Изобретение относитс к микробиологической промышленности.This invention relates to the microbiological industry.
Известна питательна среда дл культивировани Aspergillus foetidus - продуцента ферментов, содержаща пшеничные отруби, свекловичный жом и минеральные соли.A known nutrient medium for the cultivation of Aspergillus foetidus is an enzyme producer, containing wheat bran, beet pulp and mineral salts.
С целью интенсификации биосинтеза протеолитических ферментов, в частности кислой протеиназы, в предлагаемой среде пшеничные отруби и свекловичный жом содержатс в количествах соответственно равных, %: 87-74 и 10-20, из минеральных солей используют нитрат натри в количестве 3-6%.In order to intensify the biosynthesis of proteolytic enzymes, in particular acidic proteinase, wheat bran and beet pulp in the proposed medium are contained in amounts of, respectively,%: 87-74 and 10-20;
Суш,ность изобретени заключаетс в следуюш:ем .The dryness of the invention is as follows.
Выращивание плесневого гриба Aspergillus foetidus провод т на питательной среде, содержащей пшеничные отруби 87-74%, свекловичный жом 10-20% и нитратные соли щелочных металлов 3-6%, в течение 48 часGrowing mold fungus Aspergillus foetidus is carried out on a nutrient medium containing wheat bran 87-74%, beet pulp 10-20% and nitrate salts of alkali metals 3-6%, within 48 hours
при 32-36°С. Выросша культура гриба представл ет собой остатки питательной среды , проросшей мицелием.at 32-36 ° C. The grown mushroom culture is a remnant of a nutrient medium sprouted by mycelium.
Готовую культуру гриба измельчают и заливают водой в соотношении 1:2,5-1:3,5 к весу абс. сухой культуры. Экстракцию ведут в течение 40-60 мин, после чего массу отжимают до влажности 60-62%, фильтрат собирают и используют дл дальнейшего выделени ферментного препарата кислой протеиназы .The finished culture of the fungus is crushed and filled with water in a ratio of 1: 2.5-1: 3.5 to the weight of abs. dry culture. Extraction is carried out for 40-60 minutes, after which the mass is pressed to a moisture content of 60-62%, the filtrate is collected and used to further isolate the acidic proteinase enzyme preparation.
Выделение препарата провод т осаждением этиловым спиртом при концентрации в смеси 70-72%.Isolation of the drug is carried out by precipitation with ethyl alcohol at a concentration in the mixture of 70-72%.
Полученный осадок отдел ют центрифугированием при 3000 об/мин.The resulting precipitate was separated by centrifugation at 3000 rpm.
Ниже приведена таблица активности пектолитических и протеолитических ферментов, полученных с применением предложенной питательной среды и известных.Below is a table of the activity of pectolytic and proteolytic enzymes obtained using the proposed nutrient medium and known.
