Molecular profiling of culturable bacteria from portable drinking water filtration systems and tap water in three cities of Metro Manila, Philippines

摘要: Many consumers drink filtered water from portable filtration system or directly tap water. However, microbial community composition in drinking systems has not yet been investigated. This study determined the molecular profile of culturable bacteria biofilms and three key cities Metro Manila, Philippines. A total 97 isolates were obtained using different growth media characterized based on 16S rRNA gene sequences. Most isolated biofilms, followed by least affiliated with Proteobacteria (α, β, γ), Actinobacteria, Firmicutes Bacteriodetes; some had no matches low affiliations data bank. associated that part normal flora. Some opportunistic bacterial pathogens, soil activated sludge bacteria. The presence may pose health risks when immunocompromised very percentage homology affiliates without bank suggesting identities novelty isolates. Further studies are needed for available market, quality status other areas functions is first report use potato dextrose agar isolation environment. It also profiling systems.
