Compositions having at least one biosurfactant and at least one persicomycin. The at least one biosurfactant is selected from the group consisting of rhamnolipids, glucolipids and sophorolipids. The compositions optionally have at least one enzyme, at least one non-biosurfactant and/or at least one selected from the group consisting of an anti-redeposition polymer and a soil release polymer. The compositions clean surfaces of an article in a process for cleaning said article.

Composition comprising biosurfactant and persicomycin (3-(3'hydroxy)hydroxy fatty acid)

An enzymatic method for the production of an L-glufosinate P-alkyl ester can be performed. This method is characterized by reacting an L-glufosinate P-alkyl ester carbamoylate to give the corresponding L-glufosinate P-alkyl ester. This is catalyzed by a carbamoylase. The L-glufosinate P-alkyl ester carbamoylate employed may be obtained by a reaction from the corresponding L-glufosinate hydantoin P-alkyl ester. This is catalyzed by a hydantoinase, preferably an L-enantioselective hydantoinase. In a second aspect, an enzymatic method for enantioselective production of an L-glufosinate P-alkyl ester from a mixture Mof L- and D-glufosinate P-alkyl ester hydantoins can be performed. The L-glufosinate P-alkyl ester obtained in the methods according to the first or second aspect of the invention may be saponified to give L-glufosinate.

Enzymatic method for the production of l-glufosinate p-alkyl esters

A first enzymatic method for the production of an L-glufosinate P-ester includes reacting an L-glufosinate P-ester carbamoylate to give the corresponding L-glufosinate P-ester in the presence of a carbamoylase as a catalyzer. A second enzymatic method includes the enantioselective production of an L-glufosinate P-ester from a mixture Mof L- and D-glufosinate P-ester hydantoins. The L-glufosinate P-ester obtained in the two methods may be saponified to give L-glufosinate.

Enzymatic method for the production of L-glufosinate P-esters

An enzymatically catalyzed method for producing L-glufosinate or a phosphoester of L-glufosinate can be performed. An activated L-homoserine His reacted with a substrate S selected from methylphosphinic acid and the esters of methylphosphinic acid. The method makes accessible new substrates in the enzymatic production of L-glufosinate and its phosphoesters.
