SELECTIVE DELIGNIFICATION OF THE <I>Pennisetum purpureum x Pennisetum typhoides</I> GRASS USING LIGNINOLYTIC BASIDIOMYCETES

Samples of Pennisetum purpureum x Pennisetum typhoides grass of 120 days are put under selective fermentation in solid state with two strains of basidiomycetes fungi Ganoderma ssp and Lentinus ssp, during seven weeks. The delignification characterization is made by Fourier Transform Infrared Spectro...
