A method for producing a target substance is provided. A target substance is produced by culturing a coryneform bacterium, which is able to produce a target substance, and which also has an improved ability to assimilate xylose as a result of the introduction of a mutation into a coding region and/or an expression control region of the NCgl2954 gene on the chromosome of the bacterium. The culture is conducted in a medium containing xylose, and the target substance can be collected from the medium.
本发明提供了一种生产目标物质的方法。目标物质的生产是通过培养一种能够生产目标物质的棒状杆菌来实现的,由于在该细菌染色体上的 NCgl2954
基因的编码区和/或表达控制区引入了突变,该细菌同化
木糖的能力也得到了提高。在含有
木糖的
培养基中进行培养,可从
培养基中收集目标物质。
