Embodiment 1

[0021] Example 1: Screening of Cladosporium like Cladosporium

[0022] Soil samples were collected from various places, and different culture media were used for screening, and multiple strains were screened out, and the dye degradation experiments were carried out one by one, and the strains for degrading dye were obtained, and the strains were identified.

Embodiment 2

[0023] Embodiment 2: the preservation of Cladosporium like Cladosporium

[0024] It was deposited in the General Microorganism Center of China Committee for the Collection of Microorganisms, with the preservation date being March 2007 and the preservation number being CGMCC No.1987.

Embodiment 3

[0025] Embodiment 3: the condition optimization of the cultivation of Cladosporium-like Cladosporium and degradation dye

[0026] Strain cultivation: Prepare liquid potato culture medium at the ratio of 200g / L potato extract and 20g / L glucose, and sterilize at 121°C and 0.1MPa for 25min. Take sterilized Petri dishes, and add 10 mL of liquid potato culture medium to each Petri dish aseptically. After the culture medium was cooled to room temperature, the isolated strain of Cladosporium cladosporioides TXJ13021 was inoculated into a petri dish and cultured for 6-7 days to form a bacterial film for subsequent experiments.

[0027] Dyes used for degradation: commonly used dyes such as methyl orange (characteristic wavelength 476nm), methyl red (characteristic wavelength 430nm), malachite green (characteristic wavelength 617nm), crystal violet (characteristic wavelength 583nm), aniline blue (characteristic wavelength wavelength 585nm), alizarin red (characteristic wavelength 420nm...

Abstract

The invention provides a whole set of engineering technology for preventing dyes from polluting the environment by a microbiological method for aiming at the deficiencies of a traditional related dye pollution and poisoning control technology, thereby effectively reducing the environmental pollution of the dyes such as anthraquinone dyes, azo dyes, triarylmethane dyes, phthalocyanine and the like and effectively protecting the environment. The invention is a cleaning engineering technology.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and pollution prevention and control, and specifically relates to a method for efficiently reducing and synthesizing dyes by using a microbial method and an application thereof. Background technique [0002] 1. Characteristics of dye pollution [0003] Synthetic dyes are common water pollutants in printing and dyeing industrial wastewater, with complex components, high concentration (1000-100,000 mg / L of COD), and deep chroma (500-500,000 times). Most of the organic components in wastewater are based on aromatic hydrocarbons and heterocyclic compounds, and have chromogenic groups (such as -N=N-, -N=O) and polar groups (such as -SO 3 Na, -OH, -NH 2 ). Wastewater also contains more raw materials and by-products, such as halides, nitros, anilines, phenols, etc., as well as inorganic salts such as NaCl, Na 2 SO4, Na 2 S, there are also anthraquinone dyes, azo dyes, triarylmethane...
