- P-1, Q-3, R-2, S-4
- P-3, Q-4, R-1, S-2
- P-3, Q-4, R-2, S-1
- P-1, Q-4, R-3, S-2
Correct Option: B
P>3 : Saccharomyces cerevisiae is used extensively in batch fermentations to convert sugars to ethanol for the production of beverages and biofuels.
Q>4 : Probiotics are live microorganisms thought to be beneficial to the host organism. Lactic acid bacteria (LAB) and bifidobacteria are the most common types of microbes used as probiotics.
R>1 : In production technique of citric acid, cultures of A. niger are fed on a sucrose or glucose containing medium to produce citric acid.
S>2 : Sauerkraut (sour cabbage) is finely shredded cabbage that has been fermented by various lactic acid bacteria, including Leuconostoc, Lactobacillus, Pediococcus etc.
