The invention discloses a strain of the genus Chryseobacterium and an application thereof. The strain is Chryseobacterium sp; National Object Collection Center, the collection number is CCTCCNO: M2017810. Chryseobacterium sp GZU-Ch01 of the present invention can effectively decompose insoluble potassium, phosphorus, silicon, calcium, sulfur and other components in coal gangue to become available potassium, available phosphorus, available silicon, exchangeable calcium, effective Sulfur, etc. are used as nutrients absorbed by plants. In particular, GZU‑Ch01 can effectively dissociate insoluble potassium in coal gangue, making it into available potassium, which provides a valuable source of potassium resources. The gangue is mixed with other potassium-containing minerals such as potassium feldspar, which can further increase the potassium content in the mineral and microbial compound fertilizer based on coal gangue.

The invention discloses Chryseobacterium sp. for removing phosphorus in sewage at low temperature and a separation culture method. The Chryseobacterium sp. deep yellow polyphosphorus CGMCC No.5282 for removing the phosphorus in the sewage at low temperature has the ability of removing the phosphorus in the sewage at low temperature under aerobic conditions. The experimental result shows that: in spite of obvious inhibition of a low-temperature environment, the Chryseobacterium sp. deep yellow polyphosphorus CGMCC No.5282 for removing the phosphorus in the sewage at low temperature has a remarkable effect of strengthening the removal of the phosphorus at low temperature, especially at the temperature of between 8 and 12 DEG C, and the removal rate of the phosphorus is improved by 10 percent; and the effluent standard is superior to the first-grade A effluent standard (water temperature is less than or equal to 12 DEG C, and the control index of the first-grade A standard is 0.5mg / L).

The invention provides a biological iron-removing manganese-removing functional bacterium, which relates to a microorganism. The invention solves the problems that the present biological oxidation manganese removing engineering flora is established by natural selection, the biochemical capability is weak, the manganese removing effect is poor; the establishment of the water treatment removing manganese biologic filter pond needs a long time for cultivation, domestication and startup, and the restoring period after the engineering flora is damaged is long. The biological iron-removing manganese-removing functional bacterium MSB-4(Chryseobacterium sp.) belongs to flavobacterium, is preserved in the General Microorganism Center of China Commission of Culture Collection Management, the storagedate is 30 Octomber 2007, the storage number is CGMCC No.2239; strain MSB-4 is aerobic strain, the length is 1.5-2 micrometers, the width is 0.8-1.1 micrometers, the strain is short rod-shaped cell with two blunt ends; brown yellow colony is formed on the substrate, the colony is non-transparent and round; the strain MSB-4 has metachromatic granules and lipoid granules, has no brood cell; N, N, N<1>, N<1>-tetramethyl-para-phenylene diamine stain is positive. The biological iron-removing manganese-removing functional bacterium MSB-4 of the invention has the capability for removing the Mn<2+>,<Fe2+> in the water, Mn<2+> removing rate can reach up to 94.44 percent, and the Fe<2+> removing rate can reach up to 90.13 percent.

The invention provides a strain of Chryseobacterium that efficiently degrades picolinic acid and its application, belonging to the technical field of bioengineering. The present invention isolates and screens a picolinic acid-degrading bacterium, Chryseobacterium sp., which is classified as Chryseobacterium sp. and is preserved in the General Microorganism Center of China Committee for the Collection of Microorganisms, with the preservation number CGMCC NO.10699. The advantage of the present invention is that this Chryseobacterium can effectively degrade picolinic acid under the condition that the pH value range is wider or the temperature range is wider, and the pH value range is wider and the temperature range is wider; The aerobic biological treatment of picolinic acid wastewater in a wide temperature range from weak base to weak acid has broad application prospects.

The invention provides a microorganism for promoting black nightshade to remove trace cadmium pollution in water and a method for removing cadmium pollution, aiming to purify drinking water subjected to cadmium pollution by virtue of the high-efficiency absorption characteristic of super-accumulated plants, namely black nightshade, to cadmium. In the method, the black nightshade is cultured in anaquaculture manner, and Chryseobacterium sp. LKS03 is inoculated to the black nightshade to promote the roots of the black nightshade to grow; and during purification of drinking water, the roots of black nightshade plants are immersed into the drinking water subjected to cadmium pollution, and each black nightshade plant correspondingly purifies about 1-1.2L of the drinking water in a purification cycle, wherein the purification time is for 2-12h according to the cadmium ion concentration (not higher than 200mug / L) in a water sample, and the capability of the black nightshade plants for purifying the water sample is optimum in the 45th-80th day in the culture cycle of the black nightshade. The method is specific to the cadmium pollution in the drinking water and has the advantages of good removal effect, simplicity and convenience for operation, wide applicable range, and great application potential in the aspect of drinking water purification.
