Biology · MICROBES IN HUMAN WELFARE
हिन्दीConsider the following statements regarding microbes in industrial products: (A) Production on an industrial scale requires growing microbes in very large vessels called fermentors. (B) Antibiotics are 'pro life' with reference to human beings, meaning they promote pathogen growth. (C) The chemical substance penicillin was named after the mould Penicillium notatum. (D) Lipases are used in detergent formulations to help remove oily stains from laundry. Which of the above statements are correct?
Correct answer · Option 3
(A), (C) and (D) only
Explanation
Statement (A) is correct because large-scale production of industrial products involving microbes requires very large vessels known as fermentors. Statement (B) is incorrect because antibiotics are 'pro-life' with respect to humans (meaning they favor human life by being life-against for pathogens, i.e., they kill or inhibit disease-causing bacteria). Statement (C) is correct as penicillin was extracted from and named after the mould Penicillium notatum (though later Penicillium chrysogenum was used for higher yields). Statement (D) is correct because lipases are utilized in detergent formulations to efficiently remove oily stains from laundry. Therefore, statements (A), (C), and (D) are correct.
