Isolation of Thermotolerant Yeast Strains for Ethanol Production: A Need for New Approaches

نویسنده

چکیده

There is a need for new approaches to isolate thermotolerant yeast strains that can be utilized for the efficient production of ethanol. The simultaneous saccharification and fermentation of starch or lignocellulosic will greatly benefit from thermotolerant yeast strains that actively ferment ethanol at temperatures above 40°C. The development of new procedures targeting the cell membrane to increase thermotolerance in yeast strains represents an opportunity to advance the ethanol industry.

A novel high ethanol-thermo-tolerant Acetobacter pasteurianus KBMNS-IAUF-2 strain and the optimization of acetic acid production using the Taguchi statistical method

Because of the high energy consumption for fermentor cooling, the isolation of thermo-tolerant Acetobacter strains for vinegar production has a high priority. The aims of this study were the isolation and identification of a high ethanol-thermo-tolerant Acetobacter spp. from grapes as well as the optimization of conditions for increasing the acetic acid production. The grape e...

Thermotolerant Yeast Strains Adapted by Laboratory Evolution Show Trade-Off at Ancestral Temperatures and Preadaptation to Other Stresses

UNLABELLED A major challenge for the production of ethanol from biomass-derived feedstocks is to develop yeasts that can sustain growth under the variety of inhibitory conditions present in the production process, e.g., high osmolality, high ethanol titers, and/or elevated temperatures (≥ 40 °C). Using adaptive laboratory evolution, we previously isolated seven Saccharomyces cerevisiae strains ...

Heat-shock and ethanol-osmotic effect on fermentable yeast cells

This study investigated the effect of heat and ethanol on fermentable yeast cells. Fermentable yeast cells (Saccharomyces cerevisiae strains and non-saccharomyces species) were subjected to varying temperature (37, 40 and 44°C) and ethanol concentration (8, 10, 14 and 18%) respectively. In the research, 55.35% of the fermentable yeasts were highly thermotolerant, moderately thermotolerant (42.8...
