Abstract

The minimum medium without carbon source was used to investigate the effects of five kinds of hexoses, four kinds of pentose, four kinds of bi-saccharide and three kinds of polysaccharides on Tremella aurantialba growth. The result demonstrated that (1) The fittest carbon source of T. aurantialba was the five-carbon aldose in all the tested monosaccharides; (2) Polysaccharides linked with β-1,4-glycosyl bond is fitter for the growth of T. aurantialba than that linked with α-1,4-glycosyl bond  (3) Corncob, which contained abundant poly-xyloses linked with β-1,4-glycosyl bond, is the fittest for growth of T. aurantialba. The reaction system of α-1,4-glycosidase was employed to study the  reason that the polysaccharides linked in β-1,4-glycosyl bond is fitter for growth of T. aurantialba. The result showed that T. aurantialba broth can inhibit the activity of α-1,4-glycosidase produced by T. aurantialba.

Key words: Tremella aurantialba, glycosyl bond, carbon source, aldose, ketose.
