(b) Propionibacterium shermanni
(c) Aspergillus niger
(d) Trichoderma polysporum
(e) Acetobacter aceti
(f) Streptococcus

Hint:

Microorganisms like Saccharomyces cerevisiae, Propionibacterium shermanni, and others are essential in various industrial processes like fermentation, biocontrol, and food production.

Answer 1

(a) Saccharomyces cerevisiae.
Saccharomyces cerevisiae is commonly used in the production of bread, beer, and wine. It is a type of yeast that helps in the fermentation process.
(b) Propionibacterium shermanni.

(c) Aspergillus niger.
Aspergillus niger is used to produce citric acid, which is widely used in food and beverage industries as a preservative and flavoring agent.
(d) Trichoderma polysporum.
Trichoderma polysporum is used in biocontrol to protect plants from fungal pathogens. It is a natural pesticide that is used in agriculture.
(e) Acetobacter aceti.
Acetobacter aceti is used in the production of vinegar. It converts alcohol into acetic acid, which gives vinegar its sour taste.
(f) Streptococcus.
Streptococcus is used in the production of dairy products such as yogurt and cheese. It aids in the fermentation process to make these products.
