METHOD FOR PRODUCTION OF LICHEN THALLUS Russian patent published in 2025 - IPC A01H15/00 

FIELD: biotechnology.

SUBSTANCE: invention is a method of recovering arctic wastelands, involving mixing lichens with carrier material, which is a mixture of fragments of bark and/or branches, stones with size of 3–5 cm and peat, preliminarily treated by wetting with a nutrient solution of the biopreparation "Biolipostim", mixed with water in ratio of 1:20, and carrier material with lichens fixed on it is placed in container, which is then placed for growing during storage in a growth chamber with a controlled light mode at a design light intensity of 10 to 90 mcmol m²*s with controlled temperature mode, which is from 10–15° at night, and from 15–20° during the day, and with alternation of dry and wet phases for a time providing for germination of lichen spores, obtaining planting material, lichen used is at least one of lichen symbiotic fungi and algae, and/or cyanobacteria, and/or lichen bodies, method includes introducing and fixing the obtained planting material into an object for ecological restoration, lichens and carrier material are mixed at the following ratio, wt.%: carrier material—from 1.0 to 3.5, lichen—the rest.

EFFECT: invention makes it possible to ensure mass production of lichen thallus for recovery of arctic wastelands, allowing use of lichen symbiotic algae, lichen bodies participating in formation of lichen thallus for recovery of arctic barrens.
