An estimation of the difference between flour and grist with mills of Miag (25 %), Casella and DLFU is described. The types of mills are described together with the roughness of grinding estimated with Pfungstadt screen. The difference of flour grist is estimated with all the types of mills with various modifications of malts. The deviation among the individual mills is calculated. The results obtained with the DLFU m ill are evaluated for the description of malt modification.(In Czech, English summary only)

Killer-toxins (zymocins) are proteins produces by killer strains of yeasts and yeast-like organisms. An ability to produce a killer toxin and resistance to it (i. e. the killer-character) are determined by doublestranded RNA and only rarely by DNA. The killer-toxins kill sensitive strains of yeasts. A molecular mechanism of killer-toxin action and expression of the killer-character have been already determined in several canes. Transfer of the killer character among yeast cells is possible by means of sexual hybridization, induced protoplast fusion or cytoduction. Killer yeasts can be cured of their killer character. A new method of selection, polyploidization...

Based on long-term investigations on the yeast flora of wines with residual sugar the occurrence of Zygosaccharomyces bailii in bottled wines could be confirmed. Causes of occurrence and possible localities in the wineries and suitable measures for the elimination of these yeasts are shortly discussed(In Slovak, English summary only)
L-lysine biosynthesis with the strain Corynebacterium glutamicum 10-20/60. Non-standard nitrogen sources.Peer-reviewed article

The production strain Corynebacterium glutamicum 10-20/60 produces from 36 to44 g of L-lysine per1 liter of the medium containing saccharose and non-standard nitrogen sources such as are hydrolysates of rate, flax and cotton-plant grists. If acetic acid as the carbon source is used the production from 22 to30 g of lysine per liter of the medium is achieved. Experiments on the laboratory scale were performed in flacks on a rotary shaker at29 °C for 96 hour of fermentation.(In Czech, English summary only)
