摘　　要：细菌胞外多糖是当今进入工业化发酵生产的一类重要的多糖。由于多糖种类的不同,其分离纯化工艺不尽相同。本文综述细菌胞外多糖发酵生产中提取分离技术的研究进展,并比较了各种分离技术,介绍了针对极具商业价值的微生物多糖的几种新型提取分离技术,展望了微生物多糖研究的发展趋势。Bacterial exocellular polysaccharides are important in industrial fermentation now. Because of different species, the technologies of extraction and isolation are different for each polysaccharide. All the technologies applied usually at home and abroad in fermentation industry are reviewed in this paper and compared with each other. The paper also introduces some new technologies and methods for the extraction and isolation of certain valuable polysaccharides, and gives an outlook about the progress on bacterial exocellular polysaccharides.
