Abstract
Deserts represent one of the most inhospitable environments on Earth characterized by extreme daily variations in temperature, limited availability of nitrogen and water, high salinity levels, and other challenging conditions. Within these arid zones, cyanobacteria emerge as a crucial group of organisms capable of actively thriving. They form complex communities known as biocrusts, which not only ensure their own survival, but also significantly contribute to the persistence of other organisms within these ecosystems. Cyanobacteria, through their metabolic activities, play a significant role in the establishment and functioning of soil ecosystems. They are capable of generating primary organic matter, fixing molecular nitrogen, and synthesizing metabolites with potent biological activities. To endure the relentless pressures of their environment, desert cyanobacteria have evolved intricate adaptive strategies to enhance their resilience against multiple concurrent stresses. One such mechanism involves the production of secondary metabolites, enabling them to cope with the extreme conditions of drought and salinity. This comprehensive review delves into the ecological significance of desert cyanobacteria in the context of soil improvement. Additionally, the latest advancements in utilizing cyanobacteria to combat desertification and prevent soil degradation are elucidated.
期刊介绍：
Eurasian Soil Science publishes original research papers on global and regional studies discussing both theoretical and experimental problems of genesis, geography, physics, chemistry, biology, fertility, management, conservation, and remediation of soils. Special sections are devoted to current news in the life of the International and Russian soil science societies and to the history of soil sciences.
Since 2000, the journal Agricultural Chemistry, the English version of the journal of the Russian Academy of Sciences Agrokhimiya, has been merged into the journal Eurasian Soil Science and is no longer published as a separate title.
