Embodiment 1

[0033] A method for producing L-tryptophan by fermenting chaff. The raw material components for L-tryptophan produced by chaff fermentation include: 40 parts of chaff, 15 parts of millet, 9 parts of pinto beans, 12 parts of fermented yeast, phosphate buffer 13 parts of solution, 25 parts of 0.05-0.2% sodium chloride solution, 14 parts of soybean cake, 13 parts of yeast extract, 13 parts of peptone and 35 parts of water.

[0034] The method for producing L-tryptophan by fermentation of chaff comprises the steps:

[0035] (1) select high-quality chaff, remove chaff such as rotten chaff, put chaff into pulverizer and be pulverized into powder for later use;

[0036] (2) Add water to the chaff powder afterward, the chaff powder is dissolved into a thick liquid, and in the thick liquid, add 50% yeast extract to become a thick liquid solution;

[0037] (3) Finally, place the thick liquid solution in a shaker at 350rpm / min, and expose it to strong sunlight for 4 days to ferment natu...

Abstract

The invention discloses a method for producing L-tryptophan by husk fermentation and a use thereof and relates to the technical field of biological products. Raw materials for fermentation productionof L-tryptophan from husk comprise husk, millet, pinto beans, a yeast, a phosphate buffer solution, a sodium chloride solution with a concentration of 0.05-0.2%, soy bean cake, yeast extract, peptoneand water. The method increases L-tryptophan preparation raw material sources. The husk has a wide source and is natural and easily available so that the husk value is increased. The centrifugal precipitation paste after the fermentation is used as poultry feed, agricultural fertilizer, additive perfume in cigarettes and coatings in the chemical industry. The method can produce glutamic acid and increase the uses of the fermented spina date seeds.

Description

Technical field: [0001] The invention relates to the related technical field of biological products, in particular to a method and application for producing L-tryptophan by fermenting rice husks. Background technique: [0002] Rice husk, also known as rice husk, is the outer layer of rice husk. It is a significant task before us to study and solve the rational utilization of rice husk and turn waste into treasure. Rice husk is rich in cellulose, lignin, silica; very low in fat and protein. The most notable features of rice husk are high ash and high silica content, good toughness, porosity, low density and rough texture. [0003] In real life rice husks are often thrown away or buried and collected as farm manure for the growth of crops, but in real life rice husks have not been well used. [0004] L-tryptophan, also known as α-aminoindole propionic acid, molecular formula: C11H12N2O2, structural formula White to yellow-white crystal or crystalline powder. Odorless or ...
