Abstract
Bu çalışmada, mundtisin KS üreticisi Enterococcus mundtii YB6.30 suşunun
teknolojik özellikleri ve güvenlik değerlendirmesinin fenotipik ve genotipik
yöntemler ile araştırılması amaçlanmıştır. E.
mundtii YB6.30 suşunun de Man, Rogosa and Sharpe broth ortamında,
yapılandırılmış yağsız süt ortamına göre daha hızlı asit üretim özelliği
gösterdiği belirlenmiştir. E. mundtii
YB6.30 suşunun proteolitik aktivite gösterdiği ve nitratı redükte ettiği fakat
lipolitik aktivite göstermediği tespit edilmiştir. YB6.30 suşu denemelerde
kullanılan antibiyotiklerin tamamına duyarlı bulunmuştur. Fenotipik testler
sonucu YB6.30 suşunun hemolitik aktivite ve jelatinaz aktivitesi göstermediği
belirlenmiştir. Polimeraz zincir reaksiyonu (PZR) ile YB6.30 suşunun virülens
faktör içermediği tespit edilmiştir. YB6.30 suşu histidin, lisin ve ornitini
dekarboksile edemez iken, tirozinden tiramin ürettiği belirlenmiştir. PZR
denemeleri sonucu YB6.30 suşunda yalnız tirozin dekarboksilaz (tdc) geni varlığı tespit edilmiştir. Bu
çalışmanın sonuçları mundtisin KS üreticisi E.
mundtii YB6.30 suşunun gıda endüstrisinde starter kültür olarak
kullanımının güvenli olduğunu göstermiştir.

Abstract
In this study, investigation of
technological properties and safety evaluation of mundticin KS producer Enterococcus mundtii YB6.30 by
phenotypic and genotypic methods were aimed. E. mundtii YB6.30 strain has been determined to show a faster acid
production properties in de Man, Rogosa and Sharpe broth than reconstituted
skim milk. E. mundtii YB6.30 strain
showed proteolytic activity and reduced nitrate but not showed lipolytic
activity. The YB6.30 strain was found to be sensitive to all antibiotics used
in this study. As a result of phenotypic tests, YB6.30 strain did not show
hemolytic and gelatinase activities. The YB6.30 strain was not found to contain
virulence factor genes using polymerase chain reaction (PCR). The YB6.30 strain
was found to produce tyramine from tyrosine while it did not decarboxylate
histidine, lysine and ornithine. As a result of PCR experiment, only tyrosine
decarboxylase gene (tdc) was detected
in YB6.30 strain. The results of this study showed that mundticin KS producer E. mundtii YB6.30 strain was safe to use
as a starter culture in the food industry.
