Beneficial effects of intracellular trehalose on red blood cells by freeze drying;

This study was aimed to further optimize trehalose loading technique including loading temperature, loading time, loading solution and loading concentration of trehalose, based on the established parameters.

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.
