β-Fructofuranosidase and sucrose phosphorylase of rumen bacterium Pseudobutyrivibrio ruminis strain 3.

The subject of this study was the fructan and sucrose degrading enzymes of bacterium Pseudobutyrivibrio ruminis strain 3. It was stated that cell extract from bacteria growing on inulin contained β-fructofuranosidase (EC 3.2.

Treponema zioleckii sp. nov., a novel fructan-utilizing species of rumen treponemes.

During studies on fructan degradation in the rumen, a Treponema-like bacterium able to utilize Timothy grass fructan, commercial inulin and sucrose as the sole carbon source was recovered from sheep rumen. At least two different fructanolytic enzymes were identified in cell-free extracts of the isolated bacterium. Characterization of the strain by a polyphasic approach indicated that it can be regarded as a representative of a new bacterial species within the genus Treponema.
