Technical field
[0001] The present invention relates to a polysaccharide extracted from algae extracellular fermentation broth, preparation and use thereof. Background technique
[0002] (Schizochytrium limacinum) Schizochytrium sp is a class of marine fungi belonging to Oomycetes fungi gate network sticky Thraustochytrium Division, it is a globular unicellular fungi. Thraustochytrium spoilage microorganisms belonging addicted, widely present in the organic-rich and high-salinity environments, such fungal growth speed fast, strong resistance, easy to mass culture, because such cells can be contained in the proportion of DHA dry cell weight reached about 20%, and therefore is ideal for industrial culture as a source of DHA species. While such microalgae fermentation of DHA, secrete large amounts of polysaccharides, polysaccharide or polysaccharide complexes such present outside the cell wall, the cells easily separated, it is called exopolysaccharide (EPS). These extracellular pol...
