摘要:
According to the present invention, the E . coli mutant strain having chromosomal DNA that is at least 470 kbp shorter than that of a wild-type E . coli strain exhibits such a property that the number of the cells after a certain period of culture is greater than a wild-type strain. Thus, by culturing the mutant strain in a medium so as to generate and accumulate a useful substance in the culture, a useful substance such as proteins, peptides, amino acids, nucleic acids, vitamins, saccharides, organic acids, and lipids can be efficiently produced.
