AB  - Cadmium (Cd) is a toxic heavy metal that causes serious health problems and is 
      present in agriculturally important soils in Colombia, such as the ones used for 
      cocoa farming. Recently, the use of ureolytic bacteria by the Microbiologically 
      Induced Carbonate Precipitation (MICP) activity has been proposed as an 
      alternative to mitigate the availability of Cd in contaminated soils. In this 
      study, 12 urease-positive bacteria able to grow in the presence of Cd(II) were 
      isolated and identified. Three were selected based on urease activity, 
      precipitates formation and growth, with two belonging to the genus Serratia 
      (codes 4.1a and 5b) and one to Acinetobacter (code 6a). These isolates exhibited 
      low urease activity levels (3.09, 1.34 and 0.31 mumol mL(-1) h(-1), respectively), 
      but could raise the pH to values close to 9.0 and to produce carbonate 
      precipitates. It was shown that the presence of Cd affects the growth of the 
      selected isolates. However, urease activity was not negatively influenced. In 
      addition, the three isolates were observed to efficiently remove Cd from 
      solution. The two Serratia isolates presented maximum removals of 99.70% and 
      99.62%, with initial 0.05 mM Cd(II) in the culture medium (supplemented with urea 
      and Ca(II)) at 30  degrees C and 144 h of incubation. For the Acinetobacter isolate, the 
      maximum removal was 91.23% at the same conditions. Thus, this study evidences the 
      potential use of these bacteria for bioremediation treatments in samples 
      contaminated with Cd, and it is one of the few reports that shows the high 
      cadmium removal capacity of bacteria from the genus Serratia. SUPPLEMENTARY
