Andrade Peptone Water with HiVeg Extract No. 1, 2.5KG

Andrade Peptone Water w/ HiVeg™ Extract No. 1 is a basal medium for studying fermentation reactions, particularly of members of the Enterobacteriaceae. This medium is the most commonly used media for carbohydrate fermentation. Desired carbohydrate is added to the medium, which is inoculated with the test organism. If the test organism metabolizes the added carbohydrate, acids are produced, thereby lowering the pH of the medium. This causes a subsequent color change of the indicator, from colorless to pink to red. If the added carbohydrate is not metabolized, the medium remains pale tan to straw colored. Gas produced during fermentation is collected in the Durhams tube. Appearance of Powder: Light yellow colored with pink tinge, homogeneous, free flowing powder Color and Clarity: Light pink colored, clear solution without any precipitate Reaction of 1.81% w/v aqueous solution of MV909 is pH 7.1 ± 0.2 at 25°C Cultural characteristics observed after an incubation at 35-37°C for 18-24 hours
