摘要:
Soil isolates, identified as strains of Bacillus polymyxa, NRRL B-18475 and NRRL B-18476, produce large quantities of a pure and uniform extracellular polysaccharide fructan (levan), in a sucrose medium. The levan consists entirely of fructose and the residues linked by .beta., 2-6 fructofuranoside linkage.
