Suitable physico-chemical properties of silicious sol Tosil P determine its wide use in brewing technology. The effect of the application of this preparate on the procedure of principal fermentation and following filtration of beer was studied. The results from plant-scale experiments proved a higher rate of the fermentation process in presence of colloidal silica. From this standpoint the optimum dosage of Tosil P from 75 to 100 g. hl-1 before the hopped wort inoculation was found. The addition of Tosil P has a positive effect also on the beer filtration - the pressure increase during filtration and final clarity of beer. The worse beer...

The description of changes in volatile compounds and diacetyl during 20 fermentations performed in two conical bottom fermenting vessels in Brewery Bratislava is made in the article. There is practically no difference in the quality of volatile compounds in beers produced with this procedure and with classical one. The differences were observed in the higher levels of alcohol and carbon dioxide and the lower level of residual extract in beers from conical bottom fermenting vessels.(In Slovak, English summary only)

A comparison of beers produced with the same yeast strain but using one-stage and classical fermentation procedures was performed. The results showed that both the technologies gave beers with similar physico-chemical and sensorial properties of the yeast strains the proper selection of the suitable strain is necessary when the one-stage fermentation process is used.(In Czech, English summary only)

A mutant of Corynebacterium glutamicum 9366-AEC/100, resistant to lysine analogue and dependent to homoserine has been isolated. The mutant is capable to produce 60 g . l-1 lysine after 60h of cultivation at a converse rate 28 %. There is possible to obtain both technical and crystallic lysine with purity 35, resp. 95 %.(In Czech, English summary only)

An optimization of the degradation of yeast cell walls using self lytic system of the yeasts with the aim to the yeast fractionation was developed. Autolysis in 10 % suspension of the baker's yeast, initiated with the addition of previous autolysate, is finished in 24 h under conditions of mixing and the temperature of50 °C. The process can be intensified by the addition of ethanol and NaCl. Under these conditions the minimum of 70 % of proteins is released from the yeast cells in 24 h.(In Slovak, English summary only)
Prospects of SCP production.Peer-reviewed article

On a base of the proposed development and production of classical fodder proteins (soya, fish flour) the prospects of SCP production are evaluated from the standpoint of the utilization of various substrates and the optimization of technological procedures. Also technological innovations are taken into account with respect to the possible decrease of investment and production costs.(In Czech, English summary only)
