Genetically modified microorganisms that have the ability to convert carbon substrates into chemical products such as 2,3-BDO; 1,4-BDO; isobutyraldehyde; isobutanol; 1-butanol; n-butanol; ethanol; fatty alcohols; and fatty acid methyl ester are disclosed. For example, genetically modified methanotrophs that are capable of generating 2,3-BDO; 1,4-BDO; isobutyraldehyde; isobutanol; 1-butanol; n-butanol; ethanol; fatty alcohols; and fatty acid methyl ester at high titers from a methane source are disclosed. Methods of making these genetically modified microorganisms and methods of using them are also disclosed. These microorganisms and methods make use of molecular switches to regulate gene expression.
已公开的转基因微生物具有将碳底物转化为化学产品的能力,如 2,3-BDO;1,4-BDO;异丁醛;异丁醇;1-丁醇;正丁醇;乙醇;脂肪醇和脂肪酸甲酯。例如,公开了能够从甲烷源产生高滴度的 2,3-BDO;1,4-BDO;异丁醛;异丁醇;1-丁醇;正丁醇;乙醇;脂肪醇和脂肪酸甲酯的转基因甲烷营养体。还公开了制造这些转基因微生物的方法和使用它们的方法。这些微生物和方法利用分子开关来调节基因表达。
