where CelluloseS (g) is the amount of cellulose in the substrate, CelluloseR
is the amount of cellulose in the residual solid after SSF (g),
determined after strong acid hydrolysis, and GlucoseR is the unfermented
glucose in the liquor after SSF, determined directly by HPLC
(Varga et al., 2004). The factor of 0.568 is the theoretical conversion
factor for ethanol from cellulose by S. cerevisiae
