| Abstract: | Uncontrolled and catastrophic releases of
petroleum pose ecologicaland environmental repercussions as a lot of hydrocarbon
components are toxic and persistent in terrestrial and aquatic environments.
Several physico-chemical methods of decontaminating the environment have been
established and employed. Biological degradation, a safe, effective and an
economic alternative method, is a process of decay initiated by biological
agents, specifically in this case by microorganisms. Bioremediation refers to
site restoration through the removal of organic contaminants by microorganisms.
Biodegradation of hydrocarbons is largely carried out by diverse bacterial
populations, which are ubiquitously distributed in the environment. The most
commonly reported genera of hydrocarbon-degraders include Pseudomonas,
Acinetobacter, Nocardia, Vibrio and Achromobacter. The factors, that
influence the rates of microbial degradation of hydrocarbons, include
temperature, pH, salinity, oxygen, nutrients, and physical and chemical composition
of petroleum. Due to the complexity of crude oil, biodegradation involves the
interaction of many different microbial species. It could be attributed to the
effects of synergistic interactions among members of the consortium. |
