COMPLEX HYDROLYTIC ENZYMES PRODUCER FOR MICROMYCETE ASPERGILLUS FOETIDUS
As a result of the selection with the use of induced multi-stage mutagenesis, a new strain of Aspergillus foetidus was obtained. A. foetidus is a producer of highly active hydrolytic enzymes (pectinase, glucanase, xylanase, cellulase, chitinase and protease) effective in processing agroindustry. The optimum conditions were chosen for strain generation: broth based on malt sprouts, wheat bran and (NH4)2SO4 with the initial value of 5.5 pH, temperature 28-30 °C and cultivation duration 48-120 h. As a result of cultivation of the mutant strain A. foetidus, freeze dried enzyme preparation Glucanofoetidin was obtained and studied for the enzymatic ability of the enzymic complex and physical-chemical preparation properties. It is found that the enzyme preparation Glucanofoetidin is multi-component with high catalytic activity of enzymes (glucanase - 1125, polygalacturonase - 2000 u/g). The use of the preparation will significantly increase the efficiency of plant and microbial raw material processing.
