Abstract
Sinorhizobium meliloti (Rhizobium meliloti) 2011 has the ability to produce the two acidic exopolysaccharides succinoglycan (EPS I) and galactoglucan (EPS II). EPS I is a branched heteropolysaccharide composed of octasaccharide repeating units, whereas EPS II is a linear heteropolysaccharide consisting of disaccharide subunits. The exo-exs and exp gene clusters are involved in the biosynthesis of EPSI and EPSII, respectively. EPSI and EPSII biosynthesis genes are differentially expressed resulting in a complex regulation of EPS production in S. meliloti. The phosphate concentration was identified as an important factor affecting the expression of exp genes.Entities:
