Biological Activity of Ag and Cu Monometallic Nanoparticles and Ag-Cu Bimetallic Nanocomposites against Plant Pathogens and Seeds

Tinatin DOOLOTKELDİEVA | Saykal BOBUŞOVA

The antibacterial activities of silver (Ag) and copper (Cu) monometallic and bimetallic nanoparticles (MNPs and BNPs) against the most economically important and common plant bacterial diseases in Kyrgyzstan were tested, as well as their phytotoxic effects on wheat and corn seeds. To achieve this, a range of Ag and Cu MNPs and BNPs were synthesized using different methods and were tested at different concentrations to compare their biological effects. The antibacterial activities of Ag and Cu MNPs and Ag-Cu BNPs against the plant pathogenic bacteria Erwinia amylovora, Pseudomonas syringae, and ...Более

Microbial communities of vegetable seeds and biocontrol microbes for seed treatment

Tinatin DOOLOTKELDİEVA | Saykal BOBUŞOVA

Thirty-one species of vegetable seeds from Kyrgyzstan's State Register were analysed for mycological and bacterial composition using various methods, from simple visual to molecular. The modified roll-towel method simultaneously assesses the degree of contamination and seed germination. Screening in agar medium allows analysis of species on the outer and inner surfaces of vegetable seeds that are not detected using the roll-towel method. As a result of the phytopathological examination, 15 fungal and three bacterial species were found. Direct DNA extraction and amplification of the universal 1 ...Более

LOW TEMPERATURE AND VEGETATION EFFECTS ON THE SOIL BACTERIAL COMMUNITIES STRUCTURE IN HIGH MOUNTAINOUS AND COLD BIOTOPES IN KYRGYZSTAN

Tinatin DOOLOTKELDİEVA | Saykal BOBUŞOVA

It is well known that soil microorganisms play essential roles in the biogeochemical cycling of biogenic elements and soil-forming processes. However, little is known about the effect of the vegetation type on the bacterial community structures in soils from cold regions. For these reasons, we have analysed the bacterial communities of eight biotopes covered with different plants and two biotopes without vegetation in the Son-Kull Valley as the coldest corner in Kyrgyzstan. Using the culture-depended and culture-independent (16S rRNA gene sequencing) methods, we found 4 phylum (Actinobacteria- ...Более
