Relationship Between Exopolysaccharide Production and Phage Resistance in Lactococcus Lactis (Turkish with English Abstract)
Abstract
Seven of 90 strains of Lactococcus lactis, originated from Turkey, showed complete resistance against 25 lactic phages. Six strains of totally 7 were determined as exopolysaccharide producers. Capsular exopolysaccharides and exopolysaccharides which are loosely associated to the cell wall were identified for four and two strains, respectively. It is determined that phage resistance phenotypes are formed by inhibition of phage adsorption in all exopolysaccharide producer strains.

Abstract
Türkiye kökenli 90 Lactococcus lactis suşunun 25 laktik faja karşı test edilmesi sonucu, 7 adet susun tüm fajlara karşı tam direnç gösterdiği belirlendi. Yedi suştan altı adedi ekzopolisakkarit üretme yeteneğinde bulundu. Bu suşlardan 4 adedinin kapsüler, 2 adedinin ise hücre duvarı ile gevşek ilişkili ekzopolisakkaritler ürettiği saptandı. Tüm ekzopotisakkarit üreten L. lactis suşlarında, faj dirençlilik fenotipinin faj adsorbsiyonunun engellenmesi suretiyle oluşturulduğu tespit edildi.
