For example, a selective advantage results from transformation of a cell with a nucleic acid that allows a transformed cell to metabolize one or more nitrogen-, phosphorous-, and/or sulfur-containing compounds that a native cell of the same species as the transformed cell cannot metabolize, and from fermentation of the transformed cell using one or more feedstocks, such as fractioned grain, which are depleted in or free of conventional nitrogen-, phosphorous-, and/or sulfur-containing compounds that a native cell of the same species as the transformed cell can metabolize. Also disclosed are methods for improved oxygen transfer in an aerobic or microaerobic fermentation.

Abstract: The invention relates to the ADH3 promoter; polynucleotide sequences, vectors and expression cassettes including DNA regions responsible for the regulation of the ADH3 promoter; the host cells, including these vectors and expression cassettes, and, the recombinant proteins performed with the developed cells. In the scope of the invention, deletion analyzes in the ADH3 promoter were performed to identify regions that affect promoter strength and significant data was obtained in the formation of mutant ADH3 promoters. Deletion of the nucleotides between 539 and 638 (?361 to ?262) in SEQ ID NO: 1 resulted in a 63% increase in ADH3 promoter activity. Five different synthetic promoters were created using positive regulatory regions identified and approximately 165% to 200% promoter activities were achieved with these promoters.
