Summary

B. sphaericus is degrading the acylamides monalide, carboxin, oxycarboxin, 2,5-dimethylfurancarboxylic acid anilide, pyracarbolid, 2-methyl-and 2-chloro-benzoic acid anilide, the N′-phenylcarbamate propham and the N′-methoxyphenylurea compounds monolinuron, linuron, metabromuron and maloran by cleaving the amide linkage, forming the corresponding anilines and acids.

The metabolites were determined qualitatively by the means of co-thinlayer- and co-gaschromatography.

A pathway for degradation of the phenylamides by B. sphaericus is proposed.

Zusammenfassung

Die Acylanilide Monalide, Carboxin, Oxycarboxin, 2,5-Dimethylfurancarbonsäureanilid, Pyracarbolid, 2-Methyl- und 2-Chlorbenzoesäureanilid, der N′-Phenylcarbaminsäureester Propham und die N-Phenylharnstoff-derivate Monolinuron, Linuron, Metobromuron und Maloran wurden durch B. sphaericus an der Amidbindung zu den entsprechenden Anilinen und Säuren gespalten.

Der qualitative Nachweis der Zwischenprodukte gelang dünnschicht- und gaschromatographisch mit Hilfe von Vergleichssubstanzen.

Für den Abbau der Phenylamide durch B. sphaericus wurde ein Abbauschema aufgestellt.
