MICROBIAL GROWTH PHASES II Flashcards
kills bacteria by injuring the cell membrane which results to leakage of cell’s content
phenol/phenolic
CHEMICAL METHODS OF MICROBIAL CONTROL
phenol/phenolic
alcohols
halogens
heavy metals
aldehydes
peroxygens
surface-active agent
gaseous sterilant
organic acid
biguanides
results in protein denaturation and lipid dissolution
alcohols
oxidizing agent
halogens
types of halogens:
iodine - wound aseptic
chlorine - water disinfection
fluorine - used in toothpaste
used in protein and enzyme denaturation
heavy metals
types of heavy metals with meaning
copper sulfate
silver nitrate
mercury
thimerosal
zinc oxide nanoparticles
algicide in swimming pool
Bordeaux mixture
currently used for neonatal gonorrhea
erythromycin
old Merthiolate, new Merthiolate
thimerosal, benzalkonium chloride
very effective antimicrobial
aldehydes
types of aldehydes
formaldehyde
glutaraldehyde
preservative (used in embalming)
formaldehyde
less irritating than formaldehyde
glutaraldehyde
antiseptic/irrigating agent for deep wound
hydrogen peroxide
