The article deals with the technique elaborated for the partition of malt proteins by means of polyacrylamidegel disc electrophoresis. The samples of beer and wort were first concentrated through lyophilization. The partition technique did not practically differ from that applied by Cebecauer for the partition of blood serum proteins [ tris-glycine buffer, 10-B amide red as dyeing agent]. The proportion of monomer concentrate to structure-forming agent determining the porosity of the carrier was also the same as in Cebecaurers experiments. The partition takes place in the colums of dense gel [7% of acryl-amide, 0,17% of structure-forming agent, pH...

Kvasny Prum. 1971; 17(5): 107-109 | DOI: 10.18832/kp1971019
The article deals briefly with modern fermentation and post-fermentation methods and new types of fermentation plants which have been recently developed. The following types are described and evaluated: large-capacity tanks standing free on open places, tanks for pressure fermentation, combined large-capacity tanks, vertical tanks with tapered bottoms and plants for two-stage fermentation. Taking into account conditions prevailing inCzechoslovakia, the authors recommend vertical and free standing tanks. Such tanks reduce costs and ensure good quality of beer. To shorten time required for post-fermentation two-stage system should be given preference.(In...
