Abstract: A method for preparing a xylose-utilizing strain of Saccharomyces cerevisiae and the Saccharomyces cerevisiae are introduced. The preferred recombinant strain contains multiple copies of integrated xylose metabolic genes, and can rapidly ferment xylose to produce ethanol from synthetic medium and lignocellulosic raw materials. The xylose-utilizing strain is applicable for the cellulosic ethanol production industry and brewing industry.

Abstract: An oil body carrier, its uses in target therapy and/or detection, and a fusion protein comprised therein are provided. The oil body carrier comprises: a) the fusion protein, comprising an oil body protein and a ligand peptide, an antibody peptide, a cell penetrating peptide, or combinations thereof, and b) a lipid, wherein the weight/volume (?g/?l) ratio of the fusion protein and the lipid is at least about 1/25, and the average particle size of the oil body carrier is about 10 nm to about 2,000 nm.

Abstract: The present invention is related to a method to promote cell growth, comprising: (a) cloning one or more aspartase coding sequence into a vector to become a recombinant vector, wherein the recombinant vector including a promoter and one or more aspartase coding sequences manipulated to link and insert into the downstream of said promoter; (b) transforming the recombinant vector into host cells and producing recombinant host cells; and (c) culturing the host cells in culture medium and making the cells to express aspartase, then promoting said recombinant host cells growth. The aspartase can not only promote cell growth but also increase the amount of the target gene expression.

Abstract: Disclosed herein are nucleic acid constructs and expression vectors for enhancing the production of recombinant polypeptides/proteins, and methods for the massive production of recombinant polypeptides/proteins, in which a first nucleic acid sequence encoding thioredoxin and a second nucleic acid sequence encoding hemoglobin are cloned into a host cell, thereby enhancing the capability of the thus formed recombinant host cell in producing a selected gene product, and thereby assisting said recombinant host cell in relieving intracellular stress due to the overproduction of said gene product.
