Biofilm growth at pH 11?

Fri Aug 22 16:22:52 EST 1997

I have a few questions that someone here might be able to answer.

Would biofilm grow at pH 11 or higher in a tank of 40% EDTA?

Has flocculation been observed with biofilms? For example, could it
travel through a 30 micron filter and then precipitate/flocculate?

Has anyone seen inclusion of magnetic iron/iron oxide in biofilms?

Thanks very much for any help you can give me.
