ABSTRACT:
A medium for biological analysis by biochemical means involving chromogenic or fluorogenic substrates that react with enzymes (esterases and/or osidases and/or peptidases and/or sulfatases and/or phosphatases) specific for the target strains is that is in a stable, ready-to-use liquid or gel form and contains at least one emulsifying stabilizer of the fatty acid sorbitan ester/fatty acid type and at least one solvent (dimethyl sulfoxide). This medium is obtained by mixing a stock solution of esterase and/or osidase and/or peptidase and/or sulfatase and/or phosphatase substrates in the solvent, and the emulsifying stabilizer, with some of the constituents of the culture medium.
