The taxonomic position and biological activities of two Bacillus strains used in veterinary probiotics were studied in this work. These microorganisms inhibit growth of a broad spectrum of pathogenic cultures. They synthesize proteolytic enzymes and other biologically active metabolites, and to some extent, supplement each other with probiotic activities.(More)
Different trace elements in the composition of nine synthesized complex compounds of N-oxides of pyridine derivatives have been studied. It has been shown that the effect of trace elements included in the composition of nutrient media on accumulation of cells and exopolysaccharides (EPS) by the strains of B. subtilis is sufficiently expressed; it is also(More)
Preparations of alpha-amylase have been obtained as a result of screening of Bacillus subtilis strains. They can hydrolyse starch at a temperature from 60 to 95 degrees C at acidic and alkaline values of pH and hold stability during 2-3 hours. Alpha-Amylase of B. subtilis 147 with optimum pH 9.1 which displayed activity at 95 degrees C, proved to be(More)
The paper deals with lytic activity of 226 strains belonging to 13 species of Bacillus genus, isolated from various econiches, in respect of the cells of Staphylococcus aureus, Escherichia coli and Candida albicans as representatives of Gram-positive, Gram-negative and yeast groups of microorganisms. All the studied strains of bacilli displayed lytic(More)
The effect of pH value of cultivation medium on biosynthesis by bacteria of Bacillus genus of different types of hydrolases has been studied. The optimum pH medium values for each of the studied enzymes were chosen that allowed to increase the activity of produced xylanases and lypases--1.3-1.5 times, endoglucanases--4-5 times, cellobiases--18-20 times and(More)
A wide range of carbohydrate sources for the growth of industrial Bacillus subtilis strains were studied. The growth was mainly accelerated 2.7 and 2.5-fold by adding green syrup and glucose in a combination with xylose, respectively, in comparison to the traditional glucose. The revealed nutritional demands of these bacteria allowed us to select an optimal(More)
The dynamics of accumulation of Bacillus subtilis 39 cells and spores under different conditions of aeration has been studied. It is shown possible to intensify the process of growth, biomass accumulation and sporulation of bacteria using aeration conditions. The growth of cells of the studied bacilli proceeds under conditions of providing the culture with(More)
The paper on the occasion of the 80th anniversary of the D.K. Zabolotny Institute of Microbiology and Virology at the National Academy of Sciences of Ukraine is dedicated to the research activity of one of its oldest subdivision--the Department ofAntibiotics. The basic trends of scientific researches and their most important results for the whole period of(More)
The authors conducted the study on efficiency of Subalin medication for treatment children with chronic virus hepatitis. The use of improved curative complex including Subalin medication enables the regression of clinical signs of the disease, allows decreasing the signs of intoxication which alleviates the state of the children. Treatment with Subalin(More)
