This invention relates to a method for efficiently spraying soil conditioner to treat saline-alkali land using composite microorganisms, belonging to the field of soil improvement technology. The method involves screening salt-tolerant functional microbial strains to prepare a composite microbial agent, which is then mixed with carrier materials such as diatomaceous earth, soybean meal, yeast metabolites, and well-rotted farmyard manure in a specific ratio to form a conditioner for application. The conditioner is applied using a two-stage spraying method, combined with deep tillage pretreatment and controlled temperature and humidity conditions, significantly improving microbial activity and soil condition uniformity. Experimental data show that after applying this method, the soil pH value decreased to 7.3-7.5, the salt content decreased to 0.1%-0.2%, and the organic matter content increased to 18-22 g / kg, achieving efficient ecological restoration and sustainable utilization of saline-alkali land.

This application relates to the field of microbial strain technology, specifically disclosing a Bacillus thuringiensis HP-SYJ2 strain and its applications. The Bacillus thuringiensis HP-SYJ2 strain is deposited at the China Center for Type Culture Collection (CCTCC), accession number: CCTCC NO: M2025343, deposit date: March 3, 2025, address: Wuhan University, Wuhan, China.

The application relates to the technical field of microbial strain preservation, in particular to a microbial strain preservation device which comprises a freezer, a moving assembly and a rotating assembly, the freezer is provided with a box door, a fixing seat is arranged in the freezer, the end of the fixing seat is provided with a supporting disc, a plurality of groups of test tube racks are fixedly connected to the supporting disc, and the bottom end of the supporting plate is fixedly connected with a connecting shaft; the moving assembly is arranged in the freezer and is used for driving the supporting disc to displace; and the rotating assembly is used for driving the connecting shaft to rotate, so that the supporting disc rotates. The moving assembly and the rotating assembly are arranged, the connecting shaft drives the supporting plate to move a small distance through the action of the moving assembly, part of the position of the supporting disc is moved to the outside of the freezer, then the connecting shaft drives the supporting disc to rotate through the cooperation of the rotating assembly, and then the strain at any position on the supporting plate can be taken and placed, so that the operation is more convenient.

The invention relates to a recombinant microbial strain for de novo synthesis of gardenin B and application of the recombinant microbial strain in production of polymethoxylated flavone compounds, and belongs to a cross technology of synthetic biology and organic synthetic chemistry. The invention designs and constructs a heterozygous gardenin B biosynthesis pathway, and obtains a microbial strain for synthesizing gardenin B from the beginning. By screening F8H and redox partner types and regulating and controlling subcellular localization, an F8H-redox partner combination with optimal space and type is determined, and an engineering strain of which the gardenin B yield is greatly improved is obtained. The efficient synthesis method of the polymethoxylated flavonoids is established by selecting recombinant microorganisms for synthesizing gardenin B from de novo to perform co-culture fermentation or chemical conversion of fermentation products.

Microbial starter cultures. More specifically, a method for preparing a microbial culture such as a lactic acid bacteria (LAB) starter culture wherein at least one microbial strain such as a lactic acid bacteria and at least one inactivated yeast strain is inoculated in a culture medium.

This invention belongs to the field of microbial fermentation technology, specifically relating to a new strain of Pichia pastoris (Kudelazwiel). Pichia Kudryavzevii ) and its applications. To stabilize and target the production of ethyl acetate in baijiu (Chinese liquor), this invention screens, isolates, and identifies a strain of *Pichia pastoris* capable of high ethyl acetate production from soy sauce-flavored baijiu mash. Pichia kudriavzevii LJ-5, with accession number CCTCC NO:M20252599, is a strain that enhances the fermentation of lees. In baijiu brewing, it can be used to produce ethyl acetate, ethyl lactate, and other flavor compounds, especially significantly increasing the content of ethyl acetate produced during fermentation. Therefore, this strain can be applied to baijiu production as a functional microbial strain to improve baijiu quality.
