Optimization of fermentation condition about extropolysaccharide by Bacillus sp
Polysaccharide is a biological polymer which exists widely in animals, plants, microorganisms. It has a wide variety of biological activity and function. It is security harmless. In recent years, it become the hot spot of the research and development. In this paper, the optimum of fermentation condition for extracellular polysaccharide by Bacillus subtilis were primarily studied and applicated in the Single factor and Orthogonal test. The results indicated that the optimum of fermentation condition was as follows: the optimum of fermentation temperature 37t, wave bed speed 160rpm, inoculum rate 3% , Fermentation time 36h. After the optimum condition, the extracellular polysaccharide output 4. 135g/L.
