Abstract

Mannose-2-14C has been fermented by Leuconostoc mesenteroides. CO2, ethanol and d-lactic acid were formed in a molar ratio of 1:1:1. A small amount of acetic acid was found as by-product. It could easily be isolated from the main products of the fermentation and it did not disturb further degradation procedures. The methyl-C-atom of ethanol, which was derived from C-2 of the mannose, had nearly the same specific radioactivity as mannose-2-14C. All other C-atoms of the degradation products were only very slightly labeled. Their content of radioactivity was in any case lower than 3% of the specific radioactivity of the degraded mannose. This procedure is applicable for the degradation of 14C-labeled mannose.

Zusammenfassung

Mannose-2-14C wurde mit Leuconostoc mesenteroides fermentativ gespalten. CO2, Äthanol und d-Milchsäure wurden im molaren Verhältnis 1:1:1 gebildet. Als Nebenprodukt fanden wir eine geringe Menge Essigsäure. Diese konnte von den Hauptprodukten der Fermentation leicht abgetrennt werden und störte daher deren weitere Degradation nicht. Das Methyl-C-Atom des Äthanols, das vom C-2 der Mannose stammt, hatte nahezu die gleiche spezifische Radioaktivität wie die Mannose. Alle übrigen C-Atome der Abbauprodukte waren nur sehr schwach markiert. Ihr Radioaktivitätsgehalt lag in jedem Fall unterhalb 3% der spezifischen Radioaktivität der eingesetzten Mannose. Dieses Verfahren eignet sich daher zur spezifischen Degradation 14C-markierter Mannose.
