Question 1

is the study of the large-scale and profit motivated production of microorganisms or their products for direct use, or as inputs in the manufacture of other goods

Answer 1

Industrial microbiology

Question 2

Uses microorganisms, typically grown on a large scale, to produce valuable commercial products…………

Answer 2

Industrial microbiology

Question 3

Actual reactions carried out by microorganisms in industrial microbiology

Answer 3

Biocatalaysis

Question 4

List the role of microbiologist

Answer 4

a. the selection of the organism to be used in the processes
b. the choice of the medium of growth
c. the determination of the environmental conditions
d. quality control
e. proper custody of the organisms
f. improvement of the performance of the microorganisms by genetic manipulation or by medium reconstitution.

Question 5

Industrial microorganisms must?

Answer 5

• produce in high yield
• Grow rapidly on inexpensive culture
• be gentic manipulation
• nonpathogenic

Question 6

When the reactions lead to the formation of a more complex substance, that particular form of metabolism

Answer 6

anabolism, and the pathway an anabolic pathway.

Question 7

the series of reactions lead to less complex compounds the metabolism is described as

Answer 7

catabolism.

Question 8

compounds involved in a metabolic pathway are called

Answer 8

intermediates

Question 9

When a microbial culture is inoculated into fresh medium, growth begins after a period of time called

Answer 9

lag phase.

Question 10

If an exponentially growing culture is transferred into the same medium under the same conditions of growth, there will be no lag. T/F?

Answer 10

T

Question 11

there is no net increase or decrease in cell number and thus the growth rate of the population is zero (cryptic growth).

Answer 11

stationary phase

Question 12

the rate of cell death is much higher than the rate of cell division

Answer 12

decline phase / Death phase

Question 13

The metabolites which are required for the growth and maintenance of cellular function are called

Answer 13

primary metabolites

Question 14

metabolites which are not required for the growth and maintenance of the cellular functions and are the end products of the primary metabolism are called

Answer 14

secondary metabolites

Question 15

are the compound produced during the growth phase.

Answer 15

Primary metabolites

Question 16

During the period of trophophase ( primary metabolites), the exponential growth of the microorganisms end. T/F?

Answer 16

F, exponential growth start

Question 17

As soon as the exponential phase ends, the process enters into the another phase called as

Answer 17

idiophase or secondary metabolism.

Question 18

are produced by very specific microorganisms only, mainly antibiotics

Answer 18

Secondary metabolites

Question 19

series of chemical reactions involved in converting a chemical (or a metabolite) in the organism into a final product is known as

Answer 19

a metabolic pathway.

Question 20

It starts when all the required nutrients are present in the medium for an organism to grow.

Answer 20

primary metabolism or trophophase.

Question 21

These are the important compounds requires to sustain the process of cell growth, Vitamins, nucleosides, amino acids

Answer 21

essential metabolites.

Question 22

This phase occurs at the period of the limited nutrient or when there is the accumulation of the waste products.

Answer 22

idiophase or secondary metabolism.
