Bioremediation can be carried out by bacteria that are naturally present. In biostimulation, the population of these helpful bacteria can be increased by adding nutrients. [6] [15] Bacteria can in principle be used to degrade hydrocarbons. [16] [17] Specific to marine oil spills, nitrogen and phosphorus have been key nutrients in biodegradation ...
Treatments that use these breakdown processes most commonly use heat and chemicals to extend the efficacy. [22] Later, more biological systems are used for specific ecosystems that use specific mechanisms. [22] Phytoremediation is a process in which plants are used to sequester toxins and hydrocarbons into plant tissue from contaminated soils.
Microbial biodegradation is the use of bioremediation and biotransformation methods to harness the naturally occurring ability of microbial xenobiotic metabolism to degrade, transform or accumulate environmental pollutants, including hydrocarbons (e.g. oil), polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), heterocyclic compounds (such as pyridine or quinoline ...
Pseudomonas putida is a Gram-negative, rod-shaped, saprophytic soil bacterium. [1] It has a versatile metabolism and is amenable to genetic manipulation, making it a common organism used in research, bioremediation, and synthesis of chemicals and other compounds.
Biostimulation involves the modification of the environment to stimulate existing bacteria capable of bioremediation.This can be done by addition of various forms of rate limiting nutrients and electron acceptors, such as phosphorus, nitrogen, oxygen, or carbon (e.g. in the form of molasses).

Geobacter is a genus of bacteria. Geobacter species are anaerobic respiration bacterial species which have capabilities that make them useful in bioremediation. Geobacter was found to be the first organism with the ability to oxidize organic compounds and metals, including iron, radioactive metals, and petroleum compounds into environmentally benign carbon dioxide while using iron oxide or ...
Pseudomonas alcaligenes is a Gram-negative aerobic bacterium used for bioremediation purposes of oil pollution, pesticide substances, and certain chemical substances, as it can degrade polycyclic aromatic hydrocarbons. [1] It can be a human pathogen, but occurrences are very rare.
