The article deals with new methods which have been developed to classify the quality of barley and mat better than methods so far used. New methods are based on research works of Chapon, Kretschmer, Hartong and Narziss. The authors maintain that the most reliable criteria are those calculated from several analytic attributes which are related to one another and express one of the quality factors. New methods applied do Czechoslovak brewing barley and malt confirm their excellent quality ensuring them exceptional position in Europe.(In Czech, English summary only)

The new medium is essentially a modification of the well know Nakagawa medium. It can be easily prepared in any laboratory and does not require cultivation under anaerobic conditions. Casein hydrolysate "Sevac" can be used as a suitable growth - regulating substance. The temperature during the cultivation period...
