Abstract: Containing rich polysaccharides ,amino acids and mineral elements,Grifola frondosa which may be produced by submerged fermentati on in larger scale was edible -medicinal fungi.By analyzing effects on submerged fermentation of nutrit ion factors ,factors and levels were obtained.When the weight of dry fungi was used as the target,by orthogonal test which contained 4factors and 4levels,the optimum component of medium of Grifola frondosa was as follows:potato 250g,glucose30g ,yeast cream 1.0~2.5g,KH 2 PO 4 2~5g,MgSO 4 0.5~2g,water 1L.The optimum weight of dry fungi was 19.7g /L.The effect on target of the mass concentration r atio of carbon source was prominent.The test results were different when compared with those results in o ther articles.

Key words: Grifola frondosa, fermentation, medium, optimization
