This utility model discloses a spiral conveying device for seasoning sauce production based on temperature-controlled sterilization, comprising: a conveying cylinder, horizontally arranged with U-shaped heating elements embedded in the outer wall in sections, each U-shaped heating element being connected to a temperature control device; and a spiral conveying mechanism penetrating the conveying cylinder, including a main shaft and spiral blades for spirally conveying the seasoning sauce, with a gap between the outer edge of the blades and the inner wall of the cylinder. By dividing the U-shaped heating elements outside the conveying cylinder into heating and constant temperature zones along the conveying direction, a closed-loop temperature control system is formed in conjunction with an inner wall temperature sensor and a PLC controller. The heating power of each zone can be dynamically adjusted according to the conveying speed of the seasoning sauce, achieving gradient temperature control of the sauce according to a preset temperature rise curve during the conveying process, avoiding the problems of local overheating or insufficient sterilization temperature caused by traditional single heating elements. At the same time, the synergistic effect of ultraviolet light on the lifting cover plate destroying the DNA structure of microorganisms and thermal sterilization significantly improves sterilization efficiency and uniformity.

This invention provides an L-homoserine-producing strain, its construction method, and its applications. The strain does not contain plasmids. E.coli W3110, as a chassis strain, had the relA and thrB genes knocked out, and heterologously expressed genes derived from... Clostridium acetobutylicum The gapC gene and the aspB gene derived from Bacillus subtilis were overexpressed, along with ppc, asd, and thrA. fbr ,rhtA,pntAB,spoT fbr Genes; the strain described above can effectively improve the L-homoserine synthesis efficiency by knocking out genes of the L-homoserine degradation pathway, enhancing the expression of key enzymes in the pathway, optimizing the L-homoserine transport system, increasing the reducing power NADPH content, and enhancing the ability to withstand amino acid starvation. It is genetically stable, requires no addition of resistance substances, has high acid production efficiency, and has good L-homoserine synthesis capacity.

This invention relates to the field of molecular genetics, specifically to a ZmKS3 gene mutant, primer pair composition, kit, detection method, and application. The ZmKS3 gene mutant is obtained by a single-base mutation in the ZmKS3 gene, with the gene number Zm00001d002349. The ZmKS3 gene mutants are ks3-32, ks3-42, ks3-68, ks3-79, ks3-78, or ks3-80. This invention, through EMS mutagenesis technology, creates and screens a series of different amino acid mutation sites distributed within the coding region of the ZmKS3 gene, significantly enriching the germplasm resource bank for maize dwarfing breeding, effectively compensating for the lack of allelic variation in this gene, and providing a foundation for the discovery of new high-quality dwarf materials.
