I. Safarik et M. Safarikova, A MODIFIED PROCEDURE FOR THE DETECTION OF MICROBIAL PRODUCERS OF EXTRACELLULAR PROTEOLYTIC-ENZYMES, Biotechnology techniques, 8(9), 1994, pp. 627-628
A simple procedure for the detection of microbial producers of proteol
ytic enzymes using dyed gelatin microcarrier particles incorporated in
to appropriate nutrient agar is described. Extracellular proteinases p
roduced by the tested microbial strains hydrolyzed the substrate and c
lear dyed zones around and under the colonies were formed.
