BACTERIA AND THEIR
SYMBIOTIC RELATIONSHIP
Dan, Raza, Yuhui
Bioluminescent Bacteria
• Genera Vibrio and photomicrobium
• Bacteria that look like curved rods about 1 to 3 microns long
• They have symbiotic relationships with flashlight fish, angler fish
and bobtail squid
• Use oxygen to produce light
• (FMNH2 + O2 + RCHO
FMN +RCOOH + H2O + Light)
• Enzyme luciferase
• Bacteria light production controlled by Lux operon
Methanogen
• Archaea
• Uses hydrogen gas to
reduce carbon dioxide to
methane
(chemoautotroph)
• Obligate Anerobe
• Swamps, marshes, animal
guts
• Some are extremophiles
Ruminant
• Even-toed hoofed mammalian herbivore
• Have a digestive chamber called the rumen which contains microbes
that break down cellulose
(Ex: Methanogen)
• 15-20% global production of methane

Bioremediation
• Used to help degraded
ecosystems and
environments
• A strategy
of restoration ecology with
the use of living organisms
such as: prokaryotes, fungi,
or plants to
detoxify environments
• Genetic engineering is
also used along side nutrient
supplementation to maximize
growth
• Augmenting ecosystem
Deincoccus
radiodurans
