	List I		List 2
A	Sacharomyces cerevisiae	1	Production of immunosuppressive agents
B	Monascus purpureus	2	Ripening of Swiss cheese
C	Trichoderma	3	Commercial production of ethanol
D	Propionibacterium sharmanii	4	Production of blood cholesterol lowering agents

• A. A - iii, B - i, C - iv, D - ii
• B. A - iii, B - iv, C - i, D - ii
• C. A - iv, B - iii, C - ii, D - i
• D. A - iv, B - ii, C - i, D - iii

Answer 1

The correct option is B A - iii, B - iv, C - i, D - ii

The source of ethanol for industrial use was from the fermentation of sugars by yeast (Sacharomyces cerevisiae). Red yeast rice is a substance that's extracted from rice that's been fermented with a type of yeast called Monascus purpureus. Red yeast rice is a traditional Chinese medicine that has been used to lower cholesterol. Trichoderma is used as an immunosuppressant prescribed in organ transplants to prevent rejection. There are three primary types of bacteria that are used to make Swiss cheese: Streptococcus thermophilus; Lactobacillus helveticus; and Propionibacterium shermanii. It is this Propionibacterium shermanii that is responsible for the holes in Swiss cheese.

So, the correct answer is option B.
