Abstract
An object of the present invention is to provide a method that has less number of steps, improves the yield of terephthalic acid, and can inexpensively produce terephthalic acid from a biomass resource, while reducing the amount of energy consumption, and a method for producing polyester. The method for producing terephthalic acid comprises a step of converting a biomass resource or a compound derived from the biomass resource to p-tolualdehyde with a microbe. The method for producing polyester comprises a step of reacting terephthalic acid produced from a biomass resource with a diol compound to produce polyester.
Claims20
A method for producing terephthalic acid, comprising a step of converting a biomass resource or a compound derived from the biomass resource to p-tolualdehyde with a microbe.
A microbe transfected with a gene group encoding four types of enzymes, benzaldehyde dehydrogenase, toluate methylmonooxygenase, 4-carboxybenzyl alcohol dehydrogenase, and 4-carboxybenzaldehyde dehydrogenase, the microbe being capable of producing p-tolualdehyde from a biomass resource or a compound derived from the biomass resource.
A method for preparing a microbe transfected with a gene group encoding four types of enzymes, benzaldehyde dehydrogenase, toluate methylmonooxygenase, 4-carboxybenzyl alcohol dehydrogenase, and 4-carboxybenzaldehyde dehydrogenase, comprising a step of transfecting a microbe with the gene group, wherein the microbe is a microbe capable of producing p-tolualdehyde from a biomass resource or a compound derived from the biomass resource.
