Preliminary Investigation of Microbial Community in Wastewater and Surface Waters in Sri Lanka and the Philippines

In this study, the composition and richness of bacterial communities in treated and untreated wastewater from hospitals, commercial, and non-commercial fish farming sites, sewage effluents, and surface waters, which included seawater and fresh water in Sri Lanka and the Philippines, were investigate...
