2. MEANING OF MICROBIOLOGY
 Microbiology : from Greek word
 μῑκρος, mīkros, :"small";
βίος, bios, :"life";
-λογία, -logia
 Branch of biology
that dealing with
microscopic forms of life cells.

4. DEFINATION OF MICROBIOLOGY
• MICROBIOLOGY : study of microorganisms
• Unicellular : single cell
• Multicellular :cell colony
or
• Acellular : lacking cells.

5. Biological characteristics of microorganisms
MOROPHOLOGY
NUTRITION
 PHYSIOLOGY
 REPRODUCTION
GROWTH
METABOLISM
PATHOGENESIS
 ANTIGENICITY
 GENETIC PROPERTIES.

6. TYPES OF MICROORGANISMS
 EUKARYOTIC:
microorganisms possess membrane
bound organelles
 Include :FUNGI & PROTISTS
PROKARYOTIC—
microorganisms: conventionally classified as
lacking membrane-bound organelles
Include : BACTERIA & ARCHAEA
VIRUS :variably classified as organisms,
considered as a either as very simple
microorganisms or very complex molecules.

7. APPLICATION OF MICROBIOLOGY
 INDUSTRIAL FERMENTATION
 Antibiotic production
 Tissues Engineering
 DRUG delivery
 biotechnologically
important Enzymes such as
Taq Polumerase
 Industrial production
of Amino Acids :eg
 Alcohol, Vinegar and Dairy
Products Production
 BIOPOLYMER Production
 Microbial Biodegradation
 Various strains of non-
pathogenic Clostridia can
infiltrate and replicate
within solid tumors.:
Clostridial vectors.
