Microbiology Miscellaneous

  1. Microbes bring about biological transformation of xenobiotic compounds by
    1. degradation ​​
    2. conjugation ​​
    3. ​ detoxification
    4. all of these
Correct Option: D

microbes use replication procedure for xenobiotic compound transformation. A xenobiotic is a chemical which is found in an organism but which is not normally produced or expected to be present in it. It can also cover substances which are present in much higher concentrations than are usual. Specifically, drugs such as antibiotics are xenobiotics in humans because the human body does not produce them itself, nor are they part of a normal diet. However, the term xenobiotics is very often used in the context of pollutants such as dioxins and polychlorinated biphenyls and their effect on the biota, because xenobiotics are understood as substances foreign to an entire biological system, i.e. artificial substances, which did not exist in nature before their synthesis by humans. ​
