Abstract: Provided are a recombinant gene associated with increased galactose catabolism, and a recombinant vector and microorganism including the gene. Also disclosed are a method of producing ethanol from a galactose-containing carbon source by culturing the microorganism including the gene in a galactose-containing carbon source such that ethanol is produced, and a method of screening a gene in yeast resulting in increased galactose catabolism when overexpressed.

Abstract: Provided herein are a recombinant vector and microorganism including the isolated SNR84 gene, and a method of increasing volumetric productivity of biofuel from a galactose-containing carbon source using the isolated SNR84 gene, the recombinant vector or the recombinant microorganism. Also disclosed herein is a method of screening yeast for genes associated with increased galactose catabolism when the genes are overexpressed.

Abstract: The present invention provides genetically manipulated cells and methods for utilizing same. Methods of enhanced carotenoid synthesis utilizing cells genetically disrupted for a yjiD, hnr or yjfP gene, or further disrupted for a gdhA, gpmB aceE, ppc, talB or fdhF gene, or any combination thereof, or cells inhibited for their expression, activity or function are disclosed. Methods of enhanced carotenoid synthesis utilizing cells genetically engineered to overexpress dxs, idi, yjiD, rpoS, torC, appY, ydgK, yeiA, yedR, tort, arcB, yggT, purDH, yfjN or a combination thereof, or further disrupted for the above-referenced genes are disclosed. Methods for identifying genes involved in optimized production of a carotenoid, and cells disrupted for, or inhibited for the expression, activity or function of genes thus identified are described.

Abstract: Disclosed are xylose-fermenting recombinant yeast strains comprising heterologous PsXYL1, Ps XYL2, and PsXYL3, as well as methods of fermenting xylose to obtain ethanol using the recombinant yeast strain.
