Question

Match the following organisms with the products they produce.
(a)Lactobacillus (i) Cheese
(b)Saccharomyces cerevisiae (ii) Curd
(c)Aspergillus niger (iii) Citric acid
(d)Acetobacter aceti (iv) Bread
                                                                         (v) Acetic acid
Select the correct option
(A)(a)-(ii), (b)-(iv), (c)-(v), (d)-(iii)
(B)(a)-(ii), (b)-(iv), (c)-(iii), (d)-(v)
(C)(a)-(iii), (b)-(iv), (c)-(v), (d)-(i)
(D)(a)-(ii), (b)-(i), (c)-(iii), (d)-(v)

Answer 1

Hint: Industrial microbiology is a branch of biotechnology and microbiology, which mainly deals with the study of varied microorganisms and its applications in industrial processes. In large-scale industrial processes, microbes are widely used to synthesize a number of products valuable to human beings.

Complete answer:
Microbes are utilized in the production of several household and industrial products –
Lactobacillus – Production of curd
Saccharomyces cerevisiae – Bread making
Aspergillus niger – Citric acid production
Acetobacter aceti – Acetic acid

Additional Information: The lactobacillus is a very common bacteria which is one of the most used bacteria in our daily life. Lactobacillus helps to supply carboxylic acid which helps to convert milk to curd. Saccharomyces cerevisiae is a very commonly used fungus. This fungus is employed to supply carbon dioxide a bit like yeast which helps to supply fluffy bread. Aspergillus niger is a commonly used industrial fungus. This fungus is employed to supply very high-grade industrial cheese. Acetobacter acetic is an industrially used bacteria. This bacteria is used to produce both Citric Acid and acetic acid.
So, the correct option is ‘(a)-(ii), (b)-(iv), (c)-(iii), (d)-(v)’.

Note: Food is an important basic substance for human beings which provides the nutrients for survival. Food processing is the process of creating food from different raw materials through physical and chemical processes. Household and industrial food manufacturing are the two important sources of developed food. Microorganisms are very tiny in size. They are not visible to the naked eye. Microorganisms are present altogether in various environmental sources like soil, air, water, animal body, and plant, etc.
