Serological method of distinguishing culture and wild yeasts.Peer-reviewed article

A. KOCKOVÁ-KRATOCHVÍLOVÁ, J. ŠANDULA

Kvasny Prum. 1963; 9(8): 181-186 | DOI: 10.18832/kp1963032  

The authors describe practical application of a serological precipitation method based on a two-stage diffusion in agar-agar gel for ascertaining the differences between culture and wild yeasts. Some specific features characterizing various strains of Saccharomyces carlsbergensis in sensu strict as well as strains of stems fermenting both maltose and saccharose are discussed in detail. The suggested method can be further perfected by employing sera saturated with affine sorts.(In Czech, English summary only)

Economical water consumption in pneumatic malting plants.Peer-reviewed article

A. DOLEŽALOVÁ, M. NENTWICHOVÁ, J. VLČEK

Kvasny Prum. 1963; 9(8): 188-191 | DOI: 10.18832/kp1963033  

Starting from theoretical base the authors discuss in a comprehensible, popular form principal problems concerning operation of installations serving pneumatic malting plants employing the shifting heap technique. Important questions, as the mechanism of heat generation at exotermical reactions consuming starch and fat through aspiration, role of heat at the formation of new substances etc. are discussed in detail.(In Czech, English summary only)

Research work on manufacturing food yeasts by continuous fermentation and practical application of this method.Peer-reviewed article

Starting from detailed calculations the authors have developed an efficient method of making food yeasts by continuous fermentation. The technology has several definite advantages. Its cycle lasts 3 weeks and apparently could be extended to 4 weeks. The existing equipment of the yeast plant atTeplicecan be employed without any substantial investments. The production is based on processing various wastes which are now disposed of without any use, as e. g. waste liquor at plants making citric acid, waste water at gas works etc. One important question has yet to be solved i. e. purification of waste water at the yeast plant itself.(In Czech, English...
