[Kinetics of production of collagenase, esterase and elastase by human and soil strains of "Entomophthora coronata" (author's transl)].

A comparative study was made of the production of extracellular proteolytic enzymes, which were originated from two different strains, one pathogenic and one saprophytic, of E. coronata in stable culture at 30 degrees C. Quantitative differences were found: the maximal activity of the three enzymes (collagenase, esterase, elastase) produced by the strain isolated from soil was always lower than that observed with the human strain.
