Inducible synthesis of β-galactosidase inKluyveromyces fragilis

  • Č. Novotný

Lactose,d-galactose, andl-arabinose induce the synthesis of β-galactosidase inKluyveromyces fragilis. Lactose is the best inducer with a maximum effect at 1.4 mm. The induced synthesis of the enzyme in glycerol grown stationary phase cells is triggered within 30 min of inducer addition, the full induction being achieved within subsequent 30–40 min.
