Abstract
A process at various pH values ranging from 4.5 to 7.5 for production of mycelia and extracellular polysaccharide (EPS) by P. linteus fermentation in pH-controlled shaken bioreactor was investigated. A two-stage pH control strategy in which pH value was kept at 6.5 for the first 24 h, and then switched to 4.5 was developed successfully to enhance simultaneously the cell growth and EPS production. The maximum cell density and EPS production reached 15.13 +/- 0.1 g/l on day 6 and 6.74 +/- 0.1 g/l on day 4, respectively. The anti- hyperlipemia effect of EPS and intracellular polysaccharide (IPS) extracted from mycelia were observed that both EPS and IPS can obviously reduce the serum triglyceride (TG), the blood cholesterol (TC) and serum low density lipoprotein (LDL) level, and increase the high density lipoprotein (HDL) level of the hyperlipemia mice. Polysaccharides from submerged cultivation of medicinal fungus P. linteus have favorable potency to develop anti-hyperlipermia drugs.
