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
Industrial microbiology
Uses microorganisms, typically grown on a large scale, to produce valuable commercial products…………
Industrial microbiology
Actual reactions carried out by microorganisms in industrial microbiology
Biocatalaysis
List the role of microbiologist
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.
Industrial microorganisms must?
- produce in high yield
- Grow rapidly on inexpensive culture
- be gentic manipulation
- nonpathogenic
When the reactions lead to the formation of a more complex substance, that particular form of metabolism
anabolism, and the pathway an anabolic pathway.
the series of reactions lead to less complex compounds the metabolism is described as
catabolism.
compounds involved in a metabolic pathway are called
intermediates
When a microbial culture is inoculated into fresh medium, growth begins after a period of time called
lag phase.
If an exponentially growing culture is transferred into the same medium under the same conditions of growth, there will be no lag. T/F?
T
there is no net increase or decrease in cell number and thus the growth rate of the population is zero (cryptic growth).
stationary phase
the rate of cell death is much higher than the rate of cell division
decline phase / Death phase
The metabolites which are required for the growth and maintenance of cellular function are called
primary metabolites
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
secondary metabolites
are the compound produced during the growth phase.
Primary metabolites
During the period of trophophase ( primary metabolites), the exponential growth of the microorganisms end. T/F?
F, exponential growth start
As soon as the exponential phase ends, the process enters into the another phase called as
idiophase or secondary metabolism.
are produced by very specific microorganisms only, mainly antibiotics
Secondary metabolites
series of chemical reactions involved in converting a chemical (or a metabolite) in the organism into a final product is known as
a metabolic pathway.
It starts when all the required nutrients are present in the medium for an organism to grow.
primary metabolism or trophophase.
These are the important compounds requires to sustain the process of cell growth, Vitamins, nucleosides, amino acids
essential metabolites.
This phase occurs at the period of the limited nutrient or when there is the accumulation of the waste products.
idiophase or secondary metabolism.
