Abstract

The invention provides a synthetic medium for culturing a phellinus igniarius liquid. The synthetic medium takes glucose as a carbon source and 20 kinds of amino acid as a nitrogen source, and consists of inorganic salt and vitamin. The ratio of carbon to nitrogen is designed as 50 to 1; and the specific concentration g/l is as follows: the glucose: 30 to 80 grams; glutamic acid: 0.1 to 1.5 grams; glutamine: 0.1 to 1.5 grams; aspartic acid: 0.1 to 1.5 grams; asparagines: 0.1 to 1.5 grams; glutamic acid: 0.01 to 0.1 gram; tryptophan: 0.01 to 0.1 gram; valine: 0.01 to 0.1 gram; alanine: 0.01 to 0.1 gram; etc. During the whole culture process of the synthetic medium, phellinus igniarius mycelium is quick in growth; the yield of the phellinus igniarius mycelium can reach 20 grams per liter to the highest degree; simultaneously no agricultural and sideline product is introduced as the carbon source and the nitrogen source; substances such as proteins in the medium, medium compositions and so on are not carried; phellinus igniarius exopolysaccharide produced through fermentation has high purity and stable quality; and the yield of phellinus igniarius polysaccharide can reach 0.198 gram per liter to the highest degree. The synthetic medium has the advantages of clear compositions, stable quality and so on, and can be used for mass culture of the phellinus igniarius liquid and research of the regulation and control rule of polysaccharide anabolism.

Description

technical field [0001] The invention belongs to the field of biological technology, and in particular relates to a fully synthetic medium used for the liquid cultivation of the medicinal fungus Phellinus phellidis and a method for producing Phellinus polysaccharide by fermenting the Phellinus phellidis using the medium. Background technique [0002] Phellinus igniarius, also known as Phellinus igniarius, belongs to Basidiomycetes, Phellinus igniarius, parasitic on mulberry trees, is a rare edible and medicinal fungus, the main active ingredient of Phellinus igniarius is Phellinus polysaccharide , can improve the body's immunity, has significant anti-tumor activity, and is of great development value. [0003] Due to the complexity and particularity of the physiological ecology of Phellinus fungus, the number of Phellinus fruiting bodies is scarce. Large-scale production of Phellinus mycelium and its active polysaccharides by liquid submerged culture technology is an effectiv...
