In our paper, the material from <em>Ch. linum</em> was treated by enzyme L Visocozyme and we found optimized hydrolysis conditions, vis. enzyme concentration: 0.85 ml/g (42.5 IU/g), time: 33 hours, temperature: 50<sup>o</sup>C, and pH: 5.2. The hydrolysis results of <em>Ch. linum</em> were: 50.3 g/l sugar solution which were fermented with Red Ethanol yeast under the following conditions pH: 4.5, temperature: 27<sup>o</sup>C, rotation rates; 50 rpm, CFU yeast: 10<sup>9</sup>/l, and fermentation time: 108 hours. Ethanol product of fermentation process was 14.4 g/l.</p><p> </p> ER -
