The selective media found useful in the examination of sugar products are: (a) Osmophilic medium , consisting of a synthetic wort agar made in a 45° Brix, partially inverted syrup, for the examination of osmophilic yeasts. (b) A modified Sabaroud's broth for the estimation of yeasts on membrane filters. (c) Dextrose tryptone agar, liver broth and iron sulphite agar for thermophils. in the third medium reduced sulphite concentration would probably be more accurate in the estimation of Cl. nigrificans. There is no satisfactory selective medium for capsulated bacteria in sugar products.
