Abstract

1502674 Compositions for generating CO 2 or SO 2 MILES LABORATORIES Inc 22 April 1975 [25 April 1974(3)] 16645/75 Heading C 1A [Also in Divisions C6 and G1] Apparatus for culturing and identifying a microorganism in an anaerobic environment, e.g. Neisseria gonorrhoeae in an atomosphere of carbon dioxide, consists in a preferred embodiment of a polystyrene base 10, Fig. 1, having an upstanding rectangular wall 12 and a transverse wall 21 having an upper surface 22 below the level of the upper surface 19 of wall 12, and a polyethylene cover 17. The walls 12 and 21 define spaced rectangular wells 13 and 14 in which are disposed a nutrient gel layer or dry nutrient pad 15 and a gas-generating composition in the form of a pad or film 16 responsive to water vapour evolved by the reconstituted nutrient medium. In a modification the gasgenerating composition is carried by the cover. In other embodiments, a rectangular base has the nutrient pad and a gas generating pad or film attached to it, and the assembly is enclosed in a sealable plastics bag. The carbon-dioxide-generating composition includes, additional to the conventional acid and carbonate, a water-soluble polymeric substance and a water-insoluble polymeric substance in relative proportions between 1:9 and 9:1, preferably between 1:3 and 3:1, by weight. The water-insoluble polymer moderates the evolution of gas and also serves as a supporting matrix. Water-soluble polymeric substances: hydroxypropyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose, polyacrylamide or polyvinyl alcohol. Water-insoluble polymeric substances: cellulose acetate, cellulose nitrate, cellulose acetate butyrate, ethyl cellulose, butyl cellulose, polybutadiene or polystyrene, also alginate or carrageen. Acids (conventional): citric, malic, fumaric, tartaric or maleic acid, or a corresponding anhydride. Carbonates (conventional): dibasic alkali metal carbonate, alkali metal bicarbonate or alkaline earth metal carbonate. Example 2 discloses the preparation of films or pads of effervescent composition in which acetone solutions of hydroxypropyl cellulose and cellulose acetate (ratios 3:1, 2:2, 1:3) containing citric acid and sodium bicarbonate were cast on glass plates or filter paper and the solvent allowed to evaporate. According to a modification, a steady, controlled humidity-activated sulphur dioxide source may be similarly provided by using an organic acid and an inorganic sulphite as the solid reactants in such a composition.
