3. Microbe is a microscopic
organism, which may be a single
cell or multicellular organism. The
study of microorganisms is called
microbiology.

4. But Microbes useful in our
daily life, Industrial life etc.

6. 1: A common example is curd from milk.
Lactobacillus is that microbe which convert the
milk into curd.
It is also known as lactic acid bacteria.

7. IN OUR STOMACH TOO, THE LAB
PLAY VERY BENEFICIAL ROLE IN
CHEKING DISEASE CAUSING
MICROBES.

9. 1: Used for making Dosa, Idli and chole
bhature.
It is due to the production of CO2.

11. 

For making Swiss cheese. There is large holes
in Swiss cheese due to larger amount of CO2.
Roquefort cheese are ripened by growing a
specific fungi on them, which gives a particular
flavor.

13. Industrial fermentation

14. Even in industry, microbes
are used to synthesize a
number
of
products
valuable to human beings.
Production
on
an
industrial scale, require
growing microbes in very
large
vessel
called
fermentors.

15. Microbes especially yeast have
Same yeast saccharomyces
been
used
from
cerevisiae used for makingtime
immemorial for the production
bread and commonly
of beverages like wine, beer,
called brewer’s yeast.
whisky, brandy or rum

16. Anti means ‘against’
Bio means ‘life’.
Antibiotics are the chemical
substance, which are produced by
some microbes and can kill or retard
the growth of other microbes. Ex
like penicillin.

17. After penicillin, other
antibiotics were also purified
form other microbes.
Antibiotics
have
greatly
improved our capacity to treat
deadly disease such as plague,
whooping cough(kali khansi)
and leprosy(kusht rog). Which
used to kill millions all over
the globe. Today, we can’t
imagine a world without
antibiotics.

18. Microbes are also used for commercial and
industrial production of certain chemicals like
organic acids, alcohols and enzymes.
1 :- Aspergillus niger(a fungus) produce citric acid
2:-Acetobacter aceti(a bacterium) produces acetic
acid.
3:- yeast for the production of ethanol.
4:- lactobacillus for the production of lactic acid.

19. Microbes are also used for the production of
Enzymes.
1:Lipases are used in detergent formulations and
are helpful in removing oily stains from the
laundry.

20. Have you ever noticed the bottled fruit juices bought
from the market are clearer as compared to those
made at home why?
Proteases and Pectinases are the reason for above
question.

21. Strepetokinase produced by strepetococcus and modified
by genetic engineering is used as a ‘clot buster’ for
removing clots from the blood vessels of patients
who have undergone myocardial infection leading to
heart attack.

22. Trichoderma polysporum:CyclosporinA,
that
is
used
as
an
immunosuppressive agent in organ-transplant
patients.

23. Monascus purpureus-:
Statin is used for blood cholestrol lowering agents. It
acts by competitively inhibiting the enzyme
responsible for the synthesis of cholestrol.
