Carbon Requirement of Microorganisms

Carbon Requirement of Microorganisms - The most oxidized form of carbon is CO2, Organisms which are photosynthetic reduce CO2 to organic cell constituents. Energy for this process is derived from light or the oxidation of reduced inorganic compounds such as H2S.

On the other hand, all non photosynthetic organisms obtain their carbon requirement mainly from organic nutrients which contain reduced carbon compounds.
These organic carbon compounds not only provide the carbon for synthesis but also meet the energy requirement by entering into energy yielding metabolic pathways and are eventually oxidized to CO2.

Some microorganisms have the ability to synthesize all their cellular components using a, single organic carbon source for example.
E. coli and many other bacteria can synthesise carbon skeletons with glucose as the starting material, while others in addition to needing one major carbon substrate, also need other complex carbon containing components, which, they cannot synthesize.

These are called the growth factors which include vitamins. Some organisms have the ability to utilize more than one carbon compounds and show a great degree of versatility, while others are specialized.
