product recovery. Integration of two or more
process steps is important for simplification of the process and
reduction of production cost. To this effect, simultaneous saccharification and fermentation (SSF) of the pretreated lignocellulosic
feedstock is considered to be an ideal integrated process for ethanol production. It offers distinct advantages over separate hydrolysis and fermentation (SHF) in the production of ethanol from
lignocellulosic feedstock.
