Adams Agar 500G

Adams Agar is recommended for examining sporulation in yeasts. Adams described a modified Stantial acetate medium consisting of low concentrations of glucose, sodium acetate, and agar upon which he obtained high yields of asci with a large number of yeast cultures. Although, in his original experiments, he tested a variety of acetate salts, including potassium acetate, he found none of them superior to sodium acetate in about 0.24 per cent concentration. Dextrose in the medium stimulates sporulation. Acetate and dextrose are used as carbon sources.
