This can be done in different ways from a variety of carbon sources such as:

Some bacteria can used 1,2-propanediol as a carbon source.

Cells need nutrients - a carbon source, along with other elements - as well.

This means that these substances present a potential carbon source for fungi.

They are chemoheterotrophs, using light for energy and methane as a carbon source.

Researchers have also suggested using biomass as a carbon source for fuel production.

The metal is first melted in contact with a carbon source.

In the presence of oil, they must not be preferentially utilized as a carbon source.

They are able to make their own food, and do not need a living energy or organic carbon source.

They tend to grow best with pentoses as a carbon source.
