Cracks in your concrete? You need ‘BacillaFilla’


From the Press Release 12th of November 2010. Joint project instructor Dr Jennifer Hallinan explains:

“Around five per cent of all man-made carbon dioxide emissions are from the production of concrete, making it a significant contributor to global warming
A bacteria that can knit together cracks in concrete structures by producing a special ‘glue’ has been developed by a team of students at Newcastle University.

The genetically-modified microbe has been programmed to swim down fine cracks in the concrete. Once at the bottom it produces a mixture of calcium carbonate and a bacterial glue which combine with the filamentous bacterial cells to ‘knit’ the building back together.
