Microbial communities associated with the plant rhizosphere play an important role in carbon sequestration, regulation of nutrient cycling, and the efficient functioning of the ecosystem as a whole. The diversity of microorganisms inhabiting the plant rhizosphere and their complex interactions with the host plant significantly affect the morphology, physiology, growth, development, and health of plants. At the same time, it is known that the soil microbiome diversity is affected by the type of soil, the type of cu...

Today there is a serious environmental problem - global climate change, and one of the main reasons for this change is the release of so-called greenhouse gases, and primarily raw carbon dioxide. One strategy to reduce the concentration of carbon dioxide in the atmosphere is to capture carbon dioxide from industrial emissions, since this is where the gas is found in high concentrations. In addition to physical and chemical methods, carbon dioxide capture is possible with the help of biological methods, for example...

Global climate change is one of the most acute environmental problems of our time. Among the methods of capturing CO2 in industrial emissions are chemical, physical and biological. The latter are based on the use of living organisms that absorb carbon dioxide in metabolic processes, and the subsequent use or burial of their biomass or their metabolic products. One variant of organisms used to capture carbon dioxide biotechnologically are microalgae. In the present study, the efficiency to capture carbon from the e...

Surfactants as detergents and emulsifying agents are used in various fields of industry and agriculture. These amphiphilic compounds contain hydrophobic and hydrophilic fragments and are usually produced by large-scale chemical synthesis processes. However, recently there is a request to develop biotechnological methods to obtain surfactants, since biosurfactants have many advantages above their chemical analogues - higher tolerance to extreme temperatures, pH and salinity, higher stability and lower or zero negat...

Biosurfactants produced by soil microorganisms are now widely used in various industries and are able to compete with synthetic detergents. However, in contrast with chemical surfactants, biological ones have disadvantage: it is difficult to obtain the product of high purity since the microbes usually produce a complex mixture of compounds, besides the cultural medium itself contains a lot of various components. Thus, the conventional scheme of lipopeptide isolation involves acid precipitation, extraction with the...

The problem of carbon dioxide emission from the soil is relevant, since it affects the reduction of the soil organic carbon pool, thereby reducing its fertility and productivity. In addition, carbon dioxide emissions from the soil are a significant contributor to the greenhouse effect. The aim of this work was to evaluate the mineralizing activity of the microbial community of the soil of a new point of observation of carbon dioxide emissions, located in the previously little-studied territory of Russia, using suc...
