摘要:
Provided herein are recombinant yeast cells comprising an engineered pyruvate utilizing biosynthetic pathway and further comprising a cell membrane with an altered lipid profile. In some embodiments the recombinant yeast cell has an increased tolerance to butanol as compared to a recombinant yeast cell that does not comprise an altered lipid profile. In some embodiments the altered lipid profile comprises an increase in the concentration of cyclopropane fatty acid as compared to a microorganism that lacks the cell membrane with an altered lipid profile. In some embodiments the altered lipid profile comprises an increase in the fatty acid concentration ratio.
摘要:
Synthetic, derivative promoters for expression of chimeric genes in Zymomonas , Zymobacter , and related bacteria were created. The promoters have a C to T change in the nucleotide at position 90 of the Z . mobilis glyceraldehyde-3-phosphate dehydrogenase gene promoter. Promoters with this change have higher expression as compared to the native promoter from which they are derived and are useful for genetic engineering for expressing coding regions or regulatory RNA to obtain high levels of expressed proteins or regulatory RNAs.
