Yeast growth is affected not only by the operative conditions (temperature, pH, sugar concentration) but also by the intrinsic properties of the investigated system, namely, type of strain, culture medium, and physiological state of the inoculum.

What grows yeast faster?

Yeast can use oxygen to release the energy from sugar (like you can) in the process called “respiration”. So, the more sugar there is, the more active the yeast will be and the faster its growth (up to a certain point – even yeast cannot grow in very strong sugar – such as honey).

What temperature will kill yeast?

120°FRegardless of the type of yeast you use, if your water reaches temperatures of 120°F or more, the yeast will begin to die off. Once water temps reach 140°F or higher, that is the point where the yeast will be completely killed off.
