The article is focused on a measurement of kieselgur discharge in a small laboratory filter and on a verification of the filtration equation. The results were dependent on properties of the filtration bed. The highest discharge and reproducibility from the measurement with four different beds was obtained with textile tissue. The discharge of kieselgur was measured by the method with the ashored layer and by two methods with the gradual washing on of kieselgur under the constant pressure difference.(In Czech, English summary only)

The literature review on the application of malting germs is described. Malting germs are wastes from the malt production. The malting germs hydrolysis by alkaline protease was tested and the optimum conditions of the process were determined. It was proved that during hydrolysis about 65 % of raw protein is hydrolyzed very deeply. The hydrolyzed malting germs can he dried and powdered. The powder contains from 0.7 to 0.8 % of amino nitrogen and 35 % of extract. After the concentration the extract contains from 40 to 45 % of protein hydrolyzate (the degree of hydrolysis 38 to 42 %)' 40 % of dextrins and salts (to the extract dry weight). The amino acids...
A brief history of Saccharomyces sensu stricto.Peer-reviewed article

Kvasny Prum. 1991; 37(3): 74-79 | DOI: 10.18832/kp1991011
The authors briefly reconstructed the 150 year's history of classification of yeasts connected with wine and beer production known as the sensu stricto group of the genus Saccharomyces. Possible consequences of a correct or incorrect classification of these with wine and beer-associated yeasts which arise in relation with their use in the past, as well as at present or in the future, are elucidated from the point of view of importance for research and biotechnology.(In Slovak, English summary only)
