AB  - Urea is an abundant nitrogen-containing compound found in urine of mammals and 
      widely used in fertilizers. This compound is part of the nitrogen biogeochemical 
      cycle and is easily biodegraded by ureolytic microorganisms that have the urease 
      enzyme. Previous studies, with ureolytic isolates, have shown that some ureolytic 
      microorganisms are able to sequester CO(2) through a process called 
      microbially-induced calcium carbonate precipitation. The present study 
      investigates 15 ureolytic consortia obtained from the "Pamukkale travertines" and 
      the "Cave Without A Name" using different growth media to identify the possible 
      bacterial genera responsible for CO(2) sequestration through the 
      microbially-induced calcite precipitation (MICP). The community structure and 
      diversity were determined by deep-sequencing. The results showed that all 
      consortia presented varying CO(2) sequestration capabilities and MICP rates. The 
      CO(2) sequestration varied between 0 and 86.4%, and it depended largely on the 
      community structure, as well as on pH. Consortia with predominance of Comamonas, 
      Plesiomonas and Oxalobacter presented reduced CO(2) sequestration. On the other 
      hand, consortia dominated by Sporosarcina, Sphingobacterium, Stenotrophomonas, 
      Acinetobacter, and Elizabethkingia showed higher rates of CO(2) uptake in the 
      serum bottle headspace.
