With increasing production and export of bottled beer it is necessary to achieve higher stability of beer. Qualitative signs which rescribes the stability are the clarity, taste, flavour colour and foaming power. The article describes chemical composition of compounds which form chill haze - protein, polyphenols, saccharides and mineral compounds. Theories of the formation of chill haze and possibilities for an achievement of higher beer stability are discussed. The compounds used as stabilizers are divided into groups according to the action of their own. Several examples obtained from experiments carried out on different scales with adsorbents of...

Basic equations for the calculation the inactivation of microorganisms during pasteurization of beer and beverages are shown. According to classic conception, the thermal resistance of microorganisms in described by the values of D and z in food industry while the symbols of E and D are used in bioengineering. The values of D and z for various microorganisms and examples of the calculation are given in the article.(In Czech, English summary only)

The effect of oxygen supply on the changes in total and specific rate of oxygen consumption by cells, oxygen transfer rate, saturation concentration of dissolved oxygen and the yields of batch and continuous cultivation was studied. The microorganism used was Klebsiella aerogenes CCM 2318 growing in synthetic glucose medium. Continuous cultures were carried out at dilution rates of 0.96 and 0.178 h-1. The rate of oxygen transfer was determined by the sulphite methods and the coefficient KLa was assessed using the dynamic method with a correction for changes in the saturation of dissolved oxygen. A decreased oxygen supply...
