Microbial Metabolism
|
the means by which a microbe obtains the energy and nutrients (e.g. carbon) it needs to live and reproduce
|
|
|
Microbial genetics
|
It studies the genetics of very small
(micro organisms.) This involves the study of the genotype of microbial species and also the expression system in the form of phenotypes.It also involves the study of genetic processes taking place in these micro organisms i.e., recombination etc. |

|
|
Microbial ecology
|
is the ecology of microorganisms: their relationship with one another and with their environment.
|
It concerns the three major domains of life — Eukaryota, Archaea, and Bacteria — as well as viruses.
|
|
Beneficial Applications
Why study microbiology |
causative agents of infectious diseases
|
|
|
Beneficial Applications
Why study microbiology |
Normal flora
Beneficial metabolic functions Antagonistic effect - prevents invasion pathogens, over growth of potential pathogens |
Normal flora vs. identification pathogen
|
|
two basic cell types
(all living cells) |
Eukaryotic (true nucleus)
more complex Prokaryotic (pre nucleus) simpler smaller |
|
|
Eukaryotic cells
|
1 Possess a true Nucleus
Nuclear material surrounded by a nuclear membrane. Nuclear material organized into paired chromosomes. Nuclear membrane (DNA) associated with proteins called histones form the chromosomes Nucleus contains nucleolus the sites of ribosome synthesis |
|
|
Eukaryotic cells
|
2.Internal structure more complex - contains organelles - each have a specific function.
|
|
|
Eukaryotic cells
|
3. Cytoplasmic streaming - continuous movement of the cytoplasm.
4.Cell membranes contain complex lipids - sterols (cholesterol). |
|
|
Eukaryotic cells
|
5.Cell walls
Occur only on plant cells, fungi Composed of cellulose, chitin. |
|
|
Eukaryotic cells
|
Division occurs by mitosis, meiosis.
|
|
|
PROKARYOTIC CELLS
|
No “true”nucleus nucleoid
No nuclear membrane. No paired chromosomes. No histones. No nucleolus. No organelles. No cytoplasmic streaming |
|
|
PROKARYOTIC CELLS
|
Cell membrane contains no sterols.
Cell walls All typical prokaryotic cells possess cell wall Composed of peptidoglycan (murein). |
|
|
PROKARYOTIC CELLS
|
Division - binary fission.
