Abstract

The selective media found useful in the examination of sugar products are:

(a) Osmophilic medium, consisting of a synthetic wort agar made in a 45Β° 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.

Images are presented which show that NMR microscopy can be used to determine the spatial distribution of sugars in grapes. The production of appreciable sugar gradients during the final ripening process was detected in parenchymatous tissues around the seeds, but these gradients disappeared in fully
