Types of Bacteria
By:Ryan, Lauren, Amruta, and Gage
Heterotrophs
- Heterotrophs make their own food, unlike autotrophs
- The way the energy is captured is from nutrients in other organisms
- These bacteria life in a bunch of environments
- An example is Clostridium, which is diarrhea
Photoheterotrophs
- Photo heterotrophs use light energy to make energy
- They live where a bunch of light is available
- An example is Rhodobacter
Photoautotrophs
- energy from light
- turn carbon into carbon compounds
- Live in abundant light
- Example:anabaena
Chemoautotrophs
- Energy from chemicals
- Energy from chemical reactions in environment like ammonia and hydrogen sulfide
- Live in areas with a lot of chemicals, tend to be dark
Obligate Aerobes
- Obligate aerobes are bacteria that require oxygen for respiration.
- An example would be "Mycobacterium tuberculosis", a bacteria that causes tuberculosis (a lung disease)
- live in areas with abundant oxygen
Obligate Anaerobes
- Obligate anaerobes are bacteria that are killed by oxygen
- An example would be "Treponema pallidum", a bacteria that caused syphilis, a sexually transmitted disease
- live in areas with little oxygen
Facultative Anaerobes
- Use oxygen, but can live without it
- Produce energy through cellular respiration and/fermentation
- Can live in oxygenated areas, or areas with little to no oxygen
- Example: E. Coli-can live in sewage with oxygen or in the intestine without oxygen
