I do not understand well to your question. Yeasts Saccharomyces cerevisiae are employed in full-scale operation nearly 100 years.

Best regards

You may make them alcohol tolerant by gradual selection of hyper ethanol producing strains. Such strains shall utilize most of sugar with least residual sugar content.

S. cerevisiae is preferred host for production of heterologous protein that required PTM for its biological activity. Yeast expression Attenborough is cost effective and amanable to scale up in boreactors

I think the answer is selectivity (natural and g-modified), cell wall composition, catabolic processes, extensive biosynthetic capasity, and stress tolerance.

Please make your question more clear. Good luck.

Yeast cells vary in size, shape and colour. Laboratory yeasts are usually smaller than industrial yeasts. Yeasts catabolize six-carbon molecules such as glucose into two carbon components, such as ethanol. Through bioengineering strains that possess improved substrate specificity, catalytic activity, ethanol tolerance catalysis of a wider range of substrates etc have been developed. You may need to read further on this based on your interests.

I agree with others that your question is unclear. Do you want to know what characteristics it already has or how to alter the strain characteristics. There is a large body of literature available for both of those questions. Please clarify.

Hi Yeye Lu, By the time it was established, there was no smart ways or techniques like today. It was all done by basic & traditional techniques and constant & combined effeorts of microbiologists, biochemists, chemical engineers, over a long period of time with trials and errors. Now, it may be the right time to do it more smartly and try it. Good luck. yr

Yeast i.e. Saccharomyces cerevisiae has been employed in full-scale operation for producing ethanol from starch and sugars for more than nearly 100 years and still no substtute for this. Depending on Sugar source and control of cross contamination, fermentation can be bone in batch, continous and fed batch mode at industrail scale.

Recent innovations in syn bio have allowed for the creation and use of yeast that endogenously produce various (costly) amalyses. This has lead to a reduction in the conversion cost of corn to fuel grade ethanol while also increasing yield and better managing osmotic stress (known as sugar shock in the industry).

Saccharomyces cerevisiae is very good yeast in fermentation process.

Following.

One may attempt to develop ethanol tolerant yeast strains soas to efficiently convert available carbohydrates to maximum ethanol.

Dear yeye,

S.cereviseae for large scale fermentation of what? There are wild types, adapted strains, genetically engineered ones etc., a better description would help us give you a better recommendation.
