METHOD FOR TECHNOLOGICAL PREPARING FERMENTED SUGARS FROM LIGNOCELLULOSE MATERIAL Russian patent published in 2008 - IPC C12N1/14 C12P19/02 C12P19/04 C12N9/42 

FIELD: biotechnology, microbiology.

SUBSTANCE: invention relates to a method for technological processing of lignocellulose materials. Method involves treatment of raw with enzyme preparation. As enzyme preparation method involves using a preparation obtained by culturing the strain Penicillium funiculosum S-2006 in medium containing the following components, g/l: cellulose, 50-60; glucose, 10-30; KH₂PO₄, 8-12; (NH₄)₂SO₄, 3-7; MgSO₄ x 7H₂O, 0.2-0.4; CaCl₂ x 2H₂O, 0.2-0.4, and the process is carried out at temperature 26-30^°C at the constant pH range 4.5-5.5. Treatment is carried out at intense stirring at temperature 45-55^°C in weakly acid medium. The amount of enzyme preparation is selected by so manner to provides activity by filter paper 9-11 U per 1 g of dry substrate. Method provides the high yield of fermented sugars.

EFFECT: improved preparing method.
