Binary Fission Most common form of bacterial reproduction
4 Basic Steps 1. Growth of cell size
2. Replication of DNA
3. Division of cytoplasm
4. Septum formation & cell division
Cytokinesis Division of cytoplasm
Z Ring Assembly FtsZ assembles Z ring to form divisome
Divisome Cell division apparatus
Generation Time (Doubling Time)-time it takes to double the
population
Lag Phase Cells adjust to culture medium; no change in
population
Log Phase Binary fission occurs; cell replication > cell death

Stationary Phase Resources become depleted; cell respiration=cell
death
Death Phase Endospores can form; cell replication < cell death
Close System Cultures Have finite resources
Open System Cultures -Nutrients and air are replenished
-Dead cells and waste are removed
-Beneficial for industrial microbiology
Microscopic Cell Count Cells are counted under a microscope using a laser
etched slide
Fluorescence Staining -Cells are counted under a microscope or flow
cytometer
-Red stain binds to damaged cells
Viable Cell Counts -Samples are diluted and grown on solid media
Countable Range 30-300 CFU/ml
Optical Density -Measured with spectrophotometer
-Light is passed thru culture and measured on
other side
Steps of Biofilm Formation 1. Attachment of planktonic cells
2. Cells become sessile
3. Growth & Division on substrate
4. Production of extracellular polymeric substance
5. Attachment of secondary colonizers & dispersion
Quorum Sensing Cell to cell communication
