| Question | Answer |
|---|---|
| what are the chemical requirements necessary for microbial growth | carob, oxygen, nitrogen, sulfur, phosphorus, trace elements, growth factors |
| categorize microbes based on their energy and carbon source | Autotrophs and Heterotrophs, chemotrophs, phototrophs |
| Autotrophs | those using inorganic carbon source |
| Heterotrophs | those catabolizing organic molecules |
| chemotrophs | acquire energy from redox reactions involving inorganic and organic chemicals |
| phototrophs | use light as their energy source |
| classify microbes into four groups on the basis of their preferred temperature range | psychrophiles: optimum below 15 C Mesophiles: grow best |
