This study is concerned with the effect of different cultivation techniques on enzymes produc- tion from sugar beet pulp by strain Neurospora crassa isolated from the environment. Cultivation of selected producing microorganism was carried out under the same process conditions using five techniques. Bioprocess efficacy was estimated based on amylolytic, cellulolytic and xylanolytic activity of prepared enzymes mixtures. The obtained results indicate that the selection of cultivation technique had a statistically significant effect on the production of examined hydrolytic enzymes. It was confirmed that solid state cultivation with spontaneous aeration is the best cultivation tech- nique for the production of amylolytic, cellulolytic and xylanolytic enzymes from sugar beet pulp by Neurospora crassa. Submerged cultivation of producing strain with spontaneous aeration resulted in the lowest production of all investigated enzymes under applied experimental conditions. The ob- tained results are the basis for further research aimed to increase the enzymes yield and activity of their mixture.
