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.
