To determine the correctness of the given statements, let's analyze each one:
Statement I: Whisky, brandy, and rum are produced without distillation of the fermented broth.
This statement is false. Whisky, brandy, and rum are actually produced through the distillation of the fermented broth. Distillation is a key process in concentrating the alcohol content and refining the flavors in these beverages.
Statement II: Saccharomyces cerevisiae is called doctor’s yeast.
This statement is true. Saccharomyces cerevisiae is commonly known as "baker's yeast," used in baking and brewing. The term "doctor's yeast" isn't widely recognized or used in academic literature, but historically, certain properties have been attributed to yeast strains that contribute to health benefits.
From the analysis, we determine: Statement I is false, but Statement II is true.
