| 20110027866 | CARRIER PIECE AND METHOD FOR PREPARING CULTURE MEDIA - The method provides a simple, accurate and inexpensive way to prepare culture media for conducting microbiological analysis with an absolute minimum of facilities, extraneous equipment and time consuming procedures. The invention introduces the use of a carrier piece that is suitable for carrying a reactant material for combining with growth media. The carrier piece may be formed using (non-)porous, (non-)absorbent material, including paper, plastic, gum, fabric, or acetate. The carrier piece carries a single one or a combination of various reactant materials that are released into the medium or medium/test sample mixture upon contact therewith. The reactant materials may include, among other things, nutrients, inhibitors, including antibiotics and bile salts, enzyme substrates, and/or a catalyst for a gelling agent contained in the growth medium. The growth medium, the carrier piece with the appropriate reactant material(s), and the test sample can be easily packaged and sold separately or as a kit and used anywhere. | 02-03-2011 |
