Question

Which of the following factor does not influence abnormal fermentation?

(a) Phenotype of yeast

(b) Viability of yeast

(c) Temperature

(d) Presence of inhibitors

I had been asked this question in an online interview.

Asked question is from Secondary Fermentation topic in section Fermentation System & Management of Fermentation Technology

Answer 1

Correct option is (a) Phenotype of yeast

To explain: Phenotype of yeast does not influence the abnormal fermentation. However, the genotype of yeast may lead to an abnormal fermentation. Presence of inhibitors, temperature, etc. are the factors that influence abnormal fermentation. The wort composition, yeast, microbiology, and the fermentation variables are the parameters that direct the abnormal fermentation.
