Abstract

The biosolids from municipal wastewater treatment plant contains several enteric microbial pathogens, predominantly Salmonella check for this species in other resources and Escherichia check for this species in other resources species in the range of 15-18 x 104 CFU/g and 11-12 x 104 CFU/g respectively. The present study investigates the influence of earthworm, Lampito mauritii check for this species in other resources on enteric pathogen during vermicomposting of municipal sewage sludge. The Biosolids (B), Rice straw (R) and Cow dung(C) were used in this study. The BR (3:1) and BRC (3:1:1) combination proved to be best in the removal of enteric pathogens. Both these combinations reduced the bacterial pathogens like Salmonella and Escherichia species to nil during 60 days stabilization period of vermicomposting. The gut analysis also proved that Salmonella species ranging 15-17 x 103 CFU/g and Escherichia species ranging 10- 14 x 102 CFU/g were completely eliminated in the gut after 70 days of vermicomposting period. @JASEM
