Description
Verfahren zur Anreicherung tuberculocider Wirkstoffe In Escherichia coli bzw. in den Kulturflüssigkeiten von Escherichia coli sind antibiotisch wirksame Stoffe enthalten, die man als angereicherte Extrakte gewinnen kann, indem man beispielsweise die Bakterienmasse oder die Kulturflüssigkeiten von hesonders ausgelesenen aktiven Colistämmen mit lipoidlösenden Lösungsmitteln extrahiert. Als Ausgangsmaterial für die Gewinnung solcher Extrakte kann man auch Colibakterien benutzen, die nicht in besonders künstlich angelegten Kulturen gewonnen werden, sondern es können dazu auch Fäkalien solcher Lebewesen benutzt werden, die Escherichia coli in ihrem Verdauungstraktus beherbergen.Process for the enrichment of tuberculocidal active substances In Escherichia coli or in the culture fluids of Escherichia coli are antibiotically effective Contain substances that can be obtained as enriched extracts, for example by the bacterial mass or the culture fluids of specially selected active Coli strains extracted with lipoid-dissolving solvents. As a raw material for Coli bacteria can also be used to obtain such extracts, which are not found in especially artificially created cultures can be obtained, but it can do so feces of organisms such as Escherichia coli are also used in their digestive tract accommodate.
Solche Fäkalien sind jedoch im allgemeinen weniger geeignet als besonders gezüchtete antibiotisch aktive Stämme.However, such feces are generally less suitable than particularly cultivated antibiotic active strains.
Es wurde nun gefunden, daß die durch Extraktion mit lipoidlösenden Lösungsmitteln erhaltenen Extrakte, unabhängig von ihrer Herkunft, höhermolekulare gesättigte Fettsäuren, vorzugsweise Palmitinsäure, enthalten, und daß durch deren Abtrennung die tuberculocide Wirkung der Extrakte ganz außerordentlich ansteigt. It has now been found that by extraction with lipoid-dissolving Extracts obtained from solvents, regardless of their origin, are of higher molecular weight saturated fatty acids, preferably palmitic acid, and that by their Separation the tuberculocide effect of the extracts increases quite extraordinarily.
Beispiele I. 20 g eines Extraktes von Bact. coli, der durch Ätherextraktion eines im Vakuum aus der Bakterienmasse hergestellten Trockenpulvers erhalten worden war, zeigt bei der Prüfung seiner Bacterici die gegenüber Tuberkelbazillen noch eine sichere Wirkung in der Verdünnung I: 10000. Durch Ausfrieren der Palmitinsäure aus diesem Extrakt erhält man nach Absaugen der kristallisierten Anteile 3 bis 4 g eines Öls, das sich bis zur Verdünnung I.: 50000 bactericid wirkt. Examples I. 20 g of an extract from Bact. coli produced by ether extraction a dry powder produced in a vacuum from the bacterial mass been was, in the examination of its Bacterici, the opposite to tubercle bacilli still shows a safe effect in the dilution I: 10000. By freezing out the palmitic acid 3 to 4 are obtained from this extract after the crystallized portions have been filtered off with suction g of an oil that has a bactericidal effect up to the dilution I .: 50000.
2. Durch Ätherextraktion von im Vakuum bei einer Temperatur von maximal 400 getrocknetem menschlichem Fäces erhält man nach restloser Entfernung des Extraktionsmittels ein Ö1, das teilweise zum Kristallisieren neigt. Die tuberculociden Eigenschaften dieses Öls werden durch Entfernung dieser Kristalle, die aus Palmitinsäure bestehen, auf das Doppelte gesteigert. 2. By ether extraction in a vacuum at a temperature of maximum 400 dried human feces are obtained after the extraction agent has been completely removed an oil that partially tends to crystallize. The tuberculocidal properties of this oil, by removing these crystals, which consist of palmitic acid, doubled.
