Abstract excerpt
Lactobacillus plantarum ATCC 8014 grew poorly on raffinose agar plates, but large mutant colonies appeared in high frequency from a thin film of background growth. The alpha-galactosidase and beta-galactosidase activities of L. plantarum ATCC 8014 and a mutant strain were studied in static cultures and pH-controlled fermenter cultures. Both alpha-galactosidase and beta-galactosidase production were inducible in...
