A. BLA®EJ, I. ©PIDLA
Kvasny Prum. 1986; 32(11): 249-252 | DOI: 10.18832/kp1986069 
The presumption of biotechnology development inCzechoslovakiais the acquirement of raw-material basis. Current source of carbon for biotechnology i. e. main raw-material are saccharides - molasses, starch, saccharose. It will be necessary to revalue the possibilities of beet sugar utilization and accept measures in the production as well as in consumption. The better utilization alternative phytomass - lignocellulosic materials is retarded by economical and technical problems. The optimal solution of such problems in the presence is the production of medium and lowtonnage products of higher prince from phytomass hydrolysates in existing pulp and paper...

The sources of nitrogen, carbon, phosphor and others raw materials for biotechnological production.Peer-reviewed article
M. BUČKO
Kvasny Prum. 1986; 32(11): 255-258 | DOI: 10.18832/kp1986071
In biotechnological manufacturing, great numbers of basic conditions are required for the successful course of biosynthesis, which enable the increasing of production and makes manufactured preparations more economical. The use of suitable and at the same time inexpensive raw material is one of the most important conditions. Carbon and nitrogen sources, growth factors and inorganic substances are necessary in these all biotechnological productions. On the basis of enzyme system of producing microorganism, cornsteep liquor, soybean flour, peanut flour, rape meal, protein substrate hydrolyzates, yeast autolysate etc. are used as nitrogen sources, glucose,...
Microbial proteins.Peer-reviewed article
F. MACEK
Kvasny Prum. 1986; 32(11): 258-262 | DOI: 10.18832/kp1986072
A review about microbial proteins gives the fundamental approaches with technological and economical parameters of preparation of: a) microbial fodder proteins, both yeast and bacterial, produced from a variety of substrates, b) microbial food proteins, with possibility of utilizing all cell components. A short survey is presented of the possible utilization of waste microbial biomass. The economical feasibility of the process, availability, and price of raw materials, the demand for the product and its quality, affect to a major degree the realization of individual productions.(In Czech, English summary only)
Biotechnology aspect of organic acid production.Peer-reviewed article
R. J. KARKLIŇ©
Kvasny Prum. 1986; 32(11): 262-265 | DOI: 10.18832/kp1986073
Organic carboxylic acids as products of the microbial synthesis are described. Using chemical and physical mutagens active strains from genus Aspergillus for a production of citric and itaconic acids were selected. Testing various carbon sources the results proved a possibility to use molasses, liquid alkanes and hydrolysates of plant materials for acid productions. The procedures for isocitric and ketoglutaric acid as cell as for their salts production from liquid alkanes using the yeast Candida lipolytica were elaborated.(In Slovak, English summary only)
Preparation of amino acids by fermentation.Peer-reviewed article
J. PLACHÝ
Kvasny Prum. 1986; 32(11): 265-267 | DOI: 10.18832/kp1986074
The review deals with an application and a production of amino acids, especially with a preparation of amino acids by fermentation, from the point of view of producing strains, mechanisms of overproduction, source of carbon and an aeration. The production of amino acids inCzechoslovakiaand abroad is shortly characterized.(In Czech, English summary only)
Industry produced antibiotics - present condition.Peer-reviewed article

Biosynthesis and some properties of alpha-amylases from morphologically different forms of Bacillus subtilis R-623.Peer-reviewed article
A. A. GLEM®A, A. B. BAĄSIS, I. V. BACHMATOVA, L. A. BARATOVA, A. P. SINICYN
Kvasny Prum. 1986; 32(11): 269-273 | DOI: 10.18832/kp1986076
Homogeous preparations of extracellular alpha-amylases from cultural medium of P, R and S morphological forms of Bacillus subtilis R-623 were isolated by affinity precipitation followed by gel filtration and isoelectrical focusing. Some physico-chemical, immunochemical and catalytical properties of isolated a-amylases were studied. They have identical molecular weights, isoelectrical points and aminoacid compositions, yet are only morphological forms Bacillus subtilis R-623 are slightly different on theirs catalytical properties.(In Czech, English summary only)
