biofilm predation question

We have done a lot of work at CAMR studying protozoan gazing of 
biofilms, utilising our episcopic DIC and Hoffman Modulation 
Contrast microscopes. Some of you might recall seeing our videos 
at meetings.
In our most recent paper on the topic, we published a paper with 
Ann Brown, Terry Beveridge and Barbara Sherriff to describe 
predation during iron precipitation - some protozoa seem to 
preferentially ingest iron-encrusted bacteria! The paper describes 
the techniques pretty well.
See: D.A. Brown et al., (1998). Evaluation of microscopic 
techniques to observe iron precipitation in a natural microbial 
biofilm. FEMS Microbiology Ecology 26, 297-310.
