FUNGAL STRAIN Aspergillus foetidus - PRODUCER OF COMPLEX OF PECTINASES, β-GLUCANASE, XYLANASE, CELLULASE, CHITINASE, MANNANASE AND PROTEASE FOR DESTRUCTION OF POLYMERS OF PLANT AND MICROBIAL RAW MATERIAL Russian patent published in 2015 - IPC C12N1/14 C12N9/24 C12N9/42 C12N9/62 C12R1/66 

FIELD: biotechnology.

SUBSTANCE: strain of micromycete Aspergillus foetidus 379-K-5-1 is proposed, producing a complex of pectinases, β-glucanase, xylanase, cellulase, chitinase, mannanase and protease for the destruction of polysaccharides of a plant and microbial material. The strain is deposited in the Departmental collection of useful microorganisms for agricultural purposes of the Russian Academy of Agricultural Science (RCAM) of the State Scientific Institution of the Russian National Research Institute for Agricultural Microbiology under the registration number of RCAM 01136. The advantage of the new strain is to obtain the more active complex of enzymes catalyzing the hydrolysis of polysaccharides, as well as endopolygalacturonase and pectinesterase. The strain Aspergillus foetidus RCAM 01136 is produced using efficient methods of selection and mutagenesis using UV irradiation and nitrosoguanidine from the known strain.

EFFECT: invention enables to expand the range of the enzymes obtained, used for the destruction of polysaccharides.
