ON THE METHOD OF QUANTITATIVE ANALYSIS OF BACTERIA CULTURES IN FLUID MEDIA

Abstract

The fixed and dissolved samples are filtered through a membrane filter to determine their cell density in fluid bacteria cultures. The filter is stained while the bacteria are on it, cleared up on an object-rack and microscopically calculated. The advantages of this method are greater precision (average error 4 to 5%), greater usefulness (especially in the field of low concentration) and simplification of the test through lessened dependence on time.
