Effects of Hypocrellin Production of Amylase Addition under Solid State Fermentation by Shiraia bambusicola

Abstract:

The research investigated the effects of hypocrellin production of agitation and amylase addition under solid state fermentation by Shiraia bambusicola. The optimized experimental conditions were as follows：the first agitation on the third day，intermittent agitation every 36 hours，bacterial mesophilic α-amylase（2.85 U/g） added at the start time and glucoamylase（29.78 U/g） added on the third day. After optimization，hypocrellin production reached 60.74 mg/g within 13 d，which was 3.66 folds than previous study. This is the first report that amylase addition is used in SSF and it would have significant effect on hypocrellin production.
