Possible, perhaps.  But I would not necessarily recommend it because 1) it is a useful water quality indicator of warm blooded fecal pollution and 2) there are no obvious signs that their presence is serving as a potential phytoremediator of pollutants.  Are there signs that the presence of fecal coliform in warm blooded animals serving as a phytorramediator of pollutants for internal health of organisms?  Do fecal coliform have a symbiotic relationship or purpose of mutual benefit?  If fecal coliform is added to waters or certain circumstances, then its usefulness as an indicator may be lost, or at least reduced.  But if you have information that suggests fecal coliform is the best phytoremediator for certain instances, or that it serves a purpose of mutual benefit to life, it would be worth considering.

Hi, I  dont thing so.High concentation of coliform bacteria is an indicator of polluted water

Raw river water can be used as a source for fecal coliform bacteria

First just some spelling errors.  Phytoremediation and coliform is one word.  Using plants to treat water for microbial safety is not novel since wetlands have been around and has been used to treat wastewaters for as long as I can remember.  Fecal coliform are indicator organisms and indicate the presence of fecal material that may indicate the presence of human pathogens.  They are not pathogenic themselves with a few exceptions (e.g. E.coli 0157:H7).  So if the purpose of your study is to treat for indicator organisms then growing E coli K12 and spiking waters would be a reasonable approach.  If your purpose is to treat for the removal of human pathogens then using real stuff like sewage effluent would be more appropriate.  You can still use indicator organisms like fecal comforms or E. coli to assess treatability.  I wish that individuals with limited subject knowledge could refrain from making comments,  it is not productive or helpful.

Joice,

I assume that your'e interested in studying the effectiveness of plants in removing FC (and the pathogens that FC's are used to monitor). As Angus Chu has pointed out, there are published studies of wetland treatments for coliforms, but more work needs to be done. You may want to look at the book " Treatment Wetlands" by Robert H. Kadlec and Robert L. Knight, CRC Press, Lewis Publishers, NY. I hope this helps.

Joice,

I thought the attached paper would interest you.
