Annotation and De Novo Sequence Characterization of Extracellular β-Fructofuranosidase from Penicillium chrysogenum Strain HKF42

The genome of a fungal strain Penicillium chrysogenum strain HKF42, which can grow on 20% sucrose has been annotated for 7595 protein coding sequences. On mining of CAZymes, we could annotate a β-fructofuranosidase gene responsible for fructo-oligosaccharides (FOS) synthesis which is a known prebiotic. The enzyme activity was demonstrated and validated with the generation of FOS as kestose and nystose.
