Abstract
The present invention is aimed to provide a method for industrially producing a useful substance (protein etc.) utilizing a bacterium such as Escherichia coli in the presence of a surfactant and a surfactant to be used in this method for producing a useful substance. The present invention is a method for producing a useful substance into a culture solution by secretion by a bacterium in the culture solution, wherein the culture solution contains a surfactant (A), and a dried cell density based on the volume of the culture solution is 1.5 to 500 g/L. More preferably, the present invention is a method for producing a useful substance wherein the surfactant (A) is at least one agent selected from the group consisting of an amphoteric surfactant, an anionic surfactant, and a nonionic surfactant having an HLB value of 0 to 13.
