Sorroche, Fernando G.; Giordano, Walter – Biochemistry and Molecular Biology Education, 2012
Exopolysaccharide (EPS) production by the rhizobacterium "Sinorhizobium meliloti" is essential for root nodule formation on its legume host (alfalfa), and for establishment of a nitrogen-fixing symbiosis between the two partners. Production of EPS II (galactoglucan) by certain "S. meliloti" strains results in a mucoid colony…
