In this study, the formation of biofilms in dairy industry was investigated. Biofilm samples were collected from the equipments of various dairy plants in Burdur and Isparta cities in Turkey. A biofilm layer was formed with isolated strains under laboratory conditions, and several disinfection procedures were applied to these biofilms. To remove the biofilms formed on stainless steel plates, six different disinfectants were used at different concentrations and impact times. Following microbial loads were found in samples collected from biofilms; total mesophilic aerob bacteria

Süt Sanayisinde Biyofilm Oluşturan Mikroorganizmalar ve Biyofilm Oluşumunun Önlenmesi

Öz

Bu çalışmada, süt sanayisinde biyofilm oluşumu üzerinde çalışılmıştır. Bu amaçla Burdur ve Isparta’da süt işletmelerinden biyofilm örnekleri toplanarak, mikroorganizma profili belirlenmiştir. İşletmeden alınan örneklerden izole edilen izolatlarla laboratuar koşullarında biyofilm oluşturulmuş ve oluşan biyofilm üzerine çeşitli ticari dezenfektanlar kullanılmıştır. Laboratuar koşullarında paslanmaz çelik yüzeyde oluşturulan biyofilmin temizlenmesi için uygun olan zaman ve konsantrasyonu tespit etmek için farklı konsantrasyonlarda ve farklı sürelerde işlem uygulanmıştır. Alınan örneklerden izole edilen mikroorganizma grupları şu şekilde bulunmuştur: Toplam mezofilik aerob bakteri grubu
