Abstract

The microbiological quality of bottled natural spring and mineral water, purchased at different markets in Eskişehir (Turkey) markets, was investigated. Applying the membrane filtration method, the aliquots of water samples were analyzed for the presence and enumeration of total coliforms, Escherichia coli, Enterococcus spp., Aeromonas hydrophila. Aerobic bacteria were counted as Heterotrophic Bacteria Count (HPC) ml-1 by incubation at 22 and 37 oC. While Bacillus species in bottled mineral water samples have also been determined, any bacteria or contamination in bottled drinking water samples have not found.

Abstract

Eskişehir (Türkiye)’deki farklı marketlerden toplanmış olan şişelenmiş doğal ve mineral suların mikrobiyal kalitesi incelenmiştir. Membran filtrasyon tekniği uygulanarak su örneklerinin kalitesi; toplam koliform, Escherichia coli, Enterococcus spp., Aeromonas hydrophila’nın varlığı ve miktarı yönünden analiz edilmiştir. Aerobik bakteriler 22 ve 37 ºC’de inkübasyonu sonucunda ml’deki heterotrofik bakteri sayısı (HPC) olarak belirlenmiştir. Şişelenmiş mineral su örneklerinde Bacillus türleri belirlenirken, şişelenmiş içme suyu örneklerinde herhangi bir bakteri ya da kontaminasyon bulunmamıştır
