Long term development trends in Czechoslovak Brewing Industry.Peer-reviewed article
J. KURZ, V. KOPECKÝ
Kvasny Prum. 1976; 22(1): 3-6 | DOI: 10.18832/kp1976001 
The article deals with a number of selected indices covering a long period of time and reflecting character and pace of changes in beer consumption Czechoslovakia, structure of production and development of brewing capacities. Among the parameters included into the study are consumption of beer per capitum, peak consumption in summer months, shares of bottled and cask beer, shares of various sorts differing by strength and colour, share of export, average production per one brewery, equipment of storage cellars and coefficient of its utilization.(In Czech, English summary only)
Bacteria contaminating the products of brewing industry.Peer-reviewed article
O. BENDOVÁ
Kvasny Prum. 1976; 22(1): 10-13 | DOI: 10.18832/kp1976002
The authoress specifies principal groups of bacteria contaminating beer and its semi products, outlines their properties, their taxonomic classification and its changes. The article covers all important kinds, i.e. lactic acid bacteria [Lactobacilli and Pediococci], acetic acid bacteria and wort bacteria. To make the survey complete the Zymomonas kind and its species are described, too, though so far they can be found only in British beer produced through top fermentation.(In Czech, English summary only)
Application of tetracykline for suppression of bacterial contamination of yeast during its determination process.Peer-reviewed article

The committee of brewing industry for yeast and microbiology recommends to use tetracycline whenever determining yeast, since it can efficiently suppress bacterial contamination. In a proper concentration, i.e. 30-50 µg per one mi tetracycline prevents propagation of bacteria in wort and sweet wort agar media without affecting yeast growth. Very good results have been achieved also in cultivation of microorganisms on membrane filters. Even in the 100 µg/ml concentration tetracycline does not reduce the number of yeast colonies when pure culture stems [ Saccharomyces carlsbergensis] as well as other stems of yeast are being inoculated.(In...
Utilization of hydrolysates of lignocelluloses materials in fermentation industry.Peer-reviewed article
J. FORSTHOFFER
Kvasny Prum. 1976; 22(1): 16-17 | DOI: 10.18832/kp1976004
The article deals with a number of various methods which can be used to prepare hydrolysates from lignocelluloses materials and then utilize them as unconventional raw material in fermentation industry.(In Czech, English summary only)
