Embodiment

[0026] The isolation of Chryseobacterium genus GZU-Ch01 comprises the following steps:

[0027] 1. Isolation and screening of functional strain GZU-Ch01

[0028] 1) Collection of samples

[0029] (1) The sample is collected from a coal gangue hill in a coal production area, and the completely weathered gangue is selected, and the collected sample is put into a collection bag;

[0030] (2) crush and sieve the sample collected, and collect a 100-mesh sample;

[0031] (3) Store the samples in a 4°C refrigerator for later use;

[0032] (4) The composition of the gangue sample is: C 8.24%, SiO 2 40.56%, Al 2 o 3 19.46%, Fe 2 o 3 15.12%,TiO 2 4.61%, CaO 3.32%, MgO 2.5%, K 2 O 1.66%, Na 2 O 0.6%, P 2 o 5 1.42%, S1.07%, H 0.88%, N 0.54%, ash 82.81%.

[0033] 2) Screening of functional strains

[0034] (1) Accurately weigh 1g of sample into a sterilized 250mL Erlenmeyer flask, and add 99mL of sterile water;

[0035] (2) Then shake for 30 minutes in a constant tempera...

Abstract

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.

Description

technical field [0001] The invention relates to a strain of the genus Chryseobacterium and application thereof, in particular to a strain of the genus Chryseobacterium for dissociating coal gangue to release potassium, phosphorus, silicon, calcium and / or sulfur. Background technique [0002] my country is a country where coal is the main energy source. Coal resources are abundant, widely distributed, and complete in variety. Coal plays a pivotal role in my country's economic development. Coal gangue is a kind of solid waste with low carbon content and harder than coal produced in the process of coal mining and washing, accounting for about 15%-20% of the original coal output. Over the years, it is estimated that billions of tons of coal gangue have been discarded in various coal-producing areas in China, and most of them are piled up in the open air, forming countless coal gangue hills, which have not been effectively utilized so far. [0003] The coal gangue stacked in the...
