Exopolysaccharides of lactic acid bacteria as protective agents against bacterial and viral plant pathogens.

In this study, 25 exopolysaccharides produced by lactic acid bacteria (LAB) were screened for their effect on plant pathogens. The molecular masses of EPS were found to be 3,8-5,0 × 10 Da. The GC-MS analysis revealed that EPSs were majorly composed of glucose (85.

Effect of on the metabolites accumulation in chicory and lettuce plants cultivated .

The influence of the culture medium without bacterial cells, obtained after the cultivation of endophytic bacteria UCM B-5715, on the growth and synthesis of some metabolites in lettuce and chicory seedlings under conditions was studied. Bacteria were cultivated in liquid LB medium at 37 ºC for 24 h with periodic stirring. The culture fluid was separated from the cell biomass.

Chromogenicity of aerobic spore-forming bacteria of the Bacillaceae family isolated from different ecological niches and physiographic zones.

To determine the distribution patterns of pigmented bacteria of the Bacilaceae family in different physiographic zones and ecological niches, we recovered 787 isolates from 185 environmental samples (including the areas with radiation pollution). Among the strains obtained, 149 pigmented representatives were detected, which synthesized intracellular and extracellular pigments of yellow, red, pink, and dark colors. In compliance with physiological, biochemical, and chemotaxonomic features, the isolates were identified as 7 species of the Bacilaceae family.

Genetic, Epigenetic and Phenotypic Diversity of Four Strains Used for Plant Protection or as Probiotics.

strains are applied as ecologically safe biopesticides, plant growth promoting rhizobacteria (PGPR), and in veterinary probiotics. They are abundant in various environments including soil, plants, marine habitats, the intestinal micro-flora, etc. The mechanisms underlying this adaptive plasticity and bioactivity are not well understood, nor is it clear why several strains outperform other same species isolates by their bioactivities.

ENERGY PROFILE OF RATS WITH OVERACTIVE BLADDER SYNDROME PHARMACOLOGICALLY CORRECTED WITH QUERCETIN.

We studied the effect of Quercetin on energy profile of erythrocytes of rats with the overactive bladder syndrome. It was shown that animal models with the subject pathology demonstrated alteration of quantitative composition of the adenine nucleotide system in erythrocytes. Abrupt decrease of the total concentration of adenyl nucleotides and ATP compared to the intact group of animals was noted in the study.

Study of artemisinin and sugar accumulation in Artemisia vulgaris and Artemisia dracunculus "hairy" root cultures.

We studied the effect of genetic transformation on biologically active compound (artemisinin and its co-products (ART) as well as sugars) accumulation in Artemisia vulgaris and Artemisia dracunculus "hairy" root cultures. Glucose, fructose, sucrose, and mannitol were accumulated in A. vulgaris and A.

Fundamental Basis of Creation of Probiotic with Provitamin Activity Based on Strains Bacillus amyloliquefaciens IMV В-7513 and IMV B-7525.

Dysbiotic conditions prevail in both humans and animals. Intestinal dysbiosis is accompanied, in addition to the quantitative and qualitative changes of the microflora, by immunosuppression and metabolic disorders, such as avitaminosis А. Therefore, the search and study of microorganism strains, which may be used for correction of dysbiosis and allow to normalize the homeostasis of a macroorganism, are highly relevant today.

[The Decomposition of Various Types of Crop Residues by Strains Bacillus subtilis IMB B-7516 and B. licheniformis IMB B-7515].

It is shown that Bacillus subtilis IMB B-7516 and B. licheniformis IMB B-7515 strains are capable to decomposing crop residues. The effectiveness of the wheat straw decomposition by both strains was 15 - 30 %, sunflower and corn stubble - 40 - 60 % under the laboratory conditions.

[Resistance of microorganisms of coastal ecosystems of the Dead Sea to extremal factors].

Such extreme factors as UV radiation, high temperature and salinity, and also the small amount of accessible water have an influence on microorganisms of coastal ecosystems of the Dead Sea. Resistance to these factors of the microorganisms isolated from ecosystems of this region (vertical steep gorge around the Dead Sea, clay-salt plain and black highly mineralized muds) is studied. Aerobic, chemoorganotrophic, thermotolerant, moderately halophilic bacteria which, according to their morphological and physiological properties, are similar to species Gracilibacillus halotolerans, Salimicrobium album and genus Caryophanon have been isolated from these ecosystems.

[Influence of lactitol and lactulose on adhesion properties of Bacillus subtilis probiotic strains].

Adhesion properties of probiotic strains Bacillus subtilis UKM 5139 and Bacillus subtilis UKM 5140 is studied. It is shown that the strain Bacillus subtilis UKM 5139 is nonadhesive, and the strain Bacillus subtilis UKM 5140 is subadhesive. Lactitol and lactulosa did not influence the adhesive properties of probiotic strains of bacilli, and reduced these properties of conditionally pathogenic microorganisms.

[Prebiotic properties of lactite and lactulose under creation of synbiotics of bacillus genus bacteria].

The influence of lactite and lactulose on growth of probiotic strains B. subtilis UKM 5139 and B. subtilis UKM 5140 and conditionally pathogenic microorganisms has been studied.

[Growth peculiarities of probiotic strains of Bacillus subtilis at their joint cultivation in deep conditions].

Growth peculiarities of probiotic strains B. subtilis UKM 5139 and B. subtilis UKM 5140 have been studied at their joint cultivation in deep conditions.

[Effect of culture media pH on biosynthesis of hydrolytic enzymes in bacilli].

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.
