Brilliant green agar medium

Brilliant green agar medium

Brilliant green agar is a selective solid medium for the separation of Salmonella, especially suitable for the detection of clinical and food samples. Its selectivity mainly depends on the brilliant green dye, which can effectively inhibit the growth of common intestinal bacteria such as Gram-positive bacteria and Escherichia coli, while allowing the development of Salmonella and some Shigella. Peptone and yeast extract in the culture medium provide basic nutrition, and lactose, sucrose and phenol red indicators are used to identify fermentation characteristics. Typical Salmonella does not ferment lactose and sucrose, the colony is transparent or reddish, and the color of the surrounding culture medium remains unchanged (red/alkaline); However, the mixed bacteria that ferment lactose make the colony yellow and the surrounding culture medium yellow. This culture medium has strong selectivity and is one of the classic methods for salmonella isolation.
