Flashcards in Lecture 17 - Ch 26 - Microbial Growth Control Deck (29)
The killing or removal of all viable organisms within a growth medium
Effectively limiting microbial growth
The treatment of an object to make it safe to handle
Directly targets the removal of all pathogens, not necessarily all microorganisms
resistant cells that Can survive heat that would rapidly kill vegetative cells
Sterilization method where high temperatures denature macromolecules
sealed device that uses steam under pressure
the process of using precisely controlled heat to reduce the microbial load in heat-sensitive liquids
this sterilization method avoids the use of heat on sensitive liquids and gases
chemical control that causes an arrest in growth
chemical control that kills the bacteria and leaves the dead cell
chemical control that kills the bacteria and lyses the cell
the smallest amount of an agent needed to inhibit growth of a microorganism
minimum inhibitory concentration (MIC)
beta-lactams Inhibit enzymes that catalyze __________.
which antiobiotics Inhibit enzymes that catalyze transpeptidation of PG
which antibiotics inhibit enzymes that catalyze transglycocylation
bind to membrane phospholipids and interfere with membrane function
prevents the binding of 50S ribosome to 30S.
what is an example of a glycopeptide?
what are examples of aminoglycosides?
gentamicin and kanamycin
Prevents binding of tRNA to 30S
prevents 50S function
what are examples of macrolides
erythromycin, azithromycin, lincomycin
Bind to and inhibit DNA gyrase
give an example of a fluoroquinolone
which antibiotics target DNA synthesis
Binds to and inhibits RNA polymerase
Which antibiotics treat TB?
