Soil bacteria - (Oct/20/2011 )

does anyone know how long it roughly would take to establish a biofilm on a surface if you placed it in the ground?

It will depend largely on humidity/moisture content of the soil - if it is dry, it could take a very long time. Under ideal conditions, I would have thought a week would be OK

Note: I'm not a microbiologist, but do know a bit of microbial ecology.

thanks,I want to basically plant electrodes in the ground and grow biofilm on the (large) electrodes, soil is water logged..so conditions would be anaerobic which would slow down the growth...

It can be even faster then a week.

It all depends on so many parameters.. its hard to tell.
