    Abstract: The present invention relates to a method for cultivating a microorganism, comprising the steps of



    (i) adding into a first bioreactor a medium and an inoculum comprising the microorganism and producing a fermentation broth in fed-batch culture; and
    (ii) adding into a second bioreactor a second medium and part of the fermentation broth from step (i) and producing a second fermentation broth in a second fed-batch culture; and
    (iii) adding into a next bioreactor a next medium and a part of the fermentation broth from step (ii), and producing a next fermentation broth in a next fed-batch culture,

    wherein a feed is introduced into the first, second and next bioreactor.
