Abstract:
The effects of four kinds of carbon sources and nine kinds of nitrogen sources on the fungus Phellinus nigricans mycelia were studied.The four kinds of carbon source are sucrose,lactose,glucose,soluble starch.The nine kinds of nitrogen source are corn meal,wheat bran,potato,soybean meal,yeast extract powder,peptone,potassium nitrate,ammonium nitrate,and urea.Polysaccharides were extracted from different generations of mycelia and the contents,monosaccharide components and molecular weight were analyzed.The results were that the optical carbon source and nitrogen source were starch and corn meal.The optical combination was sucrose and corn meal.The properties of polysaccharides from different generations of mycelia were stable.
