Currently, the description of <i>Sinorhyzobium meliloti</i> M5N1CS mutant bacterial strain as the sole source of glucuronan makes it relevant to the exploration of new microorganisms producing glucuronan. In this study, the <i>Peteryoungia rosettifformans</i> strain (Rhizobia), was identified as a wild producer of an exopolysaccharide (RhrBR46) related to glucuronan.
