Abstract: Provided is a non-coding small RNA (sRNA) from Corynebacterium glutamicum and use thereof. An RNA sequence of the non-coding sRNA has at least 90% or more sequence identity to a transcription product of a DNA sequence shown in SEQ ID NO. 1. Experimental results demonstrate that overexpression of the non-coding sRNA in the recombinant bacterium can significantly increase yields of the branched-chain amino acids such as L-leucine, L-isoleucine, and L-valine and the sugar-to-acid conversion rate, while reducing generation of the byproduct acids. Regarding raw materials, relatively low-cost molasses is selected as a carbon and nitrogen source, corn steep liquor with a high impurity content is discarded, and molasses is converted via enzymatic hydrolysis into a nutrient containing more carbon and nitrogen sources utilizable by strains.

Abstract: An engineered strain for improving tryptophan production and a construction method and use thereof are provided. By screening out a strain capable of tolerating high-concentration tryptophan and performing genomic sequencing and protein sequence analysis on the strain, it is found that certain proteins in the strain undergo point mutations and these mutations are capable of enhancing tryptophan production. To increase tryptophan production, protein sequences encoded by fadR or pepD genes in a parent strain are modified. These modifications result in an engineered strain with significantly higher tryptophan production compared to the parent strain. Under scaled-up production conditions, the tryptophan production reaches 62.38±5.80 g/L in a 5 L fermenter, with a glucose-to-tryptophan yield of 24.1%. Compared to an original strain, tryptophan production increases by 1.48-fold, and the glucose-to-tryptophan yield improves by 1.26-fold.

The epitaxial structure is formed with first holes and second holes respectively at a first region and a second region that are independent from each other. Each of the first and second holes extends through the second semiconductor layer and the active layer, and partially exposes the first semiconductor layer. A surface of the first semiconductor layer exposed by the first holes has a total area greater than a total area of a surface of the first semiconductor layer exposed by the second holes.

Abstract: Microencapsulation of ?-alanine uses ?-alanine as a core material and a mixture of a wall material and an additive as a release material. The additive comprises: a fatty acid-based saturated or unsaturated fatty acid glyceride containing 12-22 carbon atoms and a phospholipid. The fatty acid glyceride is a mono-fatty acid glyceride or a di-fatty acid glyceride, or a mixture formed by mixing the mono-fatty acid glyceride and the di-fatty acid glyceride at arbitrary proportions. The microencapsulation technique solves problems occurring with the use of ?-alanine as a raw material, such as high moisture absorption tendency thereof, unpleasant smell and stinging accompanying administration of the same.

Abstract: The invention relates to a microencapsulated amino acid composition and methods of manufacturing this composition. Amino acids, such as branched-chain amino acids, have low water solubility, poor hydrophilicity, and poor stability. Amino acids are thus difficult to be digested and absorbed. Consequently amino acids can hardly meet human needs of consuming. This microencapsulated amino acid composition that can quickly disperse and dissolve in cold water, resulting clear solution. The method includes (1) adding coating agents, wetting agents, or other excipients to the amino acid mixture, (2) modifying the surface of microencapsulated particles to considerably accelerate the wetting speed. In this composition, the weight ratio of amino acids and excipients is from 100/0.1 to 100/10.0.
