Abstract
A method for producing a fibroin-like protein is provided. A fibroin-like protein is produced by a method of culturing Escherichia coli having a gene encoding the fibroin-like protein in a medium, inducing expression of the gene encoding the fibroin-like protein, and collecting the fibroin-like protein, wherein accumulation of an organic acid at the time of inducing the expression is reduced, and wherein the gene is expressed under control of a tryptophan promoter.
