Selection and properties of Streptococcus thermophilus mutants deficient in urease.

Journal of dairy science - 1 Jun 2004

Monnet C, Pernoud S, Sepulchre A, Fremaux C, Corrieu G

Abstract excerpt

Natural variations of the urea content of milk have a detrimental effect on the regularity of acidification by Streptococcus thermophilus strains used in dairy processes. The aim of the present study was to select urease-deficient mutants of S. thermophilus and to investigate their properties. Using an improved screening medium on agar plates, mutants were selected from 4 different parent strains after mutagen...
