Actidione HiVeg™ Agar w/ Actidione® is recommended for the enumeration of bacteria in specimens containing large numbers of yeasts and moulds.The medium is used for microbiological investigation during brewing and baking. Actidione (Cycloheximide) at a concentration of 0.001% permits the growth of bacteria and inhibits the growth of most yeasts and moulds except dermatophytes. This medium may be used for the estimation of bacterial contamination of pitching yeast. Addition of penicillin or streptomycin may be used for selective isolation of dermatophytes. Actidione HiVeg™ Agar w/ Actidione® is prepared by using vegetable peptones in place of animal based peptones which make the media free of BSE/TSE risks.
