Project Overview
The British Columbia mining industry is a vital economic generator for the province, estimating at $8.5 billion in revenue per year. It touches the lives of every British Columbian, from creating 30,000 direct jobs to generating revenues used by the government to fund education, health care, transportation projects, and other public services. As the demand for B.C minerals grow in the global markets, so does the industry. However, current mining practices are expensive, chemically intensive, and energetically demanding. These practices lead to esthetic challenges (open pits) and the generation of tailings ponds that are difficult to monitor and control in the future. With environmental regulations becoming ever more stringent, these common practices are coming under greater scrutiny. The BC mining association and its members have taken a proactive stance; they were the first province to adopt a “sustainable mining initiative” aimed towards increasing efficiency while reducing environmental impact through innovative methods. In alignment with these goals, the 2014 UBC iGEM project seeks to improve the efficiency of mineral separation from impurities via a bacterium expressing two types of peptides on its surface. The first set are known to bind specifically to chalcopyrite (CuFeS2) and sphalerite (ZnS), minerals commonly found in natural ores. The second set aggregates the bacteria to facilitate extraction.
