Abstract:
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.
