many types of microbes (especially bacteria) reproduce via binary fission
what happens during the process of binary fission? microbes double
prokaryotes: bacteria and archaea reproduce by binary fission
only group that has a nucleotide (microbes DNA)
septam (wall)
generation time (aka doubling time) the amount of time it takes a population of microbes to double in size

important concept in microbiology determining how many microbial cells are present after a specific number of generations/
doubling events
important formula for finding out how many bacteria would be initial cells x 2 ^ number of generations
present in a test tube after a certain amount of hours number of generations= total time in tube/ generation time
what are the four phases of microbial growth? lag phase
log (exponential) phase
stationary phase
death phase
lag phase no growth; microbes adjust; synthesize enzymes needed to eat
log (exponential) phase maximum growth
stationary phase growing microbes= dying microbes
nutrients go away; waste builds
death phase dying >>> growing
nutrients gone
waste levels very high
what are most pathogens? mesophiles
what is the human body temperature? 98.6 degrees F -> 37 degrees C
what is the temperature psychrophiles can grow? -5 to 20 degrees C
psychrophiles found in freezer or fridge
some can grow diseases such as listeria
