Silicibacter pomeroyi
• Breaks DMSP (dimethysulfoniopropionate) down to make DMS (sulfur compound that increases sulfur supply in the atmosphere)
• In the atmosphere, DMS oxidizes into sulfuric acid and methanesulfuric acid
• DMS and DMSP draws in water molecules and forms clouds, which regulates the climate system
• Spreads the radiation coming from the sun

Thiomargarita namibiensis
• Microbe which is visible to the human eye; as big as a period at the end of a sentence.
• Sulfide-eating bacteria which removes poisonous gases from the ocean making the water clean for marine life.
• Recycling of carbon, nitrogen, and sulfur are necessary to maintain the Earth’s environment and the life it supports.

Brucella melitensis
• Can cause Brucellosis, a fatal disease that affects mainly animals like goat and sheep.
• Bacteria can transfer to humans through contaminated or poorly or unpasteurized milk and cheese.
• Bacteria serves as primary microbial decomposers which is necessary in the recycling of nutrients.

Symbiodinium microadriaticum
• Symbiodinium is a bacteria that is unicellular and has circular shape.
• The bacteria found in the coral takes in light and oxygen from the water and the bacteria then lower the carbon dioxide in the the water.

Prochlorococcus marinus

- Photosynthesizes to grow- Regulates population with
viruses or phages- Base of food web
(everything eats it)- Many throughout water
column*; greatly harvests carbon dioxide and releases oxygen (about two times more carbon dioxide in atmosphere without Prochlorococcus marinus)

Prochlorococcus
• The Prochlorococcus is important to the earth because it accounts for half of the photosynthesis on the earth.
• It removes twice as much carbon dioxide from the atmosphere than all the land bound autotrophs.

Emiliana huxleyi
• Phytoplankton• Autotrophic• Calcium carbonate platelets or
coccoliths surround the exterior of the cell
• Coccolith blooms are highly reflective, reflecting light and heat back into space, rather than heating the ocean
• Draws CO2 out of atmosphere, uses it to produce coccoliths, then it sinks to the bottom of the ocean, reducing greenhouse gasses (http://microbewiki.kenyon.edu/index.php/Emiliana) http://www.soes.soton.ac.uk/staff/tt/
