Utilization of the herbicide phosphinothricin as a nitrogen source by soil bacteria

Rhodococcus sp., Pseudomonas paucimobilis and five other bacterial soil isolates were found to be capable of utilizing the L-enantiomer of the herbicide phosphinothricin (2-amino-4-(methylphosphinyl)-butanoic acid) as a nitrogen source. This deamination yielded the structural analogue, 2-oxo-4-(meth...

Description
Summary:Rhodococcus sp., Pseudomonas paucimobilis and five other bacterial soil isolates were found to be capable of utilizing the L-enantiomer of the herbicide phosphinothricin (2-amino-4-(methylphosphinyl)-butanoic acid) as a nitrogen source. This deamination yielded the structural analogue, 2-oxo-4-(methylphosphinyl)-butanoic acid as the main catabolite of phosphinothricin. On prolonged incubation, slow decarboxylation of the main catabolite occurred with the formation of the stable degradation product 3-methyl phosphinico-propanoic acid.
