    <td colspan="3" align="left">Pollution is a major problem in our society, especially on cities, where   the high population density and pollution are congregated. Actually   there are some methods for pollutants detection in soil and water, but   few methods are available for detecting air pollutants, this type of   contamination may seem less obvious, but is alike dangerous for human   health and life quality. One of the most released pollutants to the   atmosphere is carbon dioxide CO<sub>2</sub>, direct   product of fossil fuel combustion and mostly responsible for climate   change. Our goal is to generate a biobrick whose function is to   indirectly detect atmospheric CO<sub>2</sub> by   detecting the compounds formed by the dissociation of  CO<sub>2</sub> in water product of the enzyme carbonic anhydrase.  The enzyme carbonic anhydrease's reaction, in his reduced form is: </td>

Also, an association of the HCO<sup>-</sup><sub>3</sub> ratio and the signaling pathway of adenilate cyclase has been seen. The utilization of these genes with reporter proteins can be used to indirectly calculate the concentration of environmental CO<sub>2</sub> as a function of the partial pressure and the speed is assimilated by the liquid medium, the fastest it gets to the saturation point 5% the higher is the CO<sub>2</sub> concentration. This is added to the effort of design a possible system for in situ air bioremediation applicable to cities and a campaign of awareness for the population about biology methods, specifically synthetic biology that can improve the quality of the environment and our lives without leaving aside the importance of conservation and environmental care. Our human practices are focus on that direction with workshops, scientific diffusion talks and the possible development of mobile applications that promotes consciousness about the importance of the environmental care and its impact on synthetic biology. </td>
