Claims (4)

1. Штамм Bacillus thuringiensis Н8 ВНИИгенетика 16-931 (ВКПМ В-6649) - продуцент эндотоксина против жесткокрылых насекомых.1. The strain Bacillus thuringiensis H8 VNIIgenetics 16-931 (VKPM B-6649) - producer of endotoxin against beetles. 2. Способ культивирования продуцента эндотоксина В.Т. в ферментере с использованием питательной среды, содержащей дрожжи и другие компоненты, с применением посевного бачка для введения посевного материала, отличающийся тем, что, с целью повышения производительности ферментера, процесс биосинтеза эндотоксина осуществляют путем проведения последовательных циклов, каждый из которых включает две стадии: на первой, активной стадии (рост культуры до начала споруляции) используют ферментер, в качестве посевного материала применяют культуральную жидкость, оставляемую в ферментере в количестве 5 - 10% от объема КЖ после окончания предыдущей активной стадии, а на второй, пассивной стадии (споруляции культуры и образование кристаллов эндотоксина) применяют емкость-дображиватель, не оснащенную системами термостатирования, аэрирования и перемешивания, требующими затрат энергии. 2. A method of cultivating an endotoxin producer V.T. in a fermenter using a nutrient medium containing yeast and other components, using a seed tank for introducing seed material, characterized in that, in order to increase the productivity of the fermenter, the process of endotoxin biosynthesis is carried out by conducting sequential cycles, each of which includes two stages: the first, active stage (growth of the culture before sporulation begins) use a fermenter, as a seed, use the culture fluid left in the fermenter in an amount of 5 - 10% of the amount of QOL after the end of the previous active stage, and at the second passive stage (sporulation of the culture and the formation of endotoxin crystals), an expansion tank is used that is not equipped with thermostatic, aeration and mixing systems that require energy. 3. Способ по п.2, отличающийся тем, что дображивание КЖ ведут при температуре 4 - 33oC, предпочтительнее при 20oC.3. The method according to claim 2, characterized in that the fermentation of the QOL is carried out at a temperature of 4 - 33 o C, preferably at 20 o C. 4. Способ по п.2, отличающийся тем, что надосадочную жидкость, остающуюся после концентрирования эндотоксина, применяют для приготовления новой порции ферментационной среды. 4. The method according to claim 2, characterized in that the supernatant remaining after concentration of endotoxin is used to prepare a new portion of the fermentation medium.
