Embodiment 3

[0055] The best combination of embodiment 3 carbon source and the screening of carbon-nitrogen ratio

[0056] 3.1 Orthogonal experiment

[0057] 3.1.1 Experimental scheme

[0058] According to the screening results of carbon and nitrogen sources, three carbon sources of corn flour, sucrose and glucose were selected as composite carbon sources in the experiment, and two nitrogen sources of soybean meal and yeast powder were selected as composite nitrogen sources. Orthogonal experiments were designed by using SPSS software. Orthogonal factors and The levels are shown in Table 3.1.1, 5 factors + 4 levels, to determine the best combination and ratio of carbon and nitrogen sources.

Abstract

The invention provides a carbon and nitrogen source for a Phellinus igniarius fermentation medium. The carbon source comprises corn flour, and the nitrogen source comprises soybean meal and yeast powder. The carbon source concretely comprises, by weight, 10-15 of glucose, 15-20 parts of sucrose and 15-25 parts of the corn flour; and the nitrogen source concretely comprises 10-20 parts of the soybean meal and 0-10 parts of the yeast powder. The carbon and nitrogen source provided by the invention can greatly improve the biomass and the bioactivity of Phellinus igniarius mycelia.

Description

technical field [0001] The invention belongs to the field of phellinus fermentation, in particular to a carbon and nitrogen source used for a phellinus fermentation medium. Background technique [0002] Phellinus is a class of very precious large fungi with important medicinal value, belonging to Basidiomyctina. It grows in a few places such as Japan, Philippines, Australia, China and North America. Phellinus often parasitizes on the dead wood of mulberry trees, and the fruiting bodies are perennial and woody. In China, Phellinus has been used for more than 2,000 years since the Han Dynasty. "Compendium of Materia Medica" records that Phellinus can "benefit the five internal organs, benefit the stomach, and expel toxins." It is regarded as a panacea for liver disease and cancer by the folks, and is known as "the best strain". [0003] Due to the particularity of the Phellinus growth, the number of natural Phellinus is very scarce, and the resources available for medicinal...
