(54) СПОСОБ ОЧИСТКИ АГАР-АГАРА(54) METHOD OF CLEANING AGAR-AGARA
I -..,I - ..
Изобретение относитс к ветеринарной и медищтаской микробиологии и другим смежным област м, где используетс агаровый гель высокой степетш прозрачности , а более конкретно - к лабораторной диагностике тфекдионньтх заболеваний при помощи реакции диффузной преципитации.The invention relates to veterinary and medical microbiology and other related areas where agar gel of high degree of transparency is used, and more specifically to laboratory diagnosis of infectious diseases using diffuse precipitation.
Известен способ очистки (осветлетш ) агар-агара, при помощи длительных про1ЛЫВОК в водопроводной и дистиллирован- ,Q ной воде .The known method of purification (clarification) of agar-agar, with the help of prolonged pro- cesses in tap water and distilled water.
Недостатком этого способа вл етс то, что расходуетс много времени на промывку агара и не достигаетс необходима прозрачность конечного продук- 5 та очистки.The disadvantage of this method is that it takes a lot of time to rinse the agar and the transparency of the final cleaning product is not achieved.
Известен способ очистки агар-агара, при помощи взбитого до пенообразного состо ни водного раствора белка кзфиного йца 2} .20A known method of purification of agar-agar, using an aqueous solution of green yeast protein 2, whipped to a foamy state. 20
Недостатком данного способа вл етс кютаченйе смеси расплавленного в дистиллированной воде агара с ичньтм белком.The disadvantage of this method is kutchenye mixture melted in distilled water of agar with the ichtym protein.
.а полученный после фильтрации продукт очистки недостаточно прозрачен..a the purification product obtained after filtration is not transparent enough.
Известен также способ очистки агарагара при помощи хлористого кальпи и длительных промывок порезанного на кусочки застывшего гел в водопроводной и дистилшфованйой воде 3 .There is also known a method of cleaning an agargar with the help of calpy chloride and long washes of cut gelized gel in tap and distilled water 3.
Недостаток указанного способа состоит в том, что несмотр на сложность методики и больщие затраты рабочего времени на очистку агара, не достигаетс главна цель - получени после очистки тел высокой степени прозрачности.The disadvantage of this method is that, despite the complexity of the technique and the high labor costs of cleaning the agar, the main goal is not achieved - to obtain, after cleaning the bodies, a high degree of transparency.
Целью насто щего изобретени вл етс повышение качества и сокращени сроков очистки агар-агара.The object of the present invention is to improve the quality and shorten the time required for purifying agar-agar.
Поставленна цель достигаетс тем, что замачивание агар-агара провод т в дистиллированной воде с рН 7,0-7,2, а осветление осуществл ют после предварительного охлаждени расплава агар-агара до 45-50 С и обработки раствором хлористого кальци при нагревании смеси в присутствии ичного белка до образовани The goal is achieved by soaking the agar-agar in distilled water with a pH of 7.0-7.2, and clarification is carried out after pre-cooling the agar-agar melt to 45-50 ° C and treating the calcium chloride solution while heating the mixture in the presence of egg protein to form
