Production of fructooligosaccharides by crude enzyme preparations of beta-fructofuranosidase from Aureobasidium pullulans.
Fructooligosaccharides (FOS) were produced from sucrose by using crude enzyme preparations of beta-fructofuranosidases (FFases) obtained from sucrose-cultured cells of Aureobasidium pullulans DSM 2404. When the preparation mainly consisted of FFase I, that has high transfructosylating activity, the FOS yield was 62%. When the reaction was carried out with additional commercial glucose isomerase (GI) at an activity ratio of FFase and GI of 1:2, the maximum FOS yield reached 69%. This value was higher than those obtained previously using other Aureobasidium spp. (53-59%).
