摘要： A method is described for producing a target substance utilizing a microorganism by culturing the microorganism in a medium to produce and accumulate the target substance in the medium, and then collecting the target substance from culture. The microorganism is imparted with isomaltase activity, or modified to increase isomaltase activity.

摘要： A method for producing a basic substance by fermentation comprising culturing a microorganism having an ability to produce the basic substance in a liquid medium contained in a fermentation tank to produce and accumulate the basic substance in the medium, wherein amount of sulfate and/or chloride ions used as counter ions of the basic substance is reduced by adjusting total ammonia concentration in the medium to be within a specific concentration range during at least a part of the total period of culture process.

摘要： A bacterium which belongs to the family Enterobacteriaceae, and has an ability to produce L-lysine, L-threonine, L-asparagine, L-aspartic acid, L-methionine, L-alanine, L-isoleucine, and/or L-homoserine. The bacterium has been modified so that expression of the gltP and/or gltS genes is/are increased when cultured in a medium, resulting in the accumulation of the L-amino acid(s) in the medium or bacterial cells.
