Bacteria (both aerobic and anaerobic) are observed to constitute a bio-filter. Is there any associated communities helping bacteria?
Yes both bacteria and fungi and sometimes coupling of bacteria and fungi used. But it depends on the target compounds you want to remove from water (I guess you are interested in wastewater). Often I see volatile compound removal through fungi biofiler is effective or by coupling of bac-fungi.

Thanks
In every biofiler the microbiual populatiopn is mixed one. It doesn´t matter of the treated matrix is wastewater or biofilter. It is aldo very important if biofilter is aerobic or anaerobic. The mixed microbial population in an aerobic biofilter treating wastewater contains all microbes listed by Pierlorenzo and protozoa could be present, too.
Dear Shankhadeep Chakrabortty, what type of pollutant treatment are you interested? Does it sludge, industrial, mine, ...?
