Submerged culture Grifola frondosa produce trehalose;

Biosynthesis of trehalose and its relative enzymes;

Using chemical mutagenesis to selective breeding of the trehalose producing strain;

Recent advances in seaweeds polysaccharide-survey on structure,extraction and biological activity;

At present, the research of seaweeds polysaccharide causes more and more peoples’ interests.

New progress in the research on bioactivities and applications of alginate, a kind of marine algal polysaccharide;

To study the toxicity and lightening effect of several natural active products on cultured B16 melanocytes cells of mouse,arbutin and two kinds of algal polysaccharide were added into B16 melanocytes cells and the cell viability,tyrosinase activity and melanin content were measured respectively.

The activity and medical Application of seaweed polysaccharides;

In this paper, a review and prospect to the progress in the study on anti-tumor effect and its related mechanism of seaweed polysaccharides were reported according to recent literatures at home and abroad.
