Studying the effect which the filtration of beer wort has upon the character of main fermentation and the quality of final product. i. e. beer, the authors have carried out a series of production-scale tests. They maintain that the filtration is important at breweries applying semicontinuous method of fermentation, since in this way the number of fermenting cycles can be almost doubled. As far as the composition of wort is concerned the changes caused by filtration are insignificant. On the other hand filtration speeds up the initial phases of main fermentation and permits to obtain pure yeast. Organoleptic tests failed to find any difference between...

Projected and achal capacities of breweries.Peer-reviewed article

J. LOOS

Kvasny Prum. 1965; 11(7): 153-155 | DOI: 10.18832/kp1965021  

The problem connected with the maximum possible ulization of machinery and installations at breweries are discussed very often and the opinions are sometimes controversial. The article deals with te actual production capacity of new breweries as compared with their projected parameters. The author analyses the curves of beer production in individual months, calculates the highest possible limits and underlines an economical interdependence between the theoretical capacity and actual production. The situation in new breweries should be seen from this point of view and figures from projects carefully compared with actual ones.(In Czech, English summary...

Adaptability of the Candida strains to recirculated molasses mash and semicontinuous cultivation.Peer-reviewed article

A. ČEJKOVÁ

Kvasny Prum. 1965; 11(7): 155-159 | DOI: 10.18832/kp1965022  

Five strains of the Candida yeast family have been tested to study their behavior in the new process known as molasses mash recirculation [the process has been recently patented in Czechoslovakia]. Recirculation of mash slows down the propagation speed. From five strains selected for comparison Candida utilis var. maior 156 was affected far less than other. The drop in the yield of biologic substance was observed only when the mash density exceeded certain limits. Four other strains failed under the described conditions to five satisfactory results.(In Czech, English summary only)
