FC/FS values for municipal sewage were significantly higher than those values of the effluent from piggery wastewater. Enterococcus ratio, the ratio of (Enterococcus durans + E. hirae) to (Enterococcus faecalis + E. faecium). of human-sourced wastewater (0.90) was much lower than for pig-sourced wastewater (5.55). When FC/FS and enterococcus ratio were applied to a contaminated river study, both were corresponded well with the population density distribution of humans and pigs. FC/FS and enterococcus ratio are feasible microbial indicators for human- and pig-sourced wastewater pollution identification in field study. |
