3. Key contents
1. Introductory discussion about
industrial microbiology
2. History of Industrial microbiology
3. Application and case study

4. To know about industrial
microbiology
To identify the practical
implications

6. branch of biotechnology that
applies microbial sciences to
create industrial products in mass
quantities
There are multiple ways to
manipulate a microorganism in
order to increase maximum
product yields.

7. Industrial microbiology came into
existence, primarily, based on a
naturally occurring microbiological
process called fermentation

8. Early fermentation process
leavening
of bread
retting
of flax,
preparation of vinegar from wine

9. Case study
Use of microorganisms in solid waste
management
The growth of any or all types of
microorganisms in a given industrial
waste disposal system will depend
upon the chemical characteristics of
the industrial waste,

10. fungi
(mushroom)
Fungi play an
important role in the
stabilization of
organic wastes
fungi can metabolize almost every
type of organic compound found in
industrial wastes.

11. The filamentous nature of most of
the fungi found in industrial wastes
makes them undesirable
they do not form a tight compact
floc and settle easily
filamentous fungi predominate over
the bacteria at low oxygen tensions,
at low pH, and at low nitrogen

12. Under reduced oxygen levels,
metabolism does not proceed to
carbon dioxide and water but stops
with the formation of organic
alcohols, aldehydes, and acids
If the system lacks sufficient buffer,
the organic acids depress the pH to
the more favorable range for fungi.

13. Fungi require less nitrogen
In nitrogen deficient wastes, the
fungi are able to synthesize more
active masses of protoplasm from
the wastes than are the bacteria
and predominate.

14. Under normal environmental
conditions fungi will be present and
will aid in the stabilization of the
organic matter
Example Agarics
bisporus

15. Application
Medical and Pharmaceutical
Industry application
Food industry
textile
industry
Agricultural
application
Genetic engineering

16. Medical &Pharmaceutical
application
production of new drugs synthesized in a specific
organism for medical purposes.
Antibiotics
Vaccines

17. Antibiotics
Antibiotics produced by microbes are regarded
was one of the most significant discoveries of the
twentieth century and have made major
contributions towards the welfare of human
society.
Penicillins: penicillin and
amoxicillin.
Cephalosporins :cephalexin
(Keflex)

18. Actinomycetes
in the genus
Streptomycin
(e.g.
Tetracycline,
Streptomycin,
Actinomycin D)

19. biological
preparation that
provides active
acquired immunity
to a particular
disease

20. chickenpox
vaccine
Yellow fever.
Rotavirus.

21. Food microbiology is the study of
the microorganisms that inhibit,
create, or contaminate food,
including the study of
microorganisms causing food
spoilage

22. Fermented milk products:
Lactobacillus, Lactococcus,
Bifidobacterium.
Kefir
buttermilk.
Sour
milk

23. yogurt
Lactobacillus bulgaricus
Streptococcus thermophilus

24. Beverages
Microbes especially yeast
have been used from time
immemorial for the
production of beverages
like wine, beer, whiskey,
brandy or rum. For this
purpose,
yeast

26. Microbes in textile industry
Microbes are the tiniest creatures not seen by the
naked eyes. They include a variety of
microorganisms
like bacteria, fungi, algae and virus
staphylococus aureus
E-coli

27. staphylococus aureus
E-coli

28. Soil microorganisms
Bacteria :more dominant group of microorganisms
Actinomycetes - intermediate group between
bacteria and fungi.
Fungi:Aspergillus, Mucor, Penicillium
Trichoderma, Alternaria, Rhizopus. Algae
Protozoa:They are regulating
the biological equilibrium in soil.

29. Biopesticide
Bio pesticide is a pesticide
derivatized from a living
organism or natural
occurring substances

30. Bacillus thuringiensis

31. Microbial industrial genetic
engineering
The main use of microbes in the
field of genetic engineering is as
"Vector".
Vectors means that some microbes carry the
gene of interest to the target genome

32. The recombinant DNA of the
vector is called plasmid DNA.
Munching bacteria is the
genetically engineered bacteria
that are used for cleaning oil
spills

35. Concluding remarks
Industrial microbiology has
impact in our industrial
sector
