Preparation of Culture Media, Inoculation & Incubation Techniques Flashcards
Increase in cell number through binary fission
Microbial growth
cell simply splits into two cells, producing two identical cells
Binary fission
Difference of binary fission from mitosis
No mitotic spindle form
the average time between two consecutive generations in the lineages of a population
generation time
generation time E.coli
30 to 180 mins
generation time M. tuberculosis
12 hours
T. pallidum
33 hours in rabbit testes
M. leprae

Cocci synthesize new cell walls
septal region
Synthesize new cell wall entire surface of the cell
Rod shape bacteria
