| Abstract: | The Edible Tremalla fuciformis was the experimental strain in this paper.Through the slope agar and the shaking flask culture and cross test of submerged fermentation,we search for the medium component druing different culture stage. The result was considered that seed culture medium was : potato 20%, glucose 2%, peptone 0. 2%, KH_2PO_4 0. 15%, MnSO_4 0. 01, CMC-Na 1%. Submerged fermentation culture medium was : potato 1. 5%, corn flour 2. 0%, (wheat) bran 3%,KH_2PO_4 0. 2%, Tween-800. 10% . Polysaccharide of mycelium of fermentation product was 13. 23%, protein 32. 83%, amino acid 19. 75%/100g dry mycelium, essential amino acid 7. 69mg/100g dry mycelium. |
