Buffered charcoal yeast extract (BCYE) agar is a selective growth medium used to culture or grow certain types of bacteria, particularly the Gram-negative species Legionella pneumophila. It has also been used for the laboratory diagnosis of Acanthamoeba keratitis, Francisella and Nocardia. References Buffered Tryptone Glucose Yeast Extract Broth is also used to obtain pure cultures of C. perfringens before proceeding for confirmation. Endospores are not usually produced in this medium (1). The medium contains casein enzymic hydrolysate, peptic digest of animal tissue and yeast extract, which provides carbon and Jan 02, 2020 · Buffered Charcoal Yeast Extract (BCYE) Feeley et al in 1978 developed a medium to isolate Legionella species which was later modified by substituting yeast extract for casein hydrolysate and beef extract, and replacing starch with activated charcoal and named it as Charcoal Yeast Extract (CYE) Agar. Hardy Diagnostics Buffered Charcoal Yeast Extract (BCYE) Agar formulations are recommended for use in the cultivation and primary isolation of Legionella spp. in water and other samples suspected of harboring the bacteria.

Samples were plated onto buffered charcoal yeast extract (BCYE) agar and then incubated for 5-7 days at 35 C. The number of colony forming units(CFU) present were counted. Results: The 265 nm and 285 nm LEDs were most effective for inactivation of L. pneumophila, followed by the 255 nm LED and lastly the LP UV.

Hi, I'm trying to culture L. pneumophila in liquid culture using ACES buffered yeast extract broth (10g/L yeast extract, 0.4g/L L-cystein, 0.25g/L ferric pyrophosphate). Medium is filter sterilized. Francisella tularensis can be cultured aerobically using chocolate agar, buffered charcoal yeast extract agar, Thayer-Martin agar, Mueller-Hinton broth, etc. The organism grows slowly, so cultures often take 48 h to grow and plates should be observed daily for 10–14 days.
