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 chryseobacterium and application thereof. The strain is the chryseobacterium; the strain is named as Chryseobacterium sp GZU-Ch01, and is preserved in typical culture Storage Center in China on December 19, 2017, and the deposit number is CCTCCNO: M2017810. The Chryseobacterium sp. GZU-Ch01 can effectively decompose insoluble potassium, phosphorus, silicon, calcium, sulfur and other components in coal gangue into quick-acting potassium, effective phosphorus, effective silicon, exchangeable calcium, effective sulfur and the like absorbed by plants as nutrients. In particular, the GZU-Ch01 can effectively dissociate the insoluble potassium from the coal gangue into the quick-acting potassium, provide a valuable source of potassium resources, has a good dissociation effect on other potassium-containing minerals, add other potassium-containing minerals such as potassium feldspar to the coal gangue, and can further enhance the potassium content of a mineral microbial compound fertilizer using the coal gangue as a base material.

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...
