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.

Inhibition of heat-induced protein aggregation by zirconium phthalocyanines.

Specific proteins found in food sources tend to aggregate into fibrils under heat treatment; studying these aggregation processes and developing tools to control protein heat-induced aggregation is an active area of research. Phthalocyanine complexes are known to exhibit antiprionic and anti-fibrillogenic activity. Thus, the anti-fibrillogenic effect of a series of Zr phthalocyanines with different out-of-plane coordinated ligands, namely positively charged (PcZrLys ), negatively charged (PcZrCitr ), and group able to form disulfide bridges (PcZrS ), on the heat-induced aggregation of such proteins as BLG, insulin, and lysozyme was studied.

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.

Analysis of the motion of vacuolar volutin granules in Saccharomyces cerevisiae.

The moving volutin (polyphosphate) granules known as "dancing bodies" can be observed in the vacuoles of the yeast cells. The aim of work was to study the effects of cultivation conditions and influences of physico-chemical factors on the motion of vacuolar volutin granules in Saccharomyces cerevisiae cells. The motion of granules is a non-Markovian process.

[PROPERTIES OF SACCHAROMYCES CEREVISIAE VOLUTIN GRANULES UNDER CONDITIONS OF THE CHANGE OF SPACE WEATHER].

In this work, the impact of space weather on the staining and the motility of volutin granules ("dancing bodies") in vacuoles of yeast Saccharoniyces cerevisiae with normal and changed phosphoric metabolism was studied. It was showed that the installed ear- lier relation between metachromatic reaction of volutin granules and galactic cosmic rays was confirmed by DAPI-staining of inorganic polyphosphates in cells S. cerevisiae UCM Y-517.
