Summary:
The nature, activity and metabolism of microbes that inhabit the deep subsurface environment are a matter of ongoing debate. Primarily limited by temperature , little is known about secondary factors that restrict or enhance microbial activity or about the extent of a habitable environment deep below the surface. In particular, the degraders of chemically inert organic substrates remain elusive.

The nature, activity and metabolism of microbes that inhabit the deep subsurface environment are a matter of ongoing debate.

Primarily limited by temperature , little is known about secondary factors that restrict or enhance microbial activity or about the extent of a habitable environment deep below the surface. In particular, the degraders of chemically inert organic substrates remain elusive.

Petroleum reservoirs can be regarded as natural bioreactors and are ideally suited for the study of microbial metabolism in the deep subsurface.

Researchers have now analysed a series of oil samples that were biodegraded to different degrees. They found fatty acids after hydrolysis of purified crude oil fractions, indicating the presence of intact phospholipids and suggesting that indigenous bacteria inhabit petroleum reservoirs in sediment depths of up to 2,000 m.

A major change in bacterial community structure occurs after the removal of n-alkanes, indicating that more than one consortium is responsible for petroleum degradation . These results suggest that further study of petroleum fluids will help understand bacterial metabolism and diversity in this habitat of the deep subsurface.
