The article deals with the results of experiments aimed at increasing the germinating ability of barley in the stage of afterharvest ripening. For this purpose an effective treatment has been developed improving the permeability of grain hull to oxygen, which is vital for accelerated ripening. By combining the favourable effect of acid ammonium fluoride, aeration, spraying and drying, a new technology has been developed securing full germination of all the barley varieties requiring long dormancy. With barley of the 1960 harvest normal germination was observed in the fourth week of the ripening period, i. e. three weeks after the harvest. The treatment...
Mycelium developing forms of torulopsis utilis. (Candida utilis).Peer-reviewed article

The article specifies conditions, under which yeast fungi of Torulopsis utilis group acquire new property, i. e. power to develop pseudomycelium. It has been stated, that the stem in question acquired the mentioned capacity through adaption to medium consisting of waste liquors after citric fermentation. Stems without such an adaptation can hardly acquire the mycelium developing power. The results of large scale experiments are presented in the form of tables.(In Czech, English summary only)
New microbiological testing methods in food industry.Peer-reviewed article
M. TEPLÝ
Kvasny Prum. 1961; 7(8): 183-187 | DOI: 10.18832/kp1961028
The article deals with new microbiological testing methods, which have been developed for application in food industry. The technology of preparing the so called MICROBITESTS and the range of their applications is described. The term MICROBITEST is used for special indicating papers soaked with nutritive substances, some of which may have selective character. The microorganisms present in the liquid to be tested are absorbed into the surface layers of the paper and develop there after the incubation period into colonies. If a suitable indicator is present in the paper, the reaction will take place with the products of biologic activity of microbes...
