摘要:
A microbial cell is used for producing at least one fatty acid ester, wherein the cell is genetically modified to contain (i) at least one first genetic mutation that enables the cell to produce at least one fatty acid and/or acyl coenzyme A (CoA) thereof by increased enzymatic activity in the cell relative to the wild type cell of malonyl-CoA dependent and malonyl-ACP independent fatty acyl-CoA metabolic pathway, wherein the fatty acid contains at least 5 carbon atoms; and (ii) a second genetic mutation that increases the activity of at least one wax ester synthase in the cell relative to the wild type cell and the wax ester synthase has sequence identity of at least 50% to a polypeptide of SEQ ID NO: 1-8 and combinations thereof or to a functional fragment of any of the polypeptides for catalyzing the conversion of fatty acid and/or acyl coenzyme A thereof to the fatty acid ester.

摘要:
Embodiments of the present invention provide methods and compositions for microorganisms having increased alcohol tolerance. In certain embodiments, methods for using such microorganisms, and methods for identifying gene or genetic regions responsible for increased alcohol tolerance are contemplated.
摘要:
The present disclosure concerns methods and compositions relating to mixed-library parallel gene trait mapping. In particular embodiments, the methods concern quantitative microarray hybridization techniques for genome-wide identification of trait conferring genes. In other embodiments, the compositions concern genetic elements that confer or are associated with a trait. In an exemplary embodiment, the trait is enhanced growth rate. In another exemplary embodiment, genetic elements that confer enhanced bacterial growth rate comprise part or all of the sequences of SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, SEQ ID NO:4 or SEQ ID NO:5. In other embodiments, the genetic elements that confer enhanced bacterial growth rate correspond to the YliF, adrA, yeaP, yddV or ydeH genes of E. coli.
摘要翻译:本公开涉及与混合型库并行基因性状图谱相关的方法和组合物。 在具体实施方案中,该方法涉及定性微阵列杂交技术,用于全基因组鉴定赋予特性的基因。 在其它实施方案中,组合物涉及赋予或与性状相关的遗传元件。 在一个示例性实施例中,性状是增强的增长率。 在另一个示例性实施方案中,赋予增强的细菌生长速率的遗传元件包含SEQ ID NO:1,SEQ ID NO:2,SEQ ID NO:3,SEQ ID NO:4或SEQ ID NO:5的部分或全部序列 。 在其他实施方案中,赋予增强的细菌生长速率的遗传元件对应于大肠杆菌的YliF,adrA,yeaP,yddV或ydeH基因。
