Biofilms present in the plant roots are believed to supply a more effective substrate for removal of bacteria through various methods such as mechanical filtration, sedimentation, adsorption, die-off, predation, and antibiotic excretion (Soto et al., 1999; Karathanasis et al., 2003) Removal (83%e94%) of pathogen especially coliform and enteric bacteria by surface flow constructed wetlands has been reported earlier (Perkins and Hunter, 2000) . Predation is another mechanism that plays an important role in the removal of bacteria, protozoan (oocysts), and fecal coliforms from wastewater in constructed wetlands (Mandi et al., 1993; Green et al., 1997) . High removal efficiency 2 to 4 log 10 (99% to 100%) of pathogens particularly bacteria, viruses, protozoa (cysts), and helminths (eggs) from wastewater has been noted in vegetated constructed wetlands. ./cache/cord-269607-xh1hu3k4.txt ./txt/cord-269607-xh1hu3k4.txt
