F ILL IN THIS TABLE WITH INFO FROM THE FOLLOWING 3 SLIDES Bacteria TypeDescriptionExample/Info Aerobic Anaerobic Facultative Aerobe

Aerobic – thrive in the presence of oxygen and need it for their continued growth and existence Obligate aerobes – require oxygen for survival s.html

Anaerobic – cannot tolerate gaseous oxygen, such as those bacteria which live in deep underwater sediments, or those which cause bacterial food poisoning Obligate anaerobes – cannot live in the presence of oxygen T_EID/lectures/tetanus-pathogen.html

Facultative anaerobes - prefer growing in the presence of oxygen, but can continue to grow without it.

B ACTERIA N UTRITIONAL P REFIXES Hetero = Other Auto = Self Photo = Light Chemo = Chemical Troph = Nourishment Bacteria have 2 main nutritional needs, a source of carbon to build molecules and a source of energy in order to function

H ETEROTROPH – OBTAINS CARBON FROM OTHER ORGANISMS Photoheterotroph – uses light energy but gets carbon from other organism online.org/dictionary/Photoheterotroph Chemoheterotroph – obtains energy chemically and gets carbon from other organism online.org/dictionary/Chemoheterotroph

A UTOTROPH – O BTAINS CARBON DIRECTLY FROM CO2 ( CARBON DIOXIDE ) Photoautotoph – uses light as energy source and gets carbon from CO2, like a plant Chemoautotroph – uses chemicals as energy source and gets carbon from CO2 (methanogens) online.org/dictionary/Chemoautotroph
