[Augmentation of the biodisposition of simple sugars from sorghum biomass mediated with biotechnologic processes]

The results of the enzymatic hydrolysis of pectin, hemicellulose and cellulose in the biomass of sweet sorghum (Sorghum vulgare var. saccharatum, L.) are reported. Some commercial enzymatic preparations were used: Maxazym CL 2000 (with prevailing cellulase activity), Rapidase C 80 (with prevailing pectinase activity) Rohament PC (mainly with pectinase and cellulase activities) and Rohament O (mainly with pectinase and hemicellulase activities). The treatment with Rohament PC, Rohament O and Rapidase C 80 gives an increase of the glucose content higher than the effect induced by Maxazym CL 2000. On the other hand, the cellulase and pectinase combined treatment (Maxazym CL 2000 + Rapidase C 80 or Maxazym CL 2000 + Rohament O) shows a good synergistic effect in the degradation of the plant cell wall cellulosic material.
