Summary
Strains of the species Klebsiella oxytoca growing on glucose or gluconate medium accumulate 2,3-dihydroxybenzoic acid, its serin and threonine derivative. These strains also accumulate two compounds exhibiting fluorescence under ultraviolet radiation. One of these is probably a phosphoric ester. The formation of both substances could be partially inhibited by the tryptophane.
Zusammenfassung
Es wurde gefunden, daß Klebsiella oxytoca-Stämme auf Glucose- oder Gluconat-haltigen Nährböden neben 2,3-Dihydroxybenzoesäure deren Serin- und Threoninderivat anhäufen. Von den zwei unter UV fluorescierenden Substanzen, die außerdem von diesen Stämmen gebildet werden, ist die eine wahrscheinlich ein Phosphorsäurederivat. Tryptophanzugabe zu den Kulturmedien hinderte die Bildung dieser Substanzen zum Teil.
