Description
Существующие способы определени токсичности грибов, выдел емых из кормов и натологических материалов, представл ют собой комнлекс СЛОЖНЫХ, продолжительных и дорогосто щих исследований.Existing methods for determining the toxicity of fungi released from feed and natural materials are a complex of complex, lengthy and expensive studies.
Предлагаемый способ позвол ет в течение времени от 3 мин до 2 час определить токсичность культуры гриба, благодар использованию тестобъекта протозоа.The proposed method makes it possible to determine the toxicity of the culture of the fungus over a period of time from 3 minutes to 2 hours, thanks to the use of a protozoa test object.
Способ быстрого определени токсичности грибов заключаетс в следующем. Культура гриба, выделенна обычным микологическим методом на ПЛОТНОЙ питательной среде, отдел етс от нее и экстрагируетс при температуре минус 4° нейтральной водопроводной водой в течение суток. Затем на предметное стекло нанос т одну каплю культуры протозоа Paramaecium caudatum или Tetrahymena pyriformis.A method for rapidly determining the toxicity of fungi is as follows. The culture of the fungus, isolated by the usual mycological method on a DILIC nutrient medium, is separated from it and extracted at a temperature of minus 4 ° with neutral tap water for a day. Then, one drop of Paramaecium caudatum or Tetrahymena pyriformis protozoan culture is applied to a glass slide.
Под воздействием экстрактов из культур грибов гибель и разрущение простейщих организмов наступает в течение не более 3 мин при воздействии резкотоксичных щтаммов, в течение не более 8 мин при воздействии токсичных щтаммов и в течение не более 1-2 час при воздействии слаботоксичных щтаммов.Under the influence of extracts from cultures of fungi, death and destruction of simple organisms occurs within no more than 3 minutes when exposed to sharply toxic substances, within no more than 8 minutes when exposed to toxic substances and for no more than 1-2 hours when exposed to weakly toxic substances.
Предмет изобретени Subject invention
Способ определени токсичности грибов, отличающийс тем, что, с целью ускорени определени токсичности грибов, поражающих корма, в качестве тест-объекта используют протозоа Paramaecium caudatum или Tetrahymena pyriformis.The method of determining the toxicity of fungi, characterized in that, in order to accelerate the determination of the toxicity of fungi that infect fodder, the protoma Paramaecium caudatum or Tetrahymena pyriformis is used as a test object.
