Title (EN) METHOD FOR COUNTING NUMBER OF MICROORGANISMS
(FR) PROCÉDÉ DE COMPTAGE DU NOMBRE DE MICRO-ORGANISMES
Abstract:
(EN) Provided is a method for simply and accurately counting the number of microorganisms in an analyte containing carbonate ion or bicarbonate ion in a dialysis fluid or the like. A counting method for the number of microorganisms includes: a step of adding the analyte to a composition for preparing a medium for counting the number of microorganisms, and containing (a) polyacrylic acid and/or a salt thereof, (b) hydroxide of alkaline earth metal and (c) a nutritional ingredient, and mixing the resulting mixture; a step of culturing microorganisms contained in the analyte; and a step of counting the number of colonies of the microorganisms.
(FR) L'invention concerne un procédé de comptage de manière simple et précise du nombre de micro-organismes dans un analyte contenant des ions carbonate ou des ions bicarbonate dans un liquide de dialyse ou analogue. Un procédé de comptage du nombre de micro-organismes comprend : une étape consistant à ajouter l'analyte à une composition pour préparer un milieu pour compter le nombre de micro-organismes, et contenant (a) de l'acide polyacrylique et/ou un sel de celui-ci, (b) de l'hydroxyde de métal alcalino-terreux et (c) un ingrédient nutritionnel, et à mélanger le mélange ainsi obtenu ; une étape consistant à cultiver les micro-organismes contenus dans l'analyte ; et une étape consistant à compter le nombre de colonies des micro-organismes.
