- Physiological Adaptions for oxygen
-
must have superoxide dismutases
2O2 + 2H2 -> O2 + 2H2O2
2H2Os -> with catalase 2H2o + O2 - Obligate Aerobe
-
SOP +
Catalase +
Ex Psedomones Species - Facultative Anaerobe
-
SOP +
Catalase +
Ex: Salmanella and E. Coli - Aerotolerant Anaerobe
-
SOP +
Catalase -
Ex: Streptococcus Species - Obligate Anaerobe
-
SOP -
Catalase -
Ex: Clastridium - Microaerophile
-
SOP +
Catalase +/- low levels
Ex: Heliocobacter sp - High pressure tolerant(Barotolerant)
- -260atm Barophiles found in the bottom of ocean. Called "Black Smokers"
- What has a very low organic carbon
- Barotolerant, Thermotolerant, Chemolithotrophs
- What does radiation do?
- Interferes with DNA structure. Thymine dimerization. Increases mutations
- What are the physiological adaptions for radiation?
- UV light- induciable DNA repair enzyme system.
- Electromagnetic Radiation
- Ionizing radiation-> increases formation of ROS(reactive oxygen species)
- Solar energy(phototrophs) and inorganic materials(Chemolithotrophs)go to ________ and that goes to ______ to use for growth
-
Reduced organic materials
Heterotrophs
