Abstract
The present invention is directed to methods and compositions for the characterization of various microorganisms. In particular, the present invention is suited for the characterization of commonly encountered microorganisms (e.g., E. coli, S. aureus, etc.), as well as commercially and industrially important organisms from various and diverse environments. For example, the present invention is particularly suited for the growth and characterization of the actinomycetes and fungi. The methods employ a testing system wherein an aqueous suspension of microorganisms is introduced to one or more test substrates comprising redox purple (8-hydroxy-11-methyldibenz-b,e!1,4!oxazepin-2-(11H)-one) and a gelling agent. The methods detect the response of the microorganisms to the test substrates. A testing device comprising a plurality of testing wells is well suited for the present invention.
