Abstract
Abstract Novel, microbial α-galactosidase products which herein are designated a-galactomannangalactosidase, are able to split off D-galactopyranosyl groups from galactomannans without simultaneous degradation of the mannan backbone. The enzyme products can, for example, be prepared by Penicillium species. The novel enzyme products can be used even when the galactomannans are in a relatively high-concentration solution. Using the novel enzyme products, it is possible to prepare galactomannans having desired gelling capacities.
