The article describes the role of sulphur dioxide in beer, being active as an antioxidant, an antimicrobial substance or a substance disguising stale beer flavour. There have been described its forms of occurrence in beer, concentrations commonly occurring in beer, including legislative restrictions. The article also describes the mechanism of its formation during fermentation as well as the factors influencing the mechanism and its decrease during storage.The article describes the role of sulphur dioxide in beer, being active as an antioxidant, an antimicrobial substance or a substance disguising stale beer flavour.

Germination of grains of the spring barley varieties Jersey and Tolar was monitored under laboratory conditions simulating static malting. The samples used were steeped in such a way, to contain 45% of water after 72 hours of test duration. The total time of steeping and germination was 6 days. The samples were put in glass bottles closed with a rubber membrane. Always before grain weighing and further handling with the samples, 2 ml of the gas among grains were sampled by means of a tuberculin syringe. During the test, the gas composition in the bottles was purposefully influenced by ethylene and carbon dioxide sorbents and, to the contrary, an environment...

Field trial in which we observed the influence of decayed waste on spring barley yield and quality was founded University farming business in Kolíňany in 2004-2005. The highest average grain yield and biological yield (phytomass dry mater) were reached with spring decayed waste application (6,14 t.ha-1, resp. 12,56 t.ha-1). The lowest values of gross protein provided "Manure 25 t.ha-1" variant (9,0%) in average of 2004-2005 and in 2005 variant with application of 50 t.ha-1 of decayed waste (10,4%).Field trial in which we observed the influence of decayed waste on spring barley yield and quality was founded University farming business in Kolíňany in...

The personal opinions and beliefs, and therefore decisions about whether mankind activities are sustainable or non-sustainable depend both on one's knowledge and irrational arguments. In this series, my contributions aimed at offering some rough insights into processes vital to man9s future. Many recent publications deal with sustainability in great detail. The Millennium Ecosystem Assessment as well as the book entitled "The Revenge of Gaia" by J. Lovelock are briefly introduced. Contrary to these pessimistic reviews, readers are also directed to the extremely optimistic assessment of the recent development of human societies presented in the book...
