where rGg is the molecular weight ratio of a cellulose monomer to glucose (162,16/180,18), fG is glucose mass
fraction into the slurry at the end of hydrolysis, rGcb is the molecular weight ratio of two glucan monomers to
cellobiose (324.32/342.34), fcb is cellobiose mass fraction, WISDM is the initial dry mass fraction of insoluble solids
insert into the bioreactor, %g is percentage of glucan in WISDM.
