A procedure and conditions for the determination of the volume of conical bottom fermenting vessels for the single-tank beer production are described in the article. Examples of the necessary capacity are given with respect to a building of new factories and an enlargement of contemporary capacities. The following formula was derived for the calculation: MKCKT = Si where MKCKT is the monthly capacity of the complex of CKT, i is the number of types of beer, ks is the coefficient of a composition of products, Op is the liquid volume of the vessel, p is the number of vessels, z0 is the...
Importance of selected wine technology 1st part: Role and position of wine yeast cultures in Czechoslovak wine technology.Peer-reviewed article

Kvasny Prum. 1984; 30(8): 173-176 | DOI: 10.18832/kp1984031
The introductory part of this work presents information on the utilization of the Yeast Collection of the Research Institute for viticulture and Enology in Bratislava and on the production of liquid yeast starters. Selected wine yeasts strains used in Czechoslovak wine industry are briefly characterized. Problems of pure wine yeast starter propagation, preparation of active dry wine yeasts and their application in enological practice are discussed.(In Slovak, English summary only)

Pectinase complexes of commercial preparations Pectinex Ultra (Schweizerische Ferment AG, Basel) and Leozym (Slovlik, n. p., Leopoldov, Czechoslovakia) containing endopolygalacturonase, exopolygalacturonase, pectin, lyase, and pectinesterase were irreversibly immobilized by adsorption on polyethyleneterephthalate - orsilen )Silona, n. p. Planá nad Lužnicí, Czechoslovakia) in0.1 Macetate buffer, pH 4.2. The immobilization resulted in a lowering of pectinolytic activity; the measure of the lowering depended on the amount of the enzyme fixed on the carrier. The highest relative pectinolytic activity (28.1 % Pectinex Ultra, 18 % Leozym) had the preparations...
Determination of oxygen transfer coefficient with the correction for the actual cultivation conditions.Peer-reviewed article

Kvasny Prum. 1984; 30(8): 182-187 | DOI: 10.18832/kp1984033
A method for determination of the volumetric oxygen transfer coefficient KLa from dynamic measurement data under conditions of both excess oxygen and oxygen limited growth of microorganisms is described. The KLa determination follows from the integrated form of the oxygen balance equation and involves a correction for the actual cultivation conditions during measurement. In addition, the method is verified by its application to cultivation data.(In Czech, English summary only)
