DRIED BIOLOGICAL COMPOSITIONS AND METHODS OF THEIR OBTAINING Russian patent published in 2023 - IPC C12N1/20 C12N11/14 A01N63/20 A01N63/27 

FIELD: biotechnology.

SUBSTANCE: dried biological composition for the delivery of microorganisms that can be used in agriculture (variants) is proposed; a method of production of a dried composition; and a method of controlling insects, fungi or nematodes on a treated surface, comprising applying an effective amount of an optionally diluted composition to the treated area are proposed. The composition includes a silica substrate and Clonostachys rosea or Pseudomonas fluorescens microorganisms applied to the surface of the substrate, with a total moisture content of about 0.01 wt.% to about 15 wt.%; the pore volume of the substrate is approximately 0.01–1.20 cm³/g based on the Barrett-Joyner-Halenda model, or the surface area of the BET substrate is approximately 400–600 m²/g and the pore volume is greater than 1 cm³/g per based on the Barrett-Joyner-Halenda model, or more than 2 cm³/g according to mercury porosimetry.

EFFECT: inventions provide obtaining microorganisms in a dried, stable form with a high content of colony-forming units.
