Abstract: |
In the natural environment, exopolysaccharides are a common feature of microbial biofilms and play a key protective and structural role, being among the first participants in the synthesis of exopolysaccharides that form the extracellular polymeric matrix and cause the formation of microbial aggregations with varying levels of complexity called biofilms. Cyanobacteria are among the first organisms to establish themselves in environments with less favorable conditions, such as desert soils and rocky and uncovered substrates, and by synthesizing exopolysaccharides, they create a hydrated microenvironment with structural strength as well as chemical/physical protection against living and non-living stressors, leading to the formation of biofilms. However, despite the important role of cyanobacterial exopolysaccharides, many aspects of their role and their relationship with biotic and abiotic factors are still unclear. Therefore, this review article examines their role in protecting the microbial community by searching for the latest articles.
