Abstract

In this study, we investigated biofilm formation on galvanized steel coupons by anaerobic bacteria isolate including sulphate-reducing bacteria (SRB) isolated from cooling tower water in a lab-scaled experimental setup. The test coupons were exposed to the culture of anaerobic bacteria isolate during 744 hours. In the course of time, anaerobic bacteria isolate could form biofilm on galvanized steel coupons. According to the statistical analyses, there was no significant difference between sessile and planktonic SRB counts, while a positive correlation was found out between SRB counts (P

Özet

Çalışmada, laboratuvar ölçekli deney düzeneğinde, soğutma kule suyundan izole edilen sülfat indirgeyen bakteri (SRB) içeren anaerobik bakteri izolatının galvanizli çelik üzerinde biyofilm oluşturma yeteneği araştırılmıştır. Test kuponları 744 saat boyunca anaerobik bakteri izolatının içinde bırakılmıştır. SRB içeren anaerobik izolatının zaman içerisinde galvanizli çelik kuponlar üzerinde biyofilm oluşturabildiği saptanmıştır. İstatistiksel analizlere göre, sesil ve planktonik SRB sayılarının ortalamaları arasında anlamlı bir farkın olmadığı, bununla birlikte SRB sayıları arasında aynı yönde anlamlı bir ilişkinin olduğu tespit edilmiştir (P < 0.01). Test sistemindeki bakteri izolatının hücredışı karbonhidratı kullandığı belirlenmiştir
