Abstract: The disclosure relates to a tyrosol-producing recombinant Escherichia coli and a construction method and application thereof and belongs to the technical field of bioengineering. The Escherichia coli undergoes heterologous expression of a codon-optimized Saccharomyces cerevisiae pyruvate decarboxylase gene ARO10*. According to the recombinant Escherichia coli, five sites of a lacI site, a trpE site, a pabB site, a pabA site and a pykF site of an Escherichia coli genome are deleted, and at the same time, the ARO10* gene is integrated at each site of the five sites to obtain a strain containing multiple copies of the ARO10* gene. On the basis of the above recombinant strain, the ARO10* gene is randomly integrated at multiple sites, and it is found that a strain with high-yield production of tyrosol can be obtained by inserting the ARO10* gene at a yccX site. Fermentation using this strain does not require inducers or antibiotics. After fermentation is carried out for 48 hours, the yield of tyrosol can reach 32.

Abstract: An electroluminescent phosphor powder includes copper-activated zinc sulfide particles that have a size distribution with a D50 value of no more than 10 ?m, where no more than 25% of the particles have a size greater than about 15 ?m and/or a 24-hr brightness of at least 15 footlamberts. These particles are made by a method that includes first firing copper-doped zinc sulfide mixed with zinc oxide, sulfur and a chloride-containing flux, rapidly cooling the mixture to below 100° C., and then mulling and second firing the mixture to provide a powder. The powder can then be elutriated to provide the electroluminescent powder with a narrow particle size distribution (more than 90% between about 5 and 15 ?m). The elutriating step can be avoided (albeit with a slightly wider size distribution) by more tightly controlling the first firing temperature.

The phosphor produces a yellow emission having an x color coordinate from 0.420 to 0.500 and y color coordinate from 0.420 to 0.460 when stimulated by an electric field.
