Abstract: This application claims a method for detecting biologically active substances, comprising the following steps a) providing a support carrying substances to be tested b) providing a suspension containing luminescent microorganisms, c) coating the support with the suspension of microorganisms, d) detecting the biologically active substances on the support by detecting the change in luminescence of the suspension of microorganisms, and e) stimulating the luminescence of the microorganisms before or during detection, and/or f) extending the period of luminescence of the microorganisms by employing substances for regulating and extending the period of luminescence of the microorganisms.

Abstract: The invention claimed herein is a kit for detecting biologically active substances on a support, comprising the luminescent marine bacteria Vibria Fischeri in a form stabilized for transport and storage, one or more cultivation media or the individual components of cultivation media for the microorganism wherein the cultivation media contains 100 mg/l to 500 mg/l of aspartic acid, and optionally additives for extending the period of luminescence selected from N-acylhomoserine lactones, dipeptides, oligopeptides, or their biochemical precursors, and boron compounds.

Abstract: The invention relates to a method for detecting biologically active substances, comprising the steps
