ABSTRACT
Phosphate is an effective factor in the regulation of cell growth and accumulation of polysaccharides. The method for higher polysaccharide production has been obtained through feeding cultivation. The two-stage cultivation was proposed according to the characteristic of cell growth and the accumulation of polysaccharides in the suspension cultures of protocorm-like bodies from Dendrobium huoshanense. A kinetic model was developed to describe the cultivation process. The results indicate that the production of biomass and polysaccharides increases from 28.7g DW/L and 1.86g/L to 44.2g DW/L and 5.22g/L, respectively, and the content of polysaccharides increases from 6.4% to 11.9% . With the evaluated model parameters, the model appears to provide a description for the cultivation process.
