Experiments

1. Movement into cracks
2. Speed of swimming in a particular direction

Parameters

1. Speed of swimming in a particular direction (wt)
2. Quantities of glue, s.s, CaCO3, cell density
3. Strength (tensile) of bonding agents, filamentous cells

 ???

1. Grown in fermenter, rich medium
   • Rods
2. Sporulation medium
   • spores
3. Spray canister
   • spores
4. Sprayed on concrete surface
   • germinate -> rods
5. In crack
   • rods
6. End of crack
   • Produce glue/CaCO3/silk/filaments
   • Produce signal peptides
