Simultaneous saccharification and cofermentation SSCF

The methods for fermentation of cellulose ethanol include direct and indirect fermentation, mixed strain fermentation, SSF, simultaneous saccharification and cofermentation (SSCF), nonisothermal SSF, and immobilized cell fermentation.

Figure 2 An illustration of the various research activities underway to develop the next generation bioethanol plant. The 3 key areas of R D are in pretreatments, enzyme hydrolysis andfermentations. Significant efforts focus on process engineering cmd plant designs with the following at the core SHF -separate hydrolysis and fermentation, SSF - a simultaneous saccharification-fermentation, or SSCF - a simultaneous saccharification-cofermentation.

Cellulose hydrolysis and fermentation of sugar solution carried out in the same tank is referred to as SSF. Simultaneous saccharification of both cellulose (to glucose) and hemicellulose (to xylose and arabinose) and cofermentation of both glucose and xylose carried out by genetically engineered microbes that ferment xylose and glucose in the same broth is referred to as SSCF.
