Ethanol production from PS cellulose in SSF
process in 250 cm3 flasks. Saccharification was carried out
by cellulase powder from C8-8 origin, and fermentation
was started by inoculum of yeast after 1, 2, 3 and 4 days PS
saccharification. Symbols: inoculum time after 1
dayesaccharification (closed rhombuses); 2
daysesaccharification (closed squares); 3
daysesaccharification (closed triangles); and 4
daysesaccharification (closed circles). Open and closed
symbols denote concentrations of glucose released and
ethanol produced, respectively. Error bars denote standard
deviation of three repeated experiments.
