Stability of terrestrial ecosystems under the influence of steroid glycoalkaloids

Abstract

Abstract Soil-transmitted helminths are one of the most pressing problems of the urban area. Worm infestations are diseases with a high (more than 50%) mortality rate among both children and adults. Therefore, one of the most pressing safety problems of not only the technosphere, but also the homosphere, is the search for methods of disinfestation of the soil cover of urban areas with a minimum load on the biota and ecological risk tending to zero. As a solution to this problem, it is proposed to use secondary plant metabolites (steroid glycoalkaloids) as a means for disinfecting various environmental objects: wastewater and their sediments, soil, sand of playgrounds, etc. The effect of various concentrations of potato juice (Solanum tuberosum) on the components of terrestrial ecosystems on the shores of water bodies: higher plants (oats (Avenum sativa)) and soil microflora (soil micromycetes Aspergillus niger, Aspergillus terrius, Alternaria alternaria, Fusarium moniliforme) was studied. Revealed moderate phytotoxicity for Avenum sativa, as well as a strong stimulatory effect for Fusarium moniliforme and Alternaria alternaria.
