Objectives

• At the end of this class, the students should be
  able to
• Recognize the significant applications of
  microorganisms in agriculture, industry, health
  and molecular biology research
• Cite examples of industrial products of microbial
  biotechnology useful to man

3
Microorganisms

• Minute living things unseen by the naked eyes
• Diverse and unique life form
• Ubiquitous in nature live in soil, water, food,
  animal intestines as well as in extreme settings
  such as glaciers, hot springs and deep-sea
  thermal vents

4
Microorganisms
Protozoan
Algae
Yeast
Mold
Archaeon
Bacterium
Virus
5
Microorganisms

• Used in the production of fermented foods (eg.
  beer, wine, bread etc.)
• Used in the production of enzymes and bioactive
  compounds for medical and pharmaceuticals
• Used in bioremediation and waste treatment

6
Microbial Biotechnology

• Application of scientific and engineering
  principles to the processing of materials by
  microorganisms to create useful products or
  processes.
• Microorganisms utilized may be natural isolates,
  laboratory selected mutants or microbes that have
  been genetically engineered using recombinant
• DNA methods.

7
Microbial Biotechnology

• Deals with the prevention of deterioration of
  processed or manufactured goods, environmental
  protection and with waste disposal system.
• Production of antibiotics, organic acids and
  enzymes by fermentation of natural microbes,
  laboratory selected mutants or microbes
  genetically engineered using recombinant DNA
  methods.

8
Microbial Biotechnology in Foods and Agriculture

• Benefits
• development of genetically engineered plants with
  internal resistance to drought, frost, insect
  pests and infestation
• reduction in dependency of plants on chemical
  fertilizers and identification of alternatives to
  expensive fertilizers
• replacement of dangerous chemical pesticides with
  microbial pesticides to manage and control the
  problem of pests

9
Microbial Biotechnology in Foods and Agriculture

• reduction in the reliance on chemical treatments
  to control weeds by engineering herbicide
  tolerance into crops
• production of products that have high yield and
  enhanced nutritional value
• development of novel biomass products as
  foodstuffs, using organisms such as algae, fungi,
  bacteria and yeast.
