What do you mean by “Nutrient repression”?(a) Inhibition of unwanted enzyme production(b) Production of unwanted enzymes(c) Inhibition of cell nutrients(d) Production of wasteThis question was posed to me during an interview.Asked question is from Large topic in portion An Overview of Biological Basics & Enzymes of Bioprocess Engineering |
Answer» RIGHT answer is (a) Inhibition of UNWANTED enzyme production For explanation: The native metabolism of microorganism is so devised that there occurs no production of unnecessary enzymes. In other words, the MICROORGANISMS do not synthesize enzymes that are not required by them, since this is a wasteful exercise. The inhibition of unwanted enzyme production is done by nutrient repression. The nutrients may be CARBON, NITROGEN, phosphate or sulfate suppliers in the growth medium. For large scale production of enzymes, nutrient repression must be overcome. |

Which of the following is not included in immobilization process?(a) Absorption(b) Adsorption(c) Entrapment(d) AffinityI have been asked this question in an interview.Origin of the question is Large in portion An Overview of Biological Basics & Enzymes of Bioprocess Engineering |
Answer» RIGHT answer is (a) Absorption The explanation is: DESPITE their excellent catalytic capabilities, enzymes and their properties must be improved prior to industrial implementation in many cases. Some aspects of enzymes that must be improved prior to implementation are stability, activity, inhibition by reaction PRODUCTS, and selectivity towards non-natural substrates. This may be accomplished through immobilization of enzymes on a solid material, such as a porous support. Immobilization of enzymes greatly simplifies the recovery process, enhances process control, and reduces operational costs. Many immobilization TECHNIQUES exist, such as adsorption, COVALENT binding, affinity, and entrapment. |
