発明の名称 (英語) TRANSGENIC MICROORGANISM CAPABLE OF PRODUCING MUCONIC ACID, AND USE THEREOF 新技術説明会
発明の概要(英語) The purpose of the present invention is to provide: a microorganism which enables the production of muconic acid with good economic efficiency and high yield; and a method for producing muconic acid utilizing the microorganism. The purpose can be achieved by: a transgenic microorganism of which a host microorganism is a microorganism belonging to the genus Pseudomonas and has pcaH gene, pcaG gene, catA gene and catB gene on the chromosome thereof and in which the pcaH gene, the pcaG gene and the catB gene on the chromosome are deleted, and inserted pcaH gene and inserted pcaG gene can be expressed and inserted aroY gene is also expressed; a method for producing muconic acid using the transgenic microorganism; and others.
従来技術、競合技術の概要(英語) BACKGROUND ART
Vascular plant cell wall components of lignin as the amorphous polymer substance is present, the complexity of the configuration of the fuzed unit-phenylpropane and, on the chemical structure containing a methoxy group are the features.Wood lignins are stuck to each other and to a plant cell, and serves to enhance the tissue, wood in an 18-36%, about 15-25% in the presence of the herbaceous.Therefore, to effectively utilize wood, and decomposition of lignin, an attempt to obtain useful compounds have been made various.
On the other hand, cis, cis - muconic acid (hereinafter, simply sometimes referred to as muconic acid.) Is, the carboxyl group and double bond in the molecule by 2 pieces, is a compound having high reactivity.Muconic acid as a starting material of the various known and muconic acid derivatives, for example, lactone, sulfone, polyamide, polyester, a thioester, additional polymers and the like.Such as muconic acid derivatives, various applications are known as having, for example, surfactants, flame retardants, UV light stabilizers, thermosetting plastics, may be used as coating agents.
In this way, muconic acid are, muconic acid derivatives are subjected to a variety of applications in the form of a result, lignin muconic acid can be produced, the reproduction of the resources is achieved, very useful.Therefore, a material derived from lignin or a lignin, muconic acid has been attempted a method of manufacturing.Particularly as such a method, the microorganisms of the bioconversion is used has been studied.
For example, the following Non-Patent Document 1 (described in the literature as disclosed herein all of which are hereby incorporated.) Is, Pseudomonas, putida ( Pseudomonas putida) as a host microorganism, a gene on a chromosome and gene pcaH pcaG (hereinafter, sometimes referred to as gene pcaHG with.) As well as gene catR, catB gene, the gene and catC catA gene disruption, and, inserted into the gene aroY catA gene, a gene or gene ecdB catA aroY gene expression to produce a transformed microorganisms, the microorganisms grown transformed glucose, caffeic acid then was muconic acid p- is described.
