Diutan gum produced by Sphingomonas sp. ATCC 53159 under aerobic conditions. Diutan differs from other sphingans by possessing a disaccharide of l‐rhamnosyl units as a side chain. Diutan gum can act as thickening, binding, suspending, stabilizing, and emulsifying agent. Diutan gum is used in concrete and cement due to its ability to improve the viscosity of cement paste [22].
