Abstract A Monilia sp. produced an inducible intracellular β‐ d ‐glucosidase (IG‐2) which is the nascent form of the extracellular enzyme (EG‐1) prior to its secretion into the extracellular medium. The other intracellular β‐ d ‐glucosidase (IG‐1) produced was a constitutive enzyme. Highest yields of the inducible β‐ d ‐glucosidase resulted when Monilia sp. was grown on insoluble cellulose. Cellobiose and d ‐glucose appeared to repress β‐ d ‐glucosidase formation at high substrate levels and synthesis occurred only once the levels of these sugars in the medium were nearly depleted.
