Freeze-dried bacteria strengthens soil, fixes cracks, boosts construction
The freeze-dried bacteria demonstrated the ability to strengthen soil within 24 hours in field tests.
MMaking and fixing cement could become much easier with the help of bacteria that produce biocement. However, keeping these bacteria alive at construction sites has been difficult.
Now, scientists have found a way to freeze-dry the bacteria so they can be stored as a powder.
This could allow construction workers to mix them with other materials when needed—just like using instant coffee. The research could help with making tiles, repairing oil wells, and strengthening the ground for makeshift roads and camps.
