BCYE-Cys Agar Base

BCYE-Cys Agar Base is a specialized culture medium designed for the identification and confirmation of Legionella species in accordance with ISO standards. Widely applied in Legionella testing, water microbiology testing, and environmental surveillance, this medium plays a critical role in differentiating Legionella strains by evaluating their dependence on L-cysteine for growth. As a key component in modern Legionella detection workflows, BCYE-Cys Agar Base supports accurate confirmation of isolates recovered from potable water systems, cooling towers, healthcare facilities, and industrial water networks.

The formulation contains yeast extract, ACES buffer, activated charcoal, and α-ketoglutarate to provide essential nutrients while maintaining optimal growth conditions. Unlike standard BCYE media, BCYE-Cys Agar Base does not contain L-cysteine hydrochloride, making it an effective Legionella identification medium for confirming cysteine dependency. The activated charcoal enhances recovery performance by neutralizing inhibitory substances and supporting microbial growth during extended incubation.

Ideal for public health laboratories, environmental monitoring programs, and water quality testing facilities, this medium delivers reliable and reproducible results for ISO Legionella culture and confirmation procedures. Manufactured by Babio, a well-known Chinese manufacturer of microbiological culture media and laboratory diagnostic products, BCYE-Cys Agar Base provides dependable quality for professional microbiology laboratories worldwide.
