Description

ШТАММ ПЛЕСНЕВОГО ГРИБА ASPERGILLUS CLAVATUS 2286/5Strain of the fungus ASPERGILLUS CLAVATUS 2286/5

Известны различные штаммы плесневых грибов Aspergillus clavatus, обладающие способностью продуцировать фермент рибонуклеодеполимеразу .There are various strains of mold fungi Aspergillus clavatus, which have the ability to produce the enzyme ribonucleopolymerase.

Предлагаемый штамм Aspergillus clavatus 2286/5 отличаетс  высокой ферментативной активностью при глубинном культивировании на среде, содержаш;ей соевую муку, пептон и глюкозу в качестве источника органических веш;еств, а также минеральные соли. Этот штамм выделен из почвы (супесчаной) Белгородской области Борисоглебского района.The proposed strain Aspergillus clavatus 2286/5 is characterized by high enzymatic activity during deep cultivation on the medium containing soy flour, peptone and glucose as a source of organic matter, as well as mineral salts. This strain was isolated from the soil (sandy) Belgorod region Borisoglebsky district.

Он характеризуетс  следуюш;ими признаками .It is characterized by the following.

При выращивании на агаре Чапека при температуре 22-24° С на .10-12 суток диаметр колонии увеличиваетс  до 4,5 см. Вначале колонии имеют голубовато-зеленую окраску , котора  затем становитс  тускло-сизозеленой . Высота конидиеносцев до 1 мм, толщина 35 мк, размер вздутий 140-190X64 мк. Размер головок 400-700 мк; боковых стеригм 7-9x2,5 мк, верхних 9-11X2,5 мк; конидий 4,5-5,0X3,0-3,5 мк.When grown on Chapek agar at a temperature of 22-24 ° C for 10–12 days, the diameter of the colony increases to 4.5 cm. At the beginning, the colonies have a bluish-green color, which then becomes dull green. Height of conidiophores is up to 1 mm, thickness is 35 microns, size of bulges is 140-190X64 microns. Head size 400-700 microns; lateral sterigm 7-9x2.5 microns, upper 9-11X2.5 microns; Conidium 4.5-5.0X3.0-3.5 microns.

При глубинном выращивании на среде, содержащей 5,0э/о глюкозы, 1,0% пептона, 0,5% соевой муки, 0,050/0 MgSO4-7H20; 0,01% СаС12-2П2О, 0, KNOg, при температуре плюс 25±1°С мицелий представл ет собой бледно-желтую равномерную грибницу, состо щую из длинных разветвленных гиф, постепенно переход щих из одной фазы развити  в другую.When deep growing on a medium containing 5.0 e / o glucose, 1.0% peptone, 0.5% soy flour, 0.050 / 0 MgSO4-7H20; 0.01% Cac12-2P2O, 0, KNOg, at a temperature of plus 25 ± 1 ° C, the mycelium is a pale yellow uniform mycelium consisting of long branched hyphae gradually passing from one phase of development to another.

Наибольша  активность рибонуклеодеполимеразы в культуральной жидкости имеет место у трех и п ти суточных культур. Максимальна  активность внутриклеточного фермента наблюдаетс  у трех суточных культур.The highest activity of ribonucleopolymerase in the culture fluid occurs in three and five daily cultures. The maximum activity of the intracellular enzyme is observed in three daily cultures.

Суммарна  активность культуральной жидкости в 3-10 раз больше суммарной активности мицели .The total activity of the culture fluid is 3-10 times greater than the total activity of the mycelium.

При действии культуральной жидкости на рибонуклеиновую кислоту в качестве продуктов гидролиза обнаружены и идентифицированы аденилова , гуанилова , уридилова  и цитидилова  кислоты. Высока  продуктивность штамма не измен етс  при длительном хранении культуры на агаре Чапека при комнатной температуре и при пересевах.Under the action of the culture fluid on ribonucleic acid, adenylic, guanylic, uridicic and cytidicic acids were detected and identified as hydrolysis products. The high productivity of the strain does not change during long-term storage of the culture on Czapek agar at room temperature and during subcultures.

Предмет изобретени Subject invention

Штамм плесневого гриба Aspergillus clavatus 2286/5. Толщина конидиеносцев до 35 мк, высота до 1 мм, размер вздутий 140-190Х Х64 мк. Размер боковых стеригм 1-9X2,5 лк, верхних 9-11X2,5 мк, конидий 4,5-5,0X3,0- -3,5 мк, головок 400-700 мк. 3 колонии достигают в диаметре 4,5 см. Окраска колоний измен етс  от голубовато-зеленой до тускло-сизо-зеленой. Синтетическа  среда, (глюкоза, пептон , соева  мука и MgSO4-7H2O, CaCl2-2H20,5 KNOs). Мицелий желтоватый, разветвленные гифы длиной 450 ж/с. Диаметр гиф, равный в 4 первые сутки роста 5,0-7,5 мк, через 72 часа роста увеличиваетс  до 12 мк. Ферментативные свойства. При глубинном росте выдел ет фермент, деполимеризующий рибонуклеиновую кислоту с образованием в качестве продуктов гидролиза четырех мононуклеотидов.The strain of mold fungus Aspergillus clavatus 2286/5. The thickness of the conidiophores is up to 35 microns, the height is up to 1 mm, the size of blisters is 140-190X X64 microns. The size of the side sterigm is 1-9X2.5 lx, the upper 9-11X2.5 microns, conidia 4.5-5.0X3.0- -3.5 microns, heads 400-700 microns. Three colonies are 4.5 cm in diameter. The color of the colonies varies from bluish-green to dull gray-green. Synthetic medium, (glucose, peptone, soya flour and MgSO4-7H2O, CaCl2-2H20,5 KNOs). Mycelium is yellowish, branched hyphae, 450 w / s. The diameter of the hyphae, equal to 4-7 days of growth of 5.0-7.5 microns, after 72 hours of growth increases to 12 microns. Enzymatic properties. During deep growth, it releases a ribonucleic acid depolymerizing enzyme with the formation of four mononucleotides as hydrolysis products.
