AB  - Copper contamination in watercourses is a recent issue in countries where mining 
      operations are prevalent. In this study, the application of copper precipitation 
      through microbe-induced carbonate precipitation (MICP) was analyzed using urea 
      hydrolysis by bacteria to evaluate precipitated copper carbonates. This article 
      demonstrates the application of a copper precipitation assay involving 
      Sporosarcina pasteurii (in 0.5 mM Cu(2+) and 333 mM urea) and analyzes the 
      resultant low removal (10%). The analysis indicates that the low removal was a 
      consequence of Cu(2+) complexation with the ammonia resulting from the hydrolysis 
      of urea. However, the results indicate that there should be a positive 
      correlation between the initial urea concentration and the bacterial tolerance to 
      copper. This identifies a challenge in the industrial application of the process, 
      wherein a minimum consumption of urea represents an economic advantage. 
      Therefore, it is necessary to design a sequential process that decouples 
      bacterial growth and copper precipitation, thereby decreasing the urea 
      requirement.
