Seven Frankia strains from Casuarina and Allocasuarina were analyzed by polyacrylamide gel electrophoresis to determine the patterns of several enzymes. No relatedness could be established between the strains as far as polyphenol oxidase, esterase and diaphorase were concerned. A first attempt at grouping the Frankia isolates could be achieved with catalase. It was confirmed by the study of superoxide dismutase: only one activity band, with the same mobility, was found in all cases. We propose to use this enzyme as a marker for identification of Frankia strains issued from Casuarinaceae.
