    摘要: A method for producing a desired protein, which comprises growing, by a fed-batch culture, a host cell capable of expressing the desired protein, wherein the specific growth rate of the host cell is changed from the initial rate to a predetermined one by successively changing the rate of addition of a substrate which controls the growth of the host cell. According to the mode of change of the rate of substrate addition to the medium of the present invention, optimal patterns of specific growth rate .mu. and specific production rate .rho. can be realized to optimize the fed-batch culture system. As a consequence of the realization, it is made possible to perform a high density culture of the host cell by fed-batch culture, an the desired protein can be produced efficiently in a short time.

    摘要: A production method of a heterologous protein, comprising culturing a heterologous protein-producing host prepared by gene manipulation in a medium containing a fatty acid or a salt thereof, and a surfactant and harvesting the heterologous protein from the culture. The production amount of the heterologous protein produced by a heterologous protein-producing host can be increased. Moreover, since decomposition of the heterologous protein by an enzyme derived from the host can be inhibited, enabling large scale production of a heterologous protein.
