Toxins In Our Environment

During the production of oil, gas, and many other natural products there is the production of numerous toxic components. These have become a huge problem in our society resulting in land, water, and air contamination. These consist of a variety different types of compounds. Air contaminants consist of NO_x (nitrogen containing compounds) and SO_x (sulfur containing compounds) which contribute to a variety of environmental issues including green house gas accumulation and acid rain. Similarly water contaminants often consist of complex mixtures of compounds including highly toxic phenols and aromatic compounds, corrosive and additionally toxic carboxylic acid containing compounds, sulfur, and nitrogen containing compounds. These often have complicated structures and demonstrate acute toxicity to wild life. Classical examples of water contamination include tailing ponds produced from the oil extraction process. Finally, land areas can become contaminated as a result of these toxic compounds leaching into ground water sources, spills or accidental release of waste products into the environment, and other ways.

Synthetic Biology As A Platform For Remediation

Presently, there are a variety of solutions to removing these compounds from the environment. This has been facilitated by stricter regulations from government bodies as well as better chemical and physical techniques for reducing the release of these compounds. Toxins which are released into the environment can be removed using various chemical agents or by physically removing contaminated soil or water areas. However there is still no efficient, environmentally healthy mechanism for this to occur. What needs to occur in order to better remediate these toxin's from the environment? We require a method to be able to easily detect where toxins are and also have a system for removing them from the environment. Microorganisms in the environment have evolved to be able to do both of these functions, responding to compounds in their environment and transform them into other products. Therefore we can harness these abilities to apply synthetic biology to these problems. What if we could detect toxins in our environment using a synthetically engineered organism? What if we could use a second organism to take these compounds and not only degrade them but convert them into useful compounds like hydrocarbons!
