The strain and the preparation thereof are mainly used for preparing microbial products with the functions of fixing nitrogen, dissolving phosphorus, producing iron carriers and promoting the growth of the curcuma kwangxi.

The invention provides a straw degrading bacterium and application of the straw degrading bacterium. The straw degrading bacterium is prepared from microbacterium sp. SDM28 (Microbacterium sp. SDM28) and bacillus (Bacillus sp. SDM29). Through mutual cooperation of microbacilli and bacillus, during straw degradation treatment, compound bacteria can synergistically generate high-activity cellulose degradation related enzymes, lignocellulose structures in straw can be efficiently decomposed, and especially the content of hemicellulose components can be remarkably reduced; the problems that existing straw degrading microorganisms are low in degrading efficiency and difficult to decompose complex lignocellulose structures are solved; meanwhile, the compound bacteria have mild requirements on environmental conditions, the application range focuses on the high-yield straw type of rice straw, large-scale application can be realized without complex regulation and control, resource waste and environmental pollution caused by slow natural decomposition after straw returning to the field are reduced, the resource utilization process of the straw can be promoted, and the economic benefit is increased. The requirements of large-scale and efficient straw treatment can be met.

This invention belongs to the field of agricultural microbiology technology, specifically relating to a microbacterium strain and its application in plant disease control.

The application discloses a high-enzyme-activity xanthan backbone cleavage enzyme mutant and a preparation method thereof. Microbacterium sp. ​ The application discloses a high-enzyme-activity xanthan backbone cleavage enzyme mutant and a preparation method thereof, wherein the wild-type xanthan backbone cleavage enzyme of XT11 is subjected to site-directed mutation, and the mutation point of the site-directed mutation comprises at least one of W753V, H755G and L810S. The xanthan backbone cleavage enzyme mutant of the application can directly degrade the xanthan backbone without side chain pretreatment, thereby simplifying an enzymolysis system, and the enzyme activity of the mutant after being treated by using an alkaline buffer system at 55 DEG C is obviously improved compared with the original enzyme, wherein the three-mutant W753V / H755G / L810S has the largest improvement range, and the three-mutant W753V / H755G / L810S overcomes the limitation that a traditional xanthan cleavage system depends on side chain pre-deconstruction.

The invention provides a new strain of Microbacterium for promoting growth of larvae of hermetia illucens and application of the new strain. The strain comprises a 16S rDNA sequence shown in SEQ ID NO: 1 or a complementary sequence of the 16S rDNA sequence or a sequence with at least 85% of nucleic acid identity compared with the sequence shown in SEQ ID NO: 1.
