Embodiment

[0032] A strain of Bacillus pumilus provided by the present invention, which is called Bacillus pumilus CFC-5 (Bacillus pumilus CFC-5), is preserved in the Guangdong Microbial Culture Collection Center (abbreviated as GDMCC), and it is stored in the Guangdong Provincial Microbial Culture Collection Center. The preservation number is GDMCC No: 60397, and the preservation time is June 25, 2018. The address of the preservation unit is located at Guangdong Institute of Microbiology, 5th Floor, Building 59, Compound, No. 100 Xianlie Middle Road, Guangzhou City.

[0033] 1. Screening of bacterial strains

[0034] 1) Source of tung oil cake: sampling from oil tung processing enterprises.

[0035] 2) Tung cake extract juice medium: tung cake cake 200g, soaked at 60-90°C for 3-4 hours, filtered through 8 layers of gauze to remove the residue to obtain tung meal juice, set the volume to 1000mL, and packed in 250mL triangular flasks. The bottled volume is 50mL, and the pH is natural.

Abstract

The invention discloses a bacillus pumilus strain. The bacillus pumilus strain is preserved in the Guangdong culture collection center on June 5, 2018, is named as bacillus pumilus CFC-5, and has a preservation number of GDMCC NO:60397. The bacillus pumilus CFC-5 strain is able to degrade protein in tung cake, has a broad spectrum inhibition effect for soil-borne diseases of crops, has a growth promoting effect and provides a strain source to tung cake degrading. The invention further discloses application of the strain in degrading protein in tung cake and inhibiting crop diseases.

Description

technical field [0001] The invention belongs to the technical field of microbial engineering, and in particular relates to a strain of Bacillus pumilus and its application. Background technique [0002] Tung tung is a native woody oil tree species in my country, which has the advantages of fast growth, high yield, wide adaptability, high seed oil content and rich nutrition. The tung cake after tung seed oil extraction contains 4% to 6% nitrogen, P 2 o 5 1.8%~2.7%, K 2 O 1.2% ~ 1.3%, and a large number of other trace elements, is an excellent protein resource. However, because tung tree cake contains toxins such as saponin, phorbol and related chemical substances, tung tree cake has been used as cake fertilizer for a long time and cannot be used as a source of animal food. [0003] In agricultural production, the excessive use of high-nutrient and convenient chemical fertilizers has brought about various agricultural and environmental problems: soil nutrient loss, environ...
