8 Questions
During which phase of bacterial growth does cell division stop due to nutrient depletion and toxic product accumulation?
Stationary phase
What characterizes the Log or Exponential phase of bacterial growth?
Smaller cells, stain uniformly
How are bacterial counts affected in the Stationary phase?
Remain stationary due to equilibrium between dying and new cells
What method can be used to obtain the Total Count of bacterial cells?
Direct counting under a microscope using counting chambers
Which phase is characterized by the production of autolytic enzymes leading to a decrease in population?
Phase of Decline
What is the key feature of the Lag phase of bacterial growth?
No increase in cell size
Which method measures the number of living bacterial cells specifically?
Viable cell count method
What happens to the number of living and dead cells in the Total Count method?
Both living and dead cells are counted
