Description
редукции метиленового синего. Ферментацию углеводов определ ют по изменению цвета среды в кислую зону , уреазную активность - по изменению реакции нижнего сло среды в щелочную зону, газообразование по образованию пузырьков газа в толще среды (при ферментации только глюкозы) и по разрывам столбика (при ферментации лактозы и (или сахарозы), продукФерментаци reduction of methylene blue. The fermentation of carbohydrates is determined by the color change of the medium to the acidic zone, the urease activity is determined by the change of the reaction of the lower layer of the medium to the alkaline zone, gas formation by the formation of gas bubbles in the thickness of the medium (when only glucose is fermented) and by the breaks of the bar (when lactose is fermented and (or sucrose), products

На основании проведенных иcпытa ий , установлено 100%-ное совпадение всех признаков с классическим методом.On the basis of the conducted tests, a 100% match of all signs with the classical method was established.
Полученные результаты позвол ют правильно и быстро определить Ь приз- 60 наков энтеробактерий, экономить посуду и врем .The obtained results make it possible to correctly and quickly determine the characters of enterobacteria, save dishes and time.
Предлагаемый, способ не требует много времени, дефицитных реактивов, среда может быть приготовлена в любых в5The proposed method does not require much time, deficient reagents, the medium can be prepared in any way5
цию сероводорода - по образованию черного кольца в столбике на границе нижнего и верхнего слоев. Изменени цвета индикатора в комбинации с различн лми степен ми редукции метиленового синего дают разные оттенки, придава нижней части среды полихромный характер.hydrogen sulfide is formed by the formation of a black ring in the column on the border of the lower and upper layers. Changes in the color of the indicator in combination with varying degrees of methylene blue reduction give different shades, giving the lower part of the medium a polychrome character.

услови х,способ позвол ет четко дифференцировать основные группы энтеробактерий и смежных семейств и может быть использован в больничных лаборатори х при исследовани х экскретов больных, а также при санитарно-бактериологических исследовани х.conditions, the method allows to clearly differentiate the main groups of enterobacteria and adjacent families and can be used in hospital laboratories in the study of excreta of patients, as well as in sanitary-bacteriological studies.
