Non-Lactose fermenting bacteria such as Salmonella, Proteus species, Yersinia, Pseudomonas aeruginosa and Shigella cannot utilize lactose, and will use peptone instead. This forms ammonia, which raises the pH of the agar, and leads to the formation of white/colorless colonies on the petri plate.t contains bile salts (to inhibit most Gram-positive bacteria), crystal violet dye (which also inhibits certain Gram-positive bacteria), neutral red dye (which turns pink if the microbes are fermenting lactose). Composition: 1  Peptone - 17 g. 2  Proteose peptone - 3 g.
ABSTRACT. The presence of lactose-fermenting Salmonella strains in clinical case materials presented to microbiology laboratories presents problems in detection and identification. Failure to detect these strains also presents a public health problem.s early as 1887, it was known that Escherichia coli was a lactose fermenter and that Salmonella was not a lactose fermenter. Therefore, most differential plating media commonly developed and used today for the isolation of Salmonella contain lactose (16, 17, 31).
