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] This embodiment relates to a method for preparing a decolorizing agent, including the following steps:

[0038] 1) Mix the Pleurotus ostreatus residue with the citric acid buffer solution with a pH of 4.8 in a mass-volume ratio of 1:6, and then shake the Pleurotus citrinopileatus in a shaker at 190rpm for 4 hours at 28°C. Extraction, the supernatant obtained after centrifugation is the extract a, and the bottom sediment is the residue of bacteria residue;

[0039] The Pleurotus citrinopileus fungus residue is the culture medium remaining after cultivating the Pleurotus citrinopileus for 22-25 days and harvesting the mushrooms; the Pleurotus citrinopileus is cultured on the following medium, including 58 parts by weight of kenaf stem , 20 parts of sawdust, 20 parts of bran, 1 part of gypsum, 1 part of lime;

[0040] 2) After drying the residue of the bacteria residue, add distilled water to it until the water content is 50-65%, inoculate the oyster mushroom strain in it, and c...

Embodiment 2

[0043] Compared with Example 1, the difference is that in the step 1), the Pleurotus ostreatus residue 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 lies in that in the step 1), the Pleurotus ostreatus residue and citric acid with a pH of 4.8 are slowly mixed in 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 reuse of Pleurotus citrinopileatus fungus residue, in particular to a decolorizing agent containing Pleurotus citrinopileus fungus residue extract. Background technique [0002] In recent years, dyes have been widely used in textiles and colorant manufacturing industries due to their low prices, strong stability to light, temperature and detergents, and diverse colors (Asgher et al, 2008). With the rapid development of the textile industry, the variety and quantity of dyes continue to increase, and the printing and dyeing industry has become one of the largest water consumers and pollution sources in my country's natural water bodies. The decolorization of dyes is a key issue in the treatment of dye wastewater. There are mainly two types of methods to treat dye wastewater: physical and chemical methods and biological methods. Biological methods have the characteristics of strong continuous degradation ability, environ...
