Galactokinase activity in Streptococcus thermophilus
Applied and Environmental Microbiology, 1985ATP-dependent phosphorylation of [14C]galactose by 11 strains of Streptococcus thermophilus indicated that these organisms possessed the Leloir enzyme, galactokinase (galK). Activities were 10 times higher in fully induced, galactose-fermenting (Gal+) strains than in galactose-nonfermenting (Gal-) strains.

Urease production by Streptococcus thermophilus
Food Microbiology, 2008In order to identify potential alternative sources of urease for the removal of urea from alcoholic beverages, 205 strains of lactic acid bacteria belonging to 27 different species were screened for urease production. Only Streptococcus thermophilus produced urease. Cell permeabilization with toluene allowed to increase activity significantly.

Susceptibility of Streptococcus thermophilus to antibiotics
Antonie van Leeuwenhoek, 2006A total of 74 Streptococcus thermophilus isolates collected between 1948 and 2005 from different environments were investigated to assess erythromycin, clindamycin, streptomycin, gentamicin, tetracycline and ampicillin susceptibility by means of microdilution, Etest and disk diffusion methods. For this purpose a new S.

Urease biogenesis in Streptococcus thermophilus
Research in Microbiology, 2005Urease biogenesis was monitored in the lactic acid bacterium Streptococcus thermophilus during the growth cycle using in-gel detection and a phenol-hypochloride assay. Zymogram analysis, performed in a non-denaturing polyacrylamide gel, enabled visualization of a complex profile of bands whose number and intensity were dependent on the growth phase and

Streptococcus thermophilus bacteriophages
International Dairy Journal, 2010At least 345 bacteriophages infecting Streptococcus thermophilus starter cultures have been isolated; general characteristics include high thermal resistance, short latent periods and large burst size. Phages with such characteristics are primed to thrive in the cheese making environment, lysing bacterial cultures and generating low-quality fermented ...

Genetic transformation of Streptococcus thermophilus by electroporation
Biochimie, 1988A rapid and convenient electroporation procedure was developed for the genetic transformation of intact cells of Streptococcus thermophilus with various species of plasmid DNA. Transformation frequency was influenced by the capacitance and voltage selected for electric pulsing, the pH and composition of the electroporation medium and the molecular mass

Efficient insertional mutagenesis in Streptococcus thermophilus
Gene, 2000Bacteria have always been considered ideal organisms for genetic analysis. While this is true for some model organisms, like Escherichia coli, Bacillus subtilis and, more recently, Lactococcus lactis, genetic analysis of other organisms is often prevented by lack of valuable tools, like vectors, transposons and methods for transformation, gene ...
