Hello Everyone,
I am trying to ferment the enzymatic hydrolysate I obtained after pretreatment to produce bioethanol. So, as a trial, I did the experiment in a fermenter using YPD and checked ethanol production using Saccharomyces strain purchased from a Supermarket locally. The yield I got was very low and the glucose consumption rate was also low. Can somebody please suggest where I can buy high-efficiency yeast strains from India that can be used for fermentation?. It would be a great help!.
Thanks in advance!

That was a good try but obviously the wrong place to purchase yeast for bioethanol production. Kindly note this most yeast on the shelf of a supermarket is meant for bread or food processes with low ethanol yield. Such yeast cannot be used for bioethanol production.
There are special yeast strains available for bioethanol which you can be sourced from Institutes in India such as universities known for such studies.
You can purchase yeast from Lallemand India. Please specify the ethanol yield you want. But also remember this, the amount of sugar present in your broth will determine the amount of ethanol yield.
Most importantly note this: the number of yeast cells required per Liter per amount of sugar present.
Kindly think through diligently before you proceed.
Hellie Gonu dear, its not only yeast that can effect the production of ethanol. temperature, media ingredients and concentration can also play a vital role in it. what temperature are you using in fermentation? by the way why dont you use SC90 which i used in my experiment ?
