The export of malt is a specific task for a branch of beer production. To evaluate the effectivity of this export a comparison of a fodder corn production and of a brewing barley production has to be made. The final solution of this problem results in a condition of an achievement of the minimum advantageous export price of malt. The condition of this price depends on productivity costs. Further restriction of a suitability of the malt export is on a degree of a rentability of means invested. The export price of malt is also resticted by the mean price level in the world. The results of this consideration is to determine the range of malt export prices...

In the first part of this study (1) a simplified mathematical model of a continuous culture of the yeast Candida utilis on synthetic ethanol was described. The effect of oxygen concentration in an aeration gas on the specific production was observed. The results obtained served to an estimation of a volume of the fermenter which was necessary to achieve the desired capacity. In the second part of the article economic consequences of the effect of different oxygen concentrations in an aeration medium during yeast cultivation on synthetic ethanol are discussed.(In Czech, English summary only)
Inlet, interstage and outlet inspection in a production of non-alcoholic beverages.Peer-reviewed article

The principles of inlet, interstage and outlet inspection in a production of non-alcoholic beverages are described. It is necessary to equipped laboratories in our factories by instruments which enables the inspection o beverages in a range mentioned in the lecture. The following instruments must be installed in every laboratory: pH meter, automatic titrators, polarographs, tubidimeter, oximeter, and an apparatus for metal estimations.(In Slovak, English summary only)
Two-stage continuous biosynthesis of L-lysine.Peer-reviewed article

The conditions of the L-lysine continuous biosynthesis was studied using the suppressor mutant Brevibacterium sp. CCM AO 6/79. In contrast with literature data (multi-stag continuous systems the production process was simplified maintaining the optimal conditions of amino acid biosynthesis. The highest yields were achieved using the two-stage continuous culture with the semicontinuous regime in the second stage. When compared with batch culture the production of L-lysine was increased roughly by 70 %.(In Czech, English summary only)
Filtration of diluted suspensions.Peer-reviewed article

A procedure for the estimation of the quantity of a solid phase dispersed in a liquid using a method of pressure filtration is described. The quantity of solid phase in a suspension is determined from courses of filtration straight lines obtained with the two diluted suspensions and from determination of the suspension density and the density of the liquid phase only using a pycnometric method.(In Czech, English summary only)
