Yeast extract peptone dextrose (YPD or YEPD) Growth Agar is used for the maintenance and propagation of yeasts including S. cerevisiae in various molecular microbiology procedures. YPD functions as a complete medium for yeast growth.
The medium is identical to Buffered Charcoal Yeast Extract (BCYE) agar except for the addition of the four selective compounds. Yeast extract provides sources of nitrogen, carbon and vitamins. Activated charcoal neutralises toxic metabolic by-products and ACES and potassium hydroxide buffer the media to the optimum pH. Introduction to Yeast Media | Sigma-Aldrich A nutritious medium available in liquid (broth) or solid (agar) forms for the growth and propagation of yeast cultures. It primarily contains of bacteriological peptone, yeast extract, and glucose. This medium is non-selective for Candida, Pichia, Saccharomyces, and Zygosaccharomyces. 2. Yeast Synthetic Drop-out Medium Supplements Yeast extract agar | definition of yeast extract agar by Sputum samples were obtained from 211 of the 286 patients and sent to the laboratory of China CDC (Beijing, China) for Legionella culture, which used both buffered charcoal yeast extract agar and buffered charcoal yeast extract agar supplemented with Legionella GVPC (glycine, vancomycin, polymyxin, cycloheximide) Selective Supplement (Oxoid, https://www.thermofisher.

The lower photograph illustrates colonies growing on a buffered charcoal yeast extract agar plate that had been inoculated with material from the ulcer bed three days before. Tiny, pale-staining gram negative coccobacilli were seen on gram stain. The most likely causative agent is:
The lower photograph illustrates colonies growing on a buffered charcoal yeast extract agar plate that had been inoculated with material from the ulcer bed three days before. Tiny, pale-staining gram negative coccobacilli were seen on gram stain. The most likely causative agent is: Culturing, media, and handling of legionella.
Buffered charcoal yeast extract agar (BCYE) was developed by Feeley et al and then further modified by Edelstein for selective cultivation of Legionella species. BCYE Agar is an enrichment medium that is used for the isolation and cultivation of Legionella species from environmental samples and …
Charcoal-yeast extract agar is a new bacteriological medium that supports excellent growth of the Legionella pneumophila. It results from modifications made in an existing L. pneumophila medium, F-G agar. Yeast extract, instead of an acid hydrolysate of casein, serves as the protein source. Beef extractives and starch are not added.
