Abstract
The invention concerns novel 6- or 7-substituted derivatives of esculetin (6,7-dihydroxy-2H-1-benzopyran-2-one), their synthesis, and their application as substrates for the detection of micro-organisms in samples where a derivative is enzymatically cleaved to release a colored or fluorogenic marker which has a low tendency to diffuse through agar or other aqueous environments.
