Saturated fractions of oil and gas are readily biodegraded in the near-surface environment by a host of microbial communities; as biodegradation proceeds, other components of the oil can also be destroyed.<ref name=ch11r28>Palmer, S., 1991, [http://archives.datapages.com/data/specpubs/geochem1/data/a037/a037/0001/0000/0047.htm Effect of biodegradation and water washing on crude oil composition], in Merrill, R., K., ed., Source and Migration Processes and Evaluation Techniques: [http://store.aapg.org/detail.aspx?id=436 AAPG Treatise of Petroleum Geology—Handbook of Petroleum Geology No. 1], p. 47–54.</ref> These factors aid biodegradation:
