The article deals with a microbiologic method which has been developed for the evaluation of the efficiency of synthetic desthiobiotin used for making baker's yeast. Experiments have carried out with baker's yeast in synthetic medium and it has been that synthetic desthiobiotin is a very good precursor of biotin. Its efficiency as compared with biotin is as high as 50%.(In Czech, English summary only)

Two sorts of dark-skinned grapes were used to make on an experimental scale red wine in carbon dioxide atmosphere. The product was very fine, heavy-bodied, bright red wine of good taste and bouquet. The method has certain disadvantages, viz.: longer technological process and lower yield. The yield can be improved by using approprietly designed presses. The principal advantages are on the other hand reduced requirements to sulphitation and absence of difficulties connected with submerging the swimming pomace cap and controlling the must against excessive heat generation. It is therefore possible to make fine red wine without removing stems and without...
