摘　　要：使用Na2CO3将好氧颗粒污泥由凝胶颗粒转化为溶胶,并从中提取出占颗粒污泥干质量约(35.1±1.9)%的细菌藻酸盐,确定了好氧颗粒污泥中单一细菌胞外多糖组分——细菌藻酸盐的提取方法,使好氧颗粒污泥细菌胞外多糖的研究深入到单一多糖组分的层次。好氧颗粒污泥中细菌藻酸盐的发现,不仅证明了贫营养条件是好氧颗粒污泥形成的必要条件,为好氧颗粒污泥中细菌胞外多糖的深入研究奠定了基础,而且也表明了好氧颗粒污泥在农业、化学和医药等领域中潜在的应用前景。After transforming aerobic granulated sludge Irom gel to sol Na2CO3, nates were extracted successfully from the granules. The extraction rate amounted to （35.1±1.9）%.The extraction method of single extracellular polysaccharides, that is, bacterial alginates from aerobicgranulated sludge was determined to make the research on extracellular polysaccharides in aerobic granu-lated sludge thorough in single polysaccharides. The observation of bacterial alginates in aerobic granula-ted sludge proves that the poor nutritional condition is necessary for formation of aerobic granulatedsludge, which lays a foundation for further investigation on extracellular polysaccharides in aerobic granu-lated sludge. The observation indicates the potential application prospect of aerobic granulated sludge inagriculture, chemistry, medicine and other domains.
