Nine bacterial strains growing on inulin as the sole carbon and energy source were isolated from soil samples by enrichment culture on a mineral medium. Four of the strains were thermophilic and belong to the genus Bacillus. The thermophilic strains synthesized a beta-fructosidase that was active on both inulin and sucrose. The presence of inulin in the culture medium is necessary for enzyme synthesis. Most of the activity on inulin was recovered in the culture medium, and the enzyme was synthesized during cell growth.
从土壤样品中通过在矿物培养基上进行富集培养,分离到九株以菊粉为唯一碳源和能源的细菌菌株。其中四株为嗜热菌,属于芽孢杆菌属。嗜热菌株合成了一种β-果聚糖酶,对菊粉和蔗糖均具有活性。培养基中存在菊粉是酶合成所必需的。大部分菊粉活性都存在于培养基中,并且该酶是在细胞生长过程中合成的。
