1. Economic importance of bacteria

Khushbu’s Microbiology

2. Bacteria :microorganisms
 Bacteria :helpful to the other living organisms
 Nutrition,
 health,
 or any other support without causing any
harmful effects.
 Bacteria : economically important as
these microorganisms are used by humans for
many purposes.

3. Beneficial uses of bacteria
• Production of traditional foods :
 Yogurt
 Cheese
 vinegar.
• Agriculture :
 Compost and fertilizer production.
• Bacteria :
 in genetic engineering
 genetic changes.

4. Useful bacteria
 Genetic engineering :
production of human insulin and human growth hormone
 Biotechnology :
Bacteria are important in the production of many dietary
supplements and pharmaceuticals.
 Food processing :
Sourdough bread is made
to rise by fermentation,
with a leaven that consists of bacteria
, often combined with wild yeast
Enzymes

5. Useful bacteria
 Bioremediation :remove pollutants from
contaminated water, soil and subsurface material.
Mega Borg Oil Spill
100 pounds of bacteria
were sprayed over an acre
of the oil slick to break down
the hydrocarbons
present into
more benign by-products.

capable of degrading oil in seawater

6. Industry importance of bacteria
 Fiber industry:
Bacteria like : clostridium butyrcum is used in
the retting of flax, sunn hemp to extract the
clear fiber.
 Tea and tobacco:
Micrococcus & Bacillus megatherium are used
in the curing of tea and tobacco.

7. Industry importance of bacteria
 Sterilization: This is a process to eradicate
microbial contamination from finished
products.
 Few bacteria : biological indicators
for sterilization validation.
 These bacteria are available commercially as
strips containing spores.

8. Medicine (probiotics)
Antibiotics : E. coli : used for produce
D-amino acids such as D-p-hydroxy phenylglycin,
an important intermediate for synthesis of the
antibiotic amoxicillin.
 Insulin,
 Other medicines are obtained from them.
 Escherichia coli : used for commercial
preparation of riboflavin and vitamin K.

9. Agriculture importance
Bio-pesticides and fertilizers.
 Pest control :
Bacteria can also be used in the place
of pesticides in biological pest control
 Nitrification: Rhizobium bacteria, living in root
nodules of leguminous plant symbiotically,
helps in fixing atmospheric nitrogen.
