Xylulose and glucose fermentation by Saccharomyces cerevisiae in chemostat culture.
Saccharomyces cerevisiae ATCC 24860 was cultivated in chemostat culture under anoxic conditions with 111.1 mmol of glucose liter-1 alone or with a mixture of 66.7 mmol of xylulose liter-1 and 111.1 mmol of glucose liter-1. The substrate consumption rate was 5.4 mmol g of cells-1 h-1 for glucose, whereas for xylulose it was 1.0 mmol g of cells-1 h-1. The ethanol yield decreased from 0.52 carbon ...
متن کاملProlonged selection in aerobic, glucose-limited chemostat cultures of Saccharomyces cerevisiae causes a partial loss of glycolytic capacity.
Prolonged cultivation of Saccharomyces cerevisiae in aerobic, glucose-limited chemostat cultures (dilution rate, 0.10 h(-1)) resulted in a progressive decrease of the residual glucose concentration (from 20 to 8 mg l(-1) after 200 generations). This increase in the affinity for glucose was accompanied by a fivefold decrease of fermentative capacity, and changes in cellular morphology. These phe...
متن کاملComparative proteome analysis of Saccharomyces cerevisiae grown in chemostat cultures limited for glucose or ethanol.
The use of chemostat culturing enables investigation of steady-state physiological characteristics and adaptations to nutrient-limited growth, while all other relevant growth conditions are kept constant. We examined and compared the proteomic response of wild-type Saccharomyces cerevisiae CEN.PK113-7D to growth in aerobic chemostat cultures limited for carbon sources being either glucose or et...
متن کاملHybridization array technology coupled with chemostat culture: Tools to interrogate gene expression in Saccharomyces cerevisiae.
Hybridization array technology is increasingly being used for the analysis of gene expression in the yeast Saccharomyces cerevisiae. It is a powerful technique in which the relative abundance of all the mRNA molecules transcribed under a particular condition may be simultaneously measured. However, most studies performed using this technique are carried out in batch culture where the growth rat...
متن کاملResponse of Saccharomyces cerevisiae to REVIEW changes in external osmolarity
A few years ago, knowledge about the molecular and genetic details of osmoregulatory processes was confined to prokaryotes (reviewed by Csonka, 1989; Csonka & Hanson, 1991). Recently, however, numerous reports have been published describing genes, or their products, involved in the response of eukaryotic organisms to changes in the external osmolarity. Because of its genetic tractability, the b...
