Chromatographic determination of morpholine and products of its microbiological degradation

A combination of thin-layer chromatography (TLC) with high-performance liquid chromatography (HPLC) was shown to be efficient in determining the intermediate products of the utilization of thiomorpholine with ligninolytic basidiomycete fungus Bjerkandera adusta VKM F-3477. The chromatographic mobility of the products of microbiological degradation of thiomorpholine was studied on Sorbfil PTSKh-P-V plates in the systems of chloroform-methanol-25% aqueous ammonia (80: 20: 2) for determining cyclic amines and isopropanol-25% aqueous ammonia (70: 30) for determining thio acids. The optimum conditions were selected for the separation of thiomorpholine and the formed metabolites by ion-exchange chromatography and reversed-phase chromatography.
