They require L-cysteine and iron salts for growth. Formula : gm/litre: Activated charcoal 2.0 Yeast extract 10.0 Agar 13.0 LEGIONELLA BCYE GROWTH SUPPLEMENT. Buffered charcoal yeast extract (BCYE) agar containing 0.1% alpha-ketoglutarate is the base medium used for the recovery of Legionella from environmental and clinical specimens (Appendix 1). Buffered Charcoal Yeast Extract Agar (BYCE Agar) is For the isolation, cultivation, and maintenance of Legionella pneumophila and other Legionella species from environmental and clinical specimens. in water and other samples suspected of harboring the bacteria. The medium demonstrated differential growth characteristics to aid in the identification of Legionella species. Legionella pneumophila (and 28 Legionella species) grew efficiently on charcoal-free, buffered yeast extract medium made with washed agar and without apparent loss of infectivity for U937 cells. They are nonfermentative as well as urease and nitrate negative. Legionellae are exacting in their growth requirements and grow best on buffered charcoal yeast-extract agar (BCYE), which contains iron plus cysteine as an essential growth factor. Legionella pneumophila colonies on BYCE Agar. The first, designated PCV, contains polymyxin B, cycloheximide, and vancomycin. Code: SR0110.
