Contaminations Flashcards
1
Q
how are biofilms formed
A
initial attachment, irriversible attachment, microcolony formation, maturation, dispersal
bacteria secrete polysaccharides and sit in their slime substance
2
Q
bacterial sporulation
A
used by gram-positive bacteria when nutrients are depleted
spores are resistant to heat, radiation, dessication, chemical agents
3
Q
process of sporulation
A
asymmetric division -> engulfs -> cortex forms -> spore coat -> cell lysis -> germination
