Document Summary
Microbial nutrition for growth, all microbes require. C, o, h, n, s, p used to produce lipids, proteins, nucleic acids. K+, ca2+, mg2+, fe2+, fe3+ - cations, variety of functions. Heterotrophs glucose (c6o6h11), fats, proteins (organic materials) Autotrophs co2, no h (must get elsewhere), fix co2 into organic materials (reduce, make covalent bonds) Trace elements: required by organisms in small amounts, so small they can be acquired from water, media, etc. Light energy used to fix co2 into organics. No2 + o2 no3 produces energy. Note: chemo means gains energy from chemicals, either organic or inorganic. Autotrophs use co2 as sole source of c. Must use light or oxidation of inorganic molecules to obtain energy. Must get h/e- from inorganic molecules, e. g. h2o, h2, nh4. Heterotrophs use preformed organic molecules (usually from other organisms) as c source. Use organic molecules as h/e- source organotroph. Can use oxidation of organic molecules or light for energy.
