Solution

i-e, ii-a, iii-d, iv-c, v-b
Statins- Monascus purpureus
$$\bullet$$ Monacolin k is the principal statin produced by M. Purpureus
Cyclosporin A$$\rightarrow$$ Trichoderma polysporum
$$\bullet$$ It is produced by submerged fermentation of aerobic fungi
$$\bullet$$ Swiss cheese $$\rightarrow$$ Propionibacterium sharmani
$$\bullet$$ Citric acid $$\rightarrow$$ Aspergillus niger
$$\bullet$$ Produced by submerged fermentation
$$\bullet$$ Clot bluster$$\rightarrow$$ Streptokinase is the enzyme mainly responsible for it which is produced by streptokinase producing Streptococcus bacteria.
Question 2
1 / -0

During biogas production acetic acid is transformed into the final product by the enzymes of ________

A
Clostridium

B
Pseudomonas

C
Penicillium

D
Methanobacillus

Solution

Question 3

1 / -0

Match and find the correct combination.

(a)	Fermenting malted cereals and fruit juice	(i)	Clots in Blood vessels
(b)	Production of large holes in Swiss cheese	(ii)	Digestion of sludge by bacteria and fungi resulting in emission methane and other gases
(c)	Myocardial infarction	(iii)	Production of ethanol
(d)	Biogas	(iv)	Blood cholesterol lowering agent
		(v)	Production of large amount of CO$$_2$$

a-iii, b-v, c-iv, d-ii

a-i, b-ii, c-iii, d-iv

a-iii, b-v, c-i, d-ii

a-v, b-iv, c-iii, d-ii

Question 4

1 / -0

Match and find the correct combination.

(a)	Statin	(i)	Remove the clots in blood vessels
(b)	Cyclosporin A	(ii)	Competitive inhibitor of cholesterol synthesizing enzyme
(c)	Streptokinase	(iii)	Immunosuppressant
(d)	Lipase	(iv)	Soap industry to remove oil stains

a-ii, b-iii, c-i, d-iv

a-iv, b-ii, c-iii, d-i

a-iii, b-ii, c-iv, d-i

a-iv, b-i, c-iii, d-ii

Solution

Question 5
1 / -0

Identify the microorganism that produces biomass of proteins.

A
Monascus purpureus

B
Aspergillus niger

C
Methylophilus methylotropus

D
Trichloderma polysporum
Question 6
1 / -0

Supply of oxygen to biogas plant causes

A
Positive effect

B
Negative effect

C
No effect

D
None of the above

Solution

Biogas is mixture of gases produced by the breakdown of organic matter in the absence of oxygen. Biogas plant works under anaerobic condition. In this, manure is anaerobically digested and the biogas is produced. The biogas contains methane and carbon dioxide. Supply of oxygen to biogas plant causes negative effect.
Thus, the correct answer is 'Negative effect.'
Question 7
1 / -0

Sewage water is purified by

A
Microorganisms

B
Light

C
Fishes

D
Aquatic plants

Solution

Sewage is composed of organic matter and domestic waste. The pollutants are removed by the sewage treatment process to mitigate it's adverse impact on the environment when it is released. The sewage pass through primary, secondary and tertiary treatment. The microorganisms by aerobic and anaerobic metabolism degrade the organic matter in secondary and tertiary treatment respectively making it disinfected.
Hence, the correct answer is 'Microorganisms'.
Question 8
1 / -0

Which is wrongly matched?

A
Clostridium butylicum - Lipase - Removal of oil stains

B
Trichoderma polysporum - Cyclosporin A- Immunosuppressive drug

C
Monascus purpureus - Statins - Lowering of blood cholesterol

D
Streptococcus - Streptokinase - Removal of clot from blood vessel
Question 9
1 / -0

Immunosuppressive cyclosporin A is obtained from

A
Aspergillus niger

B
Penicillium notatum

C
Monascus purpureus

D
Trichoderma poplysporum

Solution

Cyclosporin is an effective immunosuppressant used in the treatment of autoimmune disorders (such as rheumatoid arthritis) and in organ transplantation to prevent rejection. Cyclosporin lowers the activity of T-cells and hence, suppressing the activity of the immune system. Cyclosporin is isolated from the fungus Trichoderma polysporum. Common side effects include high blood pressure, headache, kidney problems, increased hair growth, and vomiting.
So, the correct answer is 'Trichoderma polysporum'.
Question 10
1 / -0

Match the columns and find the correct option.
I II
(a) Citric acid (i) Trichoderma
(b) Cyclosporin (ii) Clostridium
(c) Statins (iii) Aspergillus
(d) Butyric acid (iv) Monascus

A
a-iii, b-iv, c-i, d-ii

B
a-iii, b-i, c-ii, d-iv

C
a-iii, b-i, c-iv, d-ii

D
a-i, b-iv, c-ii, d-iii

Solution

a) Aspergillus niger is the most commonly used microbe for the industrial production of Citric acid.
b) Cyclosporin is most commonly produced by submerged fermentation of the clostridium species.
c) Lovastatin and compastin are some natural statins produces from Monascus species by fungal fermentation process.
d) Production of butyric acid by Clostridium tyrobutyricum is the most widely used method for butyric acid production by large scale fermentation process.
