1. Factors affecting fermentation of yeast aside from pH are listed below :
a. Temperature
b. oxygen
c. Water
How can they accomplish this?
1. Temperature
To decide the optimum temperature for fermentation of yeast temperature experiments carried out.
Generally 20-30 degrees centigrade is the optimum temperature for fermentation of yeast.
2. Oxygen
presence of excess oxygen during the yeast fermentation leads to the production of acetic acid which is undesirable. So they maintain sufficient oxygen neither less nor more.
3. Water
The water requirement of yeast is less than bacteria and more than moulds. Approximate water activity requirement is 0.85.
