Abstract

Çalışma kapsamında
iki farklı atık su arıtma tesisinin çeşitli ünitelerinden örnek alınmış ve bu
örneklerin pH ve element içerikleri belirlenmiştir. Özellikleri belirlenen
örneklerden fenollü besiyerine inokülasyon yapılmış ve 19 izolat elde
edilmiştir. Bu izole edilen 19 izolattan morfolojik olarak farklı olduğu
düşünülen 9 izolatın tanımlaması yapılmıştır. İzolatlar arasında yoğun olarak Pseudomonas türleri belirlenmiştir.
Tanımlanan bu 9 izolatın atık sulardaki arıtım potansiyellerini
değerlendirebilmek için antibiyotik duyarlılık testi gerçekleştirilmiştir.
Ayrıca izolatların amilaz ve proteaz enzim üretim aktiviteleri
değerlendirilmiştir. İzolatların ofloksasin, azitromisin ve streptomisine
duyarlı oldukları belirlenmiştir. Enzim üretim yetenekleri değerlendirildiğinde
ise yalnızca 2 izolat zayıf proteaz aktivitesi gösterirken izolatların çoğu
amilaz aktivitesi göstermiştir.

ENZYMATIC AND ANTIBIOTIC SUSCEPTIBILITY ACTIVITIES OF PHENOL DEGRADING BACTERIA ISOLATED FROM WASTE WATER

Abstract

In the scope of the study, samples were
taken from various units of two different wastewater treatment plants and pH
and element contents of these samples were determined. Samples were inoculated on phenolic media and totally 19
isolates were obtained. Of these 19 isolates,
9 of them thought to be morphologically different were identified. Pseudomonas species have been identified
dominantly among the isolates. An antibiotic susceptibility test was performed to evaluate the treatment
potential of these 9 isolates in the wastewater. In addition, amylase and protease enzyme production
activities of isolates were evaluated. It has been determined that isolates are susceptible to ofloxacin,
azithromycin and streptomycin. When enzyme production capabilities were evaluated, only 2 isolates showed
poor protease activity, while most isolates showed amylase activity.
