[Thermotolerant variants of wine yeasts].
Mikrobiologiia, 1980Under the action of elevated temperature (37 degrees C), wine yeasts sported thermotolerant variants with respiration deficiency and increased fermentative function. The activity of dehydrogenase in the variants was also low. The sediment of Saccharomyces vini cells became dust-like instead of flocculent at 37 degrees C.

Biomass production by a thermotolerant yeast: Hansenula polymorpha
Journal of Chemical Technology & Biotechnology, 1990AbstractBiomass production at high temperature by Hansenula polymorpha as part of a lignocellulosic utilizing process was studied. Compromise growth conditions (45°C and pH = 4.8) with an eventual saccharification step were established. The effects of stirring rate and initial glucose concentration on biomass yield coefficient, volumetric productivity ...

Rapid growth of a thermotolerant yeast on palm oil
World Journal of Microbiology and Biotechnology, 1993A thermotolerant and rapidly-growing yeast for production of single cell protein from palm oil was isolated and identified as Candida tropicalis F129. The optimum temperature and pH for growth were 38°C and 6.0, respectively. The yeast grew with a high specific growth rate, of 0.92/h in 2% (v/v) palm oil medium, compared with other oil-assimilating ...

Kluyveromyces fragilis SS-437: An associatively-profiled thermotolerant yeast
Antonie van Leeuwenhoek, 1987The lactose-utilizing Kluyveromyces fragilis SS-437 was found to have an associative temperature profile, but a thermotolerant growth yield behaviour. Cardinal growth temperatures were: 3 degrees C minimum for growth; 41.5 degrees C optimum; 44.5 degrees C final maximum (growth and death rates equalize); 46.1 degrees C initial maximum (maximum limit ...

Sodium Azide Reduces the Thermotolerance of Respiratively Grown Yeasts
Current Microbiology, 2002The effect of sodium azide in heat shock-induced cell death was studied in Debaryomyces vanrijiae, Candida albicans, and Saccharomyces cerevisiae yeasts. The results presented demonstrate that the azide addition induced a drastic decrease in the thermotolerance of glucose-grown D. vanrijiae. In contrast, glucose-grown S. cerevisiae and C.

Thermotolerance and barotolerance of alcohol-shocked yeast
2002The acquisition of stress tolerance in response to a preconditioning alcohol shock treatment at various concentrations was studied using eight kinds of alcohols in the yeast Saccharomyces cerevisiae. Alcohol shock treatment induced tolerance against stresses such as high temperature and high pressure in yeast.

Biofuels. Altered sterol composition renders yeast thermotolerant.
Science (New York, N.Y.), 2014Ethanol production for use as a biofuel is mainly achieved through simultaneous saccharification and fermentation by yeast. Operating at ≥40°C would be beneficial in terms of increasing efficiency of the process and reducing costs, but yeast does not grow efficiently at those temperatures.

Ethanol and thermotolerance in the bioconversion of xylose by yeasts
2000The mechanisms underlying ethanol and heat tolerance are complex. Many different genes are involved, and the exact basis is not fully understood. The integrity of cytoplasmic and mitochondrial membranes is critical to maintain proton gradients for metabolic energy and nutrient uptake. Heat and ethanol stress adversely affect membrane integrity.
