MICROBIAL GROWTH AND REPRODUCTION Flashcards
Characteristic of Growth of a Unicellular Microbial Culture
CHARACTERISTIC:
No increase in cell no.
Lag
Characteristic of Growth of a Unicellular Microbial Culture
CHARACTERISTIC:
Cells increase in size
Lag
Characteristic of Growth of a Unicellular Microbial Culture
CHARACTERISTIC:
Cells physiologically active and synthesizing new enzymes to adapt to new environment
Lag
Characteristic of Growth of a Unicellular Microbial Culture
CHARACTERISTIC:
Balanced Growth
Exponential or Logarithmic (log)
Characteristic of Growth of a Unicellular Microbial Culture
CHARACTERISTIC:
Cells are mostly nearly uniform
Exponential or Logarithmic (log)
Characteristic of Growth of a Unicellular Microbial Culture
CHARACTERISTIC:
Peak time of physiological activities
Exponential or Logarithmic (log)
Characteristic of Growth of a Unicellular Microbial Culture
CHARACTERISTIC:
Accumulation of inhibitory metabolic products & depletion of nutrients
