Problems solved by technology

[0003] With the rapid development of my country's edible fungus industry, a large number of edible fungus residues are continuously produced, but the comprehensive utilization rate of the mushroom residues is low, and most of the residues are discarded. On the one hand, it causes environmental pollution, and on the other hand, it breeds miscellaneous bacteria and pathogenic bacteria , bringing safety hazards to large-scale production areas of edible fungi

Embodiment 1

[0037] The present embodiment relates to a kind of preparation method of decolorizing agent, comprises the steps:

[0038] 1) Mix the fungus residue of the yellow fungus and the citric acid buffer solution with a pH of 4.8 at a mass volume ratio of 1:6, then shake it in a shaker at 190 rpm for 4 hours at 28°C, and carry out the Extraction, the supernatant obtained after centrifugation is the extract a, and the lower part of the precipitate is the residue of bacteria residue;

[0039] The dregs of the yellow elm mushrooms are cultured for 22 to 25 days after the mushrooms are harvested; the yellow mushrooms are cultured on the following medium, including 58 parts of kenaf stalks in parts by weight , 20 parts of sawdust, 20 parts of bran, 1 part of gypsum, 1 part of lime;

[0040] 2) add distilled water to it after drying the residue of the bacteria residue until its water content is 50-65%, inoculate Pleurotus ostreatus strains in it, and cultivate it statically for 21 days un...

Embodiment 2

[0043] Compared with Example 1, the difference is that in the step 1), the residue of Pleurotus chrysanthemum and citric acid with a pH of 4.8 are slowly mixed at a mass volume ratio of 1:5 and then extracted.

Embodiment 3

[0045] Compared with Example 1, the difference is that in the step 1), the residue of Pleurotus chrysanthemum and citric acid with a pH of 4.8 are slowly mixed at a mass volume ratio of 1:4 and then extracted.

Abstract

The invention relates to a decolorizing agent with pleurotus citrinopileatus dregs extract. A method for preparing the decolorizing agent includes 1), extracting pleurotus citrinopileatus dregs by theaid of citric acid buffer solution to obtain extract liquid a and dregs residues; 2), inoculating pleurotus ostreatus strains on the dregs residues, carrying out fermentation culture and then extracting mixed products of culture media and mycelia by the aid of citric acid buffer solution to obtain extract liquid b; 3), mixing the extract liquid a and the extract liquid b with each other to obtainthe decolorizing agent. The decolorizing agent has the advantages that the decolorizing agent is mixed liquid of the extract liquid of the pleurotus citrinopileatus dregs and the extract liquid obtained after dregs solid portions are used for culturing pleurotus ostreatus, synergistic effects can be realized after the two types of extract liquid are mixed with each other, and decolorizing effectsof the decolorizing agent are superior to decolorizing effects individually realized by optional one of the two types of extract liquid.

Description

technical field [0001] The invention relates to the field of reutilization of fungus slag of ulmus chrysanthemum, in particular to a decolorizing agent containing an extract of fungus slag of ulmus chrysanthemum. Background technique [0002] In recent years, dyes have been widely used in textile and colorant manufacturing industries due to their low price, strong stability to light, temperature and detergent, and various colors (Asgher et al, 2008). With the rapid development of the textile industry, the variety and quantity of dyes are constantly increasing, and the printing and dyeing industry has become one of the largest water resource consumers and pollution sources of natural water bodies in my country. The decolorization of dyestuff is the key problem of dyestuff wastewater treatment. There are two main methods for treating dye wastewater: physical chemical method and biological method. Biological methods have the characteristics of strong sustainable degradation a...
