Problems solved by technology

At present, it has been found that algae, white rot fungi, yeasts, actinomycetes, and various bacteria can degrade crystal violet dyes, but different strains have different decolorization rates to crystal violet, and different environmental conditions affect the decolorization efficiency of strains Larger, according to existing reports, the optimum pH value for most strains to decolorize dyes is in the neutral range, etc.

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, and the content of the present invention is not limited to the following embodiments.

[0019] The method for obtaining and identifying the Ochrobactrum sp.ZTS-1 bacterial strain of the present invention is as follows:

[0020] In this example, the bacteria isolated from the waste water of a tannery in Xiantao, Hubei Province were named ZTS-1. The morphological, physiological and biochemical characteristics of the strain are as follows: the colony was milky white with rounded edges when observed on the beef extract peptone medium , Slightly raised, the colonies are small and moist; the microscopic observation shows that the strain is a bacillus, Gram-negative, with a length of about 0.8-2.5 μm and a width of about 0.5 μm.

[0021] Inoculate ZTS-1 strain into 5mL beef extract peptone culture solution (3.0g beef extract, 10.0g peptone, 5.0gNaCl, distilled...

Abstract

The invention relates to the field of biology, in particular to a strain of Ochrobactrum sp. ZTS‑1 and its application. The strain is preserved in the China Center for Type Culture Collection, address: Wuhan University, Wuhan, China; zip code 430072, the preservation date is January 10, 2020, the preservation number is: CCTCC NO: M2020034, and the taxonomic name is Ochrobactrum sp.ZTS‑ 1. In decolorization of crystal violet dyes, the strain has the characteristics of rapid decolorization of crystal violet, wide range of temperature adaptation and wide range of pH value adaptation, and has broad application prospects.

Description

technical field [0001] The invention relates to the field of biology, in particular to a strain of Ochrobactrum sp. ZTS-1 and application thereof. Background technique [0002] Synthetic dyes are common pollutants in industrial wastewater. They have extremely bad impact on the environment. Because of their high chroma, they are more toxic to animals and aquatic organisms. Most of them contain benzene rings with strong stability in their molecular structures. It is difficult to degrade naturally in the environment, making the removal or decolorization of synthetic dyes from industrial wastewater one of the main problems faced in the current dye wastewater treatment process. [0003] Triphenylmethane dyes are the most widely used dyes in the printing and dyeing industry, accounting for about 30-40% of all synthetic dyes. Crystal violet is a typical triphenylmethane dye, which is widely used in various fields such as printing and dyeing, biology and medicine. The molecular st...
