摘要：

A levan-producing bacterium was isolated from soil. Cultural and physiological characteristics of the isolate identified the organism as a strain of Bacillus polymyxa. The organism's characteristics for polysaccharide synthesis were studied. The bacterium produced polysaccharide in high yield when grown on sucrose solution. Hydrolysis and subsequent analysis showed the product to consist entirely of D-fructose.13C NMR and methylation analyses indicated the product to be a β(2→6)-linked polymer of fructose, with 12% branching. The polysaccharide has a molecular weight of about 2 million and is readily soluble in water. © 1990, American Chemical Society. All rights reserved.
