where 0.88 is the coefficient that results from the molecular
weight ratio of the polymer and the monomer pentose, 0.93
is the saccharification yield of xylane to xylose, C2 is the
determined reducing sugars concentration (g/L) from the
DNS method, C1 the glucose concentration (g/L) from
above, V the total volume of sugar solution (L), M the
dry weight of the algal biomass sample (g) and a the dilution
of the sample (if any).
