Search for antagonists to protect plant raw materials from pathogens

Abstract

The paper presents the results of research on the selection of biological agents with antagonism to microorganisms affecting raw materials of plant origin. The antagonists selected at the first stage showed significant changes in the antagonistic activity of various isolates when the temperature of the medium increased to 450C. There was no decrease in activity in isolate 20, so it is resistant to high temperature. Isolate No.21 had a significant increase in antagonistic activity, it is likely to be more resistant to high temperatures and some biochemical enzymatic processes are stimulated, leading to increased antagonistic properties. And in isolates 9, 16 and 23, on the contrary, it was lowered, possibly due to the fact that the increased temperature causes structural and biochemical changes in the cell of the microorganism. Similarly, isolated isolates No.9, 16, 23, 21, and 15 had high antagonistic activity against micromycetes that contaminate plant-based feed.

Microorganism Isolates Stimulate Forest Crop Growth and Protection

“…A restoration of forest and agricultural lands ensures a sustainable development of the ecosystem. It is an important tool in a land management that increases biodiversity, CO2 sequestration, carbon content in the soil (as part of humus) and prevents an uncontrolled transport of pollutants within the ecosystem [4][5][6][7][8]. A forestry on unproductive lands unsuitable for agriculture, as well as the forest restoration and re-introduction of forest species, are of a paramount importance in the economic and recreational sphere of social development [9][10][11][12].…”

“…These reasons have a strong impact on public perception and market demand, creating a need to move towards the products free of synthetic pesticides in a healthier and more environmentally friendly manner. From this perspective, a promising alternative to pest management is the biological control approach, in which human intervention exploits the natural antagonistic effects of biological agents to mitigate the harmful effects of plant pathogens [4].…”
