Abstract:
A simple culture medium, comprising (a) an adhesive, (b) a gelling agent, (c) a bacterial nutritive ingredient, a fibrous water-absorbent sheet, and a waterproof flat plate, produced by a process comprising:preparing an alcohol suspension by suspending in an alcohol (a) an adhesive, which is soluble in both water and alcohol, and is a hydroxypropyl cellulose, at a final concentration of 0.01 to 0.4% w/v (b) a gelling agent, which is soluble in water and insoluble in alcohol, and (c) a bacterial nutritive ingredient; impregnating a fibrous water-absorbent sheet with the alcohol suspension, wherein the fibrous water-absorbent sheet has a mesh larger than the particle size of the gelling agent and being placed on a waterproof flat plate; and drying the resultant sheet while suppressing rapid evaporation of alcohol, to thereby cause the water-absorbent sheet to adhere onto the waterproof flat plate.
