Exogenous sucrose stimulated the production of invertase by strains YF43 and JCM 1126 simultaneously. In a medium containing fructooligosaccharide as the sole carbon source, the cells of strain YF43 showed high invertase activity in spite of poor growth. The two invertases produced in the cells grown on sucrose and fructooligosaccharide were an identical β-fructofuranosidase, as judged from properties of partially purified enzymes. These observations indicated that strain YF43 is a mutant improved for permeation of sucrose and not derepressed for the synthesis of invertase.
