Corncob is the optimum carbon resource for the growth of Tremella aurantialba

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.
