this study, we evaluated the effects of the overexpression of GPD1, coding for glycerol-3-phosphate dehydrogenase, in three com...
