Solid culture medium for microorganisms, process for its preparation, and use

摘要

The object of the invention is a microbe culture medium which can be activated with a liquid sample or water. Covalently crosslinked cellulose ethers are used as a gelling agent. The gel into which nutrients have been mixed is dried on a water-impermeable support. The culture medium according to the invention may be utilized for detecting bacteria and fungi both in the hygiene control of industry and in medical diagnostics. The same method principle may be used within different sensitivity ranges as the absorption capacity of the gel may be regulated according to the hydrophilicity of cellulose ethers.
