A microbiological process for the production of S-(+)-2,2-dimethylcyclopropanecarboxamide, starting from R,S-(.+-.)-2,2-dimethylcyclopropanecarboxamide. For this process, new microorganisms are selected and isolated, which are capable of biotransforming R-(-)-2,2-dimethylcyclopropanecarboxamide in racemic 2,2-dimethylcyclopropanecarboxamide to R-(-)-2,2- dimethylcyclopropanecarboxylic acid. The process can then be performed either with the microorganisms or with the cell-free enzymes from the microorganisms.
