Question

Identify the microorganism that is industrially used for baker's yeast production?

• A. Aspergillus niger
• B. Saccharomyces cerevisiae
• C. Penicillium chrysogenum
• D. Lactobacillus

Hint:

Remember the common industrial microorganisms: \[ \boxed{ \begin{aligned} \textit{Saccharomyces cerevisiae} &\rightarrow \text{Baker's yeast} \textit{Aspergillus niger} &\rightarrow \text{Citric acid} \textit{Penicillium chrysogenum} &\rightarrow \text{Penicillin} \end{aligned} } \]

Answer 1

The Correct Option is B

Step 1: Recall the industrial uses of microorganisms. \[ \begin{aligned} \textit{Saccharomyces cerevisiae} &\rightarrow \text{Bread and alcohol production}, \textit{Aspergillus niger} &\rightarrow \text{Citric acid production}, \textit{Penicillium chrysogenum} &\rightarrow \text{Penicillin production}, \textit{Lactobacillus} &\rightarrow \text{Curd and lactic acid production}. \end{aligned} \]

Step 2: Identify the baker's yeast. The organism used commercially as baker's yeast is \[ \boxed{\textit{Saccharomyces cerevisiae}.} \] Therefore, \[ \boxed{(B)} \] is the correct answer.
