The invention discloses an enrichment culture method and application of a lignin degrading bacterial system. The enrichment culture method comprises the following steps: inoculating an inoculum into an enrichment culture medium for culture; the enrichment culture medium comprises sodium salt, ammonium salt, potassium salt, magnesium salt, 3, 4-dimethyl pyrazole phosphate and lignin; the inoculum is derived from an organic material containing lignin degrading microorganisms. Through the enrichment culture, the efficient lignin degrading bacterial system can be obtained; the lignin degrading bacterial system can degrade lignin at the temperature of 15 DEG C and has the characteristic of low temperature resistance; the lignin degrading bacterial system is subjected to passage for many times, and the degradation rate is stable; the bacterial system is mainly prepared from the following components: pseudomonas (Pseudomonas), Achromobacter (Achromobacter) and sphingobium (Sphingobium).

The present application relates to the technical field of biotechnology, and particularly relates to a bacterium YKS2 and application thereof, the bacterium YKS2 is preserved in the China General Microbiological Culture Collection Center on April 14, 2022, and the preservation number is CGMCC No. 24678, has good acid resistance, bile salt resistance, artificial gastric juice resistance and artificial intestinal juice resistance, can improve immunity, and has wide application prospect.

This invention provides *Achromobacterium* and its inoculum, and their application in constructed wetland treatment of thallium-containing wastewater. The *Achromobacterium* strain is *Achromobacterium* QBM-4, deposited at the China Center for Type Culture Collection (CCTCC), accession number: CCTCC NO: M20211051, deposit date: August 18, 2021. The inoculum is obtained by fermentation of *Achromobacterium*. This invention utilizes this strain to catalyze the in-situ generation of "bio-derived manganese oxide (Bio-MnOx)" within a wetland system, achieving selective fixation of thallium. This results in a removal rate of >99% for low-concentration thallium-containing wastewater with extremely low operating costs, while simultaneously meeting the requirements of economy, high efficiency, and stability. It can be applied to the treatment of thallium-containing wastewater in constructed wetlands.

The present invention relates to a microorganism belonging to the genus Rhodococcus, the genus Xanthobacter, the genus Ancylobacter, the genus Shewanella, or the genus Aeromonas, and a method for producing the same, and more specifically, to a microorganism belonging to the genus Rhodococcus, the genus Xanthobacter, the genus Ancylobacter, the genus Shewanella, or the genus Aeromonas. The microorganism can be Rhodococcus hedyotidis (Rhodococcus cerevisiae) of the genus Rhodococcus, Xanthobacter flavus (Xanthobacter flavus) of the genus Xanthobacter, or Ancylobacter rudongensis of the genus Ancylobacter, and the microorganism can be a microorganism of the genus Ancylobacter, or a microorganism of the genus Ancylobacter, or a microorganism of the genus Ancylobacter, or a microorganism of the genus Ancylobacter and a microorganism of the genus Ancylobacter. The microorganism can be used for promoting the growth of blue algae, green algae, grey algae or euglena. The microorganism can be used to promote the growth of an organism belonging to the phylum cyanobacteria, unequal flagellum, euglenophyta, cryptophyta, rhodophyta, chlorophyta or chalaphyta.

The application provides a method for rapidly degrading petroleum hydrocarbon in high-salt oil-containing wastewater, adopts Pseudomonas Z1 and denitrifying achromobacter M1 for compounding, adds auxiliary liquid to obtain a bacterial agent, the degradation speed of the bacterial agent on petroleum hydrocarbon and the load tolerance of the bacterial agent on COD in wastewater are obviously higher than those of single bacterial species, and the bacterial agent has good salinity adaptability. In actual wastewater biochemical treatment, the bacterial agent can rapidly establish the bacterial community advantage in a small amount and a short time, effectively improves the microbial abundance and diversity in the system, and can achieve a better petroleum hydrocarbon degradation effect in a limited hydraulic retention time in continuous operation.

The application discloses a microbial agent for promoting growth of cucumbers, a preparation method and application thereof, and belongs to the technical field of agricultural microorganisms. The microbial agent comprises the following components: denitrifying achromobacter, Bradyrhizobium elkanii and Azotobacter vinelandii, and the volume ratio of the three is 2:1:1. The bacteria with growth promotion are reasonably combined and used, so that the mixed bacterial flora of the application is superior to a single strain in terms of growth promotion effect on cucumbers, and the synergistic effect among the bacterial strains is more adaptable in the actual soil rhizosphere complex environment. Through determination of the number of bacterial strains and mixing of specific proportions, the growth of cucumber seeds is stably and effectively promoted, the root elongation is promoted, the flowering and fruit setting rate is improved, and the plant height, plant biomass and chlorophyll content of cucumber seedlings are improved. In addition, the microbial agent can help improve the growth quality and yield of plants, reduce environmental pollution, has wide application potential in the fields of agriculture and ecology, and is worth promoting.
