Using gel overlay techniques,we detected extracellular calmodulin-binding proteins (CaMBPs)with biotinylated calmodulin in body fluid of animal.

Studies on separation of extracellular polysaccharide from Porphyridium cruentum and its anti-HBV activity in vitro;

Determination of Extracellular Polysaccharide from Submerged Fermentation Broth of Clitocybe Gigantean;

Study on submerged fermentation and extraction conditions of AT01,a strain of Acremonium terricola extracellular polysaccharide;

Optimization of culture medium composition for exopolysaccharides production by Lactobacillus casei LC2W;

Optimization of exopolysaccharide production conditions fermented by Streptococcus thermophilus from Tibetan kefir;

Review on the characteristics and compositive influence factors of exopolysaccharides produced by lactic acid bacteria;

The results showed that,two reaction mechanisms of enzyme-catalyzed reaction and thermal-hydrolyzed reaction were involved in the S-TE process,which began with depolymerization of sludge flocs by exoenzymes including proteases and amylases,followed by cell-walls and organic matters disintegration and hydrolyz.

The decomposition of exoenzyme controls the material circulation of wetland ecosystem, which is the restricted step of the decomposition process of organic matters in wetland ecosystem.
