Question

Which of the following condition will enhance the growth of yeast?

a)Cold conditions (4 °C as in the refrigerator)

b)Warm conditions (25-30 °C)

c)Hot conditions (100 °C)


​

Answer 1

Answer:

b) Warm conditions (25-30°C)

Explanation:

Yeasts are active in a very broad temperature range - from 0 to 50° C, with an optimum temperature range of 20° to 30° C. ... Normal yeasts require a minimum water activity of 0.85 or a relative humidity of 88%. Yeasts are fairly tolerant of high concentrations of sugar and grow well in solutions containing 40% sugar.
