what OOW is bioluminescent
vibrio fischeri (luciferase causes this)
what does vibrio fischeri gain from symbiosis
what does squid gain
bacteria- the squid feeds the bacteria
squid- protection from predators since it hunts at night the luminescence makes it appear like the mood to predators
what OOW has weird shape (not rod, not cocci) and why
Mycoplasma pneumoniae (schmoo shaped due to lack of peptidoglycan and instead has chloesterol/endoskelaton??)
define bioluminescence
emits light due to chemical reaction (cell density triggers rxn)
what OOW is a marine bacterium
vibrio fischeri
what oow is squid symbiont
vibrio fischeri
what oow has luciferase
vibrio fischeri
what oow only produces light at high cell density
vibrio fischeri
what oow has quorum sensing (cell communication that allows cells to detect one another)
vibrio fischeri
what oow has chemical recognition between squid and bacteria
vibrio fischeri
