bacteria and their symbiotic relationship

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
