Biomics

For many bacteria, biofilms serve as a physical barrier against toxic compounds and protection against adverse environmental conditions. In addition, for nodule bacteria (rhizobia), biofilm formation is a factor determining the competitiveness of rhizobia strains in soil conditions. In this process, an important role is played by exopolysaccharides (EPS), the biosynthesis and functions of which for Rhizobium leguminosarum are currently insufficiently studied, unlike, for example, Sinorhizobium meliloti. This article discusses basic information about the structure and biosynthesis of EPS in R. leguminosarum, describes the main functions of EPS, as well as experiments with genes associated with the synthesis of EPS, with the aim of modifying biofilm formation, including for biotechnology.
