Welan gum produced by Sphingomonas spp ATCC 31555 (formerly known as Alcaligenes sp. ATCC 31555). Welan gum is also an anionic HePS, which is composed of l‐mannose, l‐rhamnose, d‐glucose, and d‐glucuronic acid in the molar ratios 1.0:4.5:3.1:2.3. The side chain present could be either l‐rhamnose or l‐mannose [3]. Welan gum was previously known as EPS S‐130 and commercially produced by CP Kelco, division of J.M. Huber Corporation. The molecular weight of welan gum is about 1000 kDa, and it is non‐gelling polysaccharide, unlike gellan explained above [32]. Even so, welan possesses high viscosifying properties due to which it has wide‐spread applications in cement technology and oil drilling industries. It has the potential to be used for food application as it can act as a thickening, suspending, binding, and emulsifying agent [3].
