AIMS The milk acidification rate of Streptococcus thermophilus strains can be affected by several factors, one of which is the hydrolysis of urea by the urease complex. To evaluate the technological suitability of S. thermophilus strains deprived of urease activity in milk fermentation, the genetic cluster related to urease enzymatic activity has been characterized in the type strain DSM 20167T. METHODS AND RESULTS Amplification of the urease genes of S. thermophilus DSM 20167T was developed… CONTINUE READING
