RESUMO

Thirty-two bacterial strains growing on inulin as the sole carbon and energy source were isolated from soil samples by enrichment culture on a mineral medium. Twenty of the strains were identified as Flavobacterium multivorum. All the bacteria contained a β-fructosidase that was active on both inulin and sucrose. The enzyme activity was cell bound and was produced at the end of the growth phase. These enzymes have potential uses in the preparation of fructose syrups from inulin and invert sugar from sucrose.
