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...
