Use of Humicola grisea glucoamylase in an SSF process at neutral pH

Embodiments of the present disclosure relate to a process for producing downstream products, such as fermentable sugars and end products, from a starch substrate by saccharification and/or fermentation. The saccharification is effectively catalyzed by a glucoamylase at a pH in the range of 5.0 to 8....

Zusammenfassung:Embodiments of the present disclosure relate to a process for producing downstream products, such as fermentable sugars and end products, from a starch substrate by saccharification and/or fermentation. The saccharification is effectively catalyzed by a glucoamylase at a pH in the range of 5.0 to 8.0. At a pH of 6.0 or above, the glucoamylase possesses at least 50% activity relative to its maximum activity. The saccharification and fermentation may be performed as a simultaneous saccharification and fermentation (SSF) process.
