制备说明

Suspend 6.6 g of Lysine Medium in 100 ml of distilled water containing 0.84 ml of potassium lactate solution ~60% (Cat. No. 60389). Boil to dissolve the medium completely. Cool to 50 ℃. Adjust the pH to 5.0 with a 10% solution of Lactic Acid (Cat. No. 69778) and pour into sterile petri plates.NoteThe degree of contamination is expressed as the number of wild yeast cells per million cells of the original inoculum. The number of cells in the inoculum is important as a small number (100-1000) grow to a limited extent while 10′000 brewing yeast cells provide a direct measure of contaminant wild yeasts.
