Изобретение относитс  к области микробиологического синтеза белково-витаминных веществ на основ.е углеводородов пефти.The invention relates to the field of microbiological synthesis of protein-vitamin substances based on hydrocarbons and oil.

Известен способ выделени  биомассы микроорганизмов , например, дрожжей, из культуральной среды путем добавлени  в последнюю осадител  при перемешивании и нагревапии .There is a method for isolating the biomass of microorganisms, for example, yeast, from the culture medium by adding to the last precipitant with stirring and heating.

Цель изобретени  - улучшение условий выделени .The purpose of the invention is to improve the conditions of excretion.

Это достигаетс  тем, что в качестве осадител  используют хлористый калий в количестве , предпочтительно равном 0,04-0,1% к объему среды.This is achieved by using potassium chloride as a precipitator in an amount preferably equal to 0.04-0.1% by volume of the medium.

Пример. Химический стакан емкостью 300 мл, снабженный мешалкой, помещают на вод ную баню с температурой 35°С. В него ввод т бномассу в количестве 10 мл и хлористый калий, после пего содержимое стакана перемешивают в течение 10 мин. Затем суспензию перенос т в стаканчики лабораторной иентрифуги (5000 об/мин) и центрифугируют в течение 3 мин. Надосадочна  жидкость декантируетс , и в ней при помощи камеры Гор ева под микроскопом подсчитывают число дрожжевых клеток.Example. A 300 ml beaker equipped with a stirrer is placed in a water bath at a temperature of 35 ° C. 10 ml of potassium chloride and potassium chloride are introduced into it, and then the contents of the glass are mixed for 10 minutes. The suspension is then transferred to laboratory centrifuge cups (5000 rpm) and centrifuged for 3 minutes. The supernatant is decanted and the number of yeast cells is counted under a microscope using the Gorev camera.

Дл  сравнени  став т контрольный опыт: биомасса без добавлени  хлористого кали  подвергаетс  такой же обработке, как и в рабочем опыте.For comparison, the control experiment was performed: the biomass without the addition of potassium chloride was subjected to the same treatment as in the working experiment.

Результаты представлены в таблице, показывающей уменьшение количества дрожжевых клеток в надосадочиой жидкости после добавлени  хлористого кали  к биомассе при 35°С (клеток в 56 квадратах камеры Гор ева ).The results are presented in a table showing a decrease in the number of yeast cells in the supernatant fluid after adding potassium chloride to the biomass at 35 ° C (cells in 56 squares of the Gorev chamber).

Таким образом, добавлением хлористого кали  к биомассе в количестве 0,04 и 0,1%Thus, by adding potassium chloride to the biomass in an amount of 0.04 and 0.1%

позвол ет уменьшить число дрожжевых клеток в культуральной среде после центрировани  биомассы в 5,5 раза в первом случае и 5,8 раза во втором. Унос дрожжей в контрольном опыте составл ет 0,218-0,200 г/л, послеallows to reduce the number of yeast cells in the culture medium after centering the biomass by 5.5 times in the first case and 5.8 times in the second. The yeast ablation in the control experiment is 0.218-0.200 g / l, after

добавлени  хлористого кали  0,0375 г/л, т. е. уменьщаетс  на 82%.addition of potassium chloride 0.0375 g / l, i.e., reduced by 82%.

Предмет изобретени Subject invention

Способ выделени  -биомассы микроорганизмов , например дрожжей, из культуральной 3 среды путем добавлени  в последнюю осадител  при перемешивании и нагревании, отличающийс  тем, что, с целью улучшени  уело4 вий выделени , в качестве осадител  используют хлористый калий в количестве, предпочтительно равном 0,04-0,1% к объему среды.The method for isolating the -biomass of microorganisms, e.g. 0.1% by volume of the medium.
