Bu çalışmada, Kahramanmaraş ve çevresindeki içme/kullanma suları ile çevresel (nehir, göl) gibi suların mikrobiyolojik kalitesi araştırıldı. Bu araştırmada, çeşitli su örneklerinden membran filtrasyon yöntemi ile bakteriler izole edildi. Bu amaçla, su kaynaklarından 6 ay süresince toplanan 67 adet su numunesi çalışmaya alındı. Numuneler, 0.45μm porlu selüloz membran filtrelerden süzüldükten sonra filtreler Endo-NKS ve Standart TTC-NKS besiyerlerine yerleştirildi. Daha sonra her besiyeri 37 ºC’de 24 saat inkübe edildi. Besiyerlerinde üreyen bakteri kolonileri biyokimyasal yöntemlerle identifiye edildi. Sonuçta, 67 adet su numunesinin 53’ünde (%79) Escherichia coli ve diğer bakteriler izole edildi. İçme ve kullanma sularındaki Escherichia coli varlığı fekal bir kontaminasyonu gösterdiğinden, bu durumun su kaynaklı infeksiyonlara yol açabileceği düşünülmektedir.

Anahtar sözcükler: Membran filtrasyon yöntemi, içme ve kullanma suyu, çevresel sular, bakteriler

 

Detection of Microbial Quality of Drinking, Using and Environmental Waters in Kahramanmaraş City by Membrane Filtration System

 

ABSTRACT: In this study, the microbiological quality of drinking/using water and environmental (river, lake) waters was investigated in Kahramanmaraş area. In this investigation, bacteria were isolated by using membrane filtration methods from some water samples. For this purpose, 67 water samples TTC were collected and analyzed over course of 6 months. The samples were filtered through 0.45μm pore size cellulose membrane filter. After filtration, filters was placed on the Endo-NKS and Standart TTC-NKS medium and incubated for 24h at 37 ºC. Bacteria colonies on the medium were identified by biochemical methods. In conclusion, Escherichia coli and different bacteria were isolated in 53 (79 %) of 67 water samples. The presence of Escherichia coli in the water samples exhibited existence of fecal contamination in the drinking/using water, which is thought to cause water origin infections.

Key words: Membrane filtration method, drinking and using water, environmental waters, bacteria
