Enzymatic Activity Measurements in Streptococcus Thermophilus

This application note measures the b-galactosidase and lactate dehydrogenase activities in Streptococcus thermophilus cells to evaluate the effect of carbon dioxide availability on the homolactic fermentation process. Streptococcus thermophilus is a major component of dairy starter cultures used for the manufacture of yogurt and cheese. The Precellys® 24 allow for simple and efficient homogenizing of the sample for accurate and precise data.
