METHOD FOR DEMONSTRATING AN ENZYMATIC ACTIVITY OF MICRO-ORGANISMS

摘要

The method consists in the use of one compound of formula: X-NH-R in which X represents one 5-bromoindole-3-yle group and R represents the acyl radical of one amino acid selected between leucine and alanine, as tracer for demonstrating, by the formation of a coloured product, a peptidase activity in a culture of micro-organisms.
