Bioconversion of paper sludge to biofuel by simultaneous saccharification and fermentation using a cellulase of paper sludge origin and thermotolerant Saccharomyces cerevisiaeTJ14

Table 3 Y_s estimated 64% based on experimental data; 192 g PSOM used

Factor	Estimated sugar amount (g)
Theoretical glucose needed	38.8 g/l/0.51 × 1.2 l = 91.3
RS at the end fermentation	11 g/l × 1.2 l = 14.4
Glucose for yeast maintenance	m^a (g/g cell/h) × 7.1 g/l × 72 h = 17.5
Total RS in hydrolysate	123
Estimated Y_s (%)	123/192 × 100 = 64.0
