− | <h2> | + | <h2>To determine what type of product could make the biggest impact, CU Boulder iGEM analyzed the environmental risks of fracking and the shortcomings of current solution methods. The result was a design that uses E. coli to test trace fracking fluid contaminants that anybody can use easily and effectively. CU Boulder iGEM interviewed petroleum engineer David Meyer for insight into the history of fracking.</h2> |
− | <p> | + | <p>Despite fracking being a relatively recent topic among environmental discussions, the technology to drill vertical hydraulic fracturing wells has been around and used since 1940s. It wasn’t until the 1980s when George P. Mitchell, a petroleum engineer from Texas, invented the horizontal drilling process. Soon, no natural gas companies could survive unless the adapted the technique themselves. By the 1990s, more than 80% of natural gas in the United States was extracted with fracking, and environmentalists began to fear some of the unintended consequences of the practice. Chemistry and law quickly stepped in to evaluate remediation options, all of which has led to the creation of CU Boulder iGEM team’s device.</p> |

<p>The first description of a whole-cell biosensor with environmental applications was described by researchers at the Swiss Federal Institute for Environmental Science and Technology. They engineered Pseudomonas putida bacteria to luminesce proportionately to aqueous naphthalene concentrations. However, these bacteria had complex biochemical pathways that were not well enough understood to be easily adjusted and refined. Furthermore, the cells were not sensitive enough to report the dilute naphthalene concentrations that fracking companies may be interested in reporting.</p> | <p>The first description of a whole-cell biosensor with environmental applications was described by researchers at the Swiss Federal Institute for Environmental Science and Technology.

− | <p> | + | <p>The Naphthalene Recorder project by CU Boulder iGEM incorporates the whole-cell concept for simplicity of processing and production and extends OptiEnz concept of measuring untreated samples from bodies of water by introducing a stake that can maintain homeostatic conditions wherever it’s placed. The concept of a low-maintenance network with contaminant “memory” extends the concept proposed for methane sensors, and its use can allow the public to run their own tests, avoiding lawsuits and not being strictly dependent upon the law requiring a company to run a test themselves.</p> |
