EMI2.1
Zusammensetzung wurde nach vierwöchentlichem Wachstum nicht weniger als 4 9 scharf getrockneter Tuberkelbazillen gewonnen. Diese Tuberkelbazillen wurden einer quantitativen Analyse unterworfen und gefunden, dass sie einen Arsengehalt von 0'006 g, berechnet auf AS203' pro 1 9 Trockensubstanz enthielten.
Was nun die Nährbouillon anbelangt, aus welcher die Tuberkelbazillen durch ihre Entwicklung einen Teil des ursprünglichen Arsengehaltes entnommen hatten, so wurde gefunden, dass das Arsen, welches der Bouillon als arsenige Säure zugesetzt worden war, nach Beseitigung

EMI2.1
Composition was recovered after four weeks of growth not less than 49 sharp-dried tubercle bacilli. These tubercle bacilli were subjected to a quantitative analysis and found that they contained an arsenic content of 0'006 g, calculated on AS203 'per 19 dry matter.
As for the nutrient broth, from which the tubercle bacilli had withdrawn part of the original arsenic content through their development, it was found that the arsenic, which had been added to the broth as arsenic acid, after elimination
EMI2.2
This fact was initially recognized by the fact that when the arsenic-tuberculosis broth was filled with alcohol, by far the largest proportion of the arsenic which, according to the calculation, was still in the broth

PATENT CLAIMS:
1. Process for the production of particularly effective tubercle bacilli cultures. consisting in growing tubercle bacilli on arsenic-containing culture media.
