Incubate. If examination discloses no evidence of tubes possessing alkaline (purple) slants and acid (yellow) butts (with or without concomitant blackening from the butt from hydrogen sulfide manufacturing), the specimen fulfills the requirements in the test to the absence on the genus Salmonella.
For your fluid specimen in aerosol variety, chill the container in an Liquor-dry ice mixture for about one hour, Reduce open the container, enable it to reach home temperature, permit the propellant to escape, or heat to generate off the propellant if possible, and transfer the amount of test material necessary for that procedures laid out in one of many two previous paragraphs, as ideal.
