Biocementation Column

Materials

  • 15 mL falcon tube
  • 20 g of Lunar/Martian regolith per tube
  • A peristaltic pump
  • Two feet of rubber tubing, epoxy glue, fabric matting
  • Heat Lamp
  • 30 mL of S. pasteurii culture (OD600 1.2)

Procedure

  • The columns were first prewet with 20 mL of sterile Bang media.
  • The bacteria culture was draw into the feed tube, and allowed to settle in the column overnight
  • Cementation solution (1.5 M equimolar urea and calcium chloride) was fed into the feed tube, which was then placed into a constant loop with the output tube
  • The column was heated for 5 days, and allowed to cycle.
