[Submerged culture conditions for production of mycelial biomass and exopolysaccharides by Phellinus baumii].
OBJECTIVE
To investigate the submerged culture conditions and nutritional requirments for the production of mycelial biomass and exopolysaccharides (EPS) by medicinal mushroom Phellinus baumii.


METHODS
The carbon sources, nitrogen sources, inoculum volume, initial pH and temperature were investigated based on shake flask cultures, respectively.


RESULTS
The glucose was the most suitable carbon source for both mycelial biomass and EPS production, soy peptone was favorable nitrogen sources for both mycelial biomass and EPS production. The optimal inoculum volume, initial pH and temperature for both mycelial growth and EPS production were 6%, 6.0 and 28 degrees C, respectively.


CONCLUSIONS
The study obtained basic datas for large-scale submerged culture of P. baumii.
