To provide the workers of brewing and malting industries with comprehensive information on microorganisms important in their branches the author presents a survey of malt and barley microflora. His contribution is very useful, since at present no realiable data could be found in available literature. The present part of the work deals with the problems of contamination, with field microflora and its classification. Abstracts from works published in various countries are arranged in chronologic order and cover both technologic and hygienic aspects, as well as effects microflora has on the quality of final products.(In Czech, English summary only)

The article deals with the range of problems which can be resolved in the laboratory of a brewery by using a Hewlett Packard HP 97 calculator. The authors present programs for evaluating refractometric and distillation analyses of beer as well as its quality. Data processing saves much time of laboratory workers and reduces considerably occurance of errors. Other fields of application are: analyses of barley, evaluation of barley and malt quality, evaluation of pasteurization efficiency, analyses of statistics data, specification of consumption norms, calculation of extracts yields tec.(In Czech, English summary only)
Effects of bioengineering factors upon the formation of secondary metabolic products.Peer-reviewed article

Conditions which must be created in industrial fermentation plants to ensure cultivation of mycelial microorganisms producing antibiotics differ substantially from those typical for conventional fermentation process. The article deals with the growth of mycelial suspensions, their hydrodynamic behaviour and with the effects of oxygen supply as well as design of fermenters and agitators upon the formation of secondary metabolic products.(In Czech, English summary only)
Application of ultra filters as enzymatic reactors for extracting pectins from solutions.Peer-reviewed article

The results of a series of experiments carried out with various solutions containing pectin confirm, that an ultra filter can be used as a reactor in pectolysis processes. The sefficiency of pectolysis is higher, less enzymes are required and solutions are sterilized. For final evaluation the method will be applied to fruit juices.(In Slovak, English summary only)
