Abstract
β‐Galactosidase (β‐gal) and 6‐phospho‐β‐galactosidase (P‐β‐gal) activities were measured in a total of 34 strains from Lactobacillus acidophilus, Lactobacillus crispatus, Lactobacillus amylovorus, Lactobacillus gasseri and Lactobacillus johnsonii. The Lact. gasseri strains have P‐β‐gal but little or no β‐gal activities. The strains from other species have β‐gal but only very little P‐β‐gal activities.
