摘　　要：威伦胶(welan Gum,又名威兰胶或韦兰胶),是由产碱杆菌Alcaligenes Sp.(ATCC31555)以碳水化合物为主要原料,经发酵产生的高分子可溶性胞外杂多糖,过去的名称为S-130,是美国的Kelco公司上世纪80年代继黄原胶和结冷胶之后开发的最具市场前景的微生物代谢多糖之一。因其出色的流变学特性和独特的分子结构而在石油开采、建筑、食品等领域有广泛的应用开发价值。目前只有美国的Cp.kelco公司拥有韦兰胶产业化技术,国内还未见韦兰胶产业化报道。本文简要介绍了韦兰胶的结构及其性能;综述了它在食品工业、石油工业、医药工业以及水泥工业中的应用;介绍了国内外对韦兰胶的研究生产现状、存在的问题以及目前的市场前景。Welan gum is a kind of high molecular soluble extracellular polysaccharide produced by Alcaligenes Sp.（ATCC31555）（previously named S-1 30）in an aerobic submerged fermentation.Welan gum is one of the most prospective microbial polysaccharides in the market and was developed by CpKelco,an American company in 80＇.Welan gum in aqueous media has an excellent rheological properties,and its special molecular structure made it possible to be used from oil drilling industry to construction industry and food industry.Till now CpKelco is the only company who has industrial production of welan.Large scale production of this polysaccharide has not been reported in China.In this paper,the molecular structure and physical-chemical properties of Welan gum are introduced.Its applications in the food industries,petroleum industries,medicine industries and cement industries are described.The current research and production status,the problems and development situation are also introduced.
