The metabolism of levoglucosan (1,6-anhydro-β-d-glucopyranose) in several microorganisms was studied. Although levoglucosan could be easily hydrolyzed to glucose with acid, all of the tested yeasts and fungi strains had no activity hydrolyzing it. O

Rice-straw treated with 5% ammonia water was hydrolyzed with the beta-xylanase of Streptomyces sp. E-86, and four kinds of hetero-oligosaccharides, two arabinoxylo- and two glucuronoxylo-oligosaccharides, were isolated from the hydrolysate by charcoa
