Abstract: The present invention relates to a process for integrated removal of one or more organic substances present in an aqueous bioprocess mixture, which comprise at least one positively charged and/or chargeable nitrogen-containing group, by means of reactive extraction in at least one step, in which process at least one liquid-liquid centrifuge is used for said reactive extraction and said organic substances are re-extracted from the extractant into an aqueous phase. More specifically, the bioprocess mixture directed to the liquid-liquid centrifuges is rendered cell-free and protein-free, before being directed into the first centrifuge. Furthermore, the invention relates to such a process in which an aqueous bioprocess mixture is continuously removed from a bioreactor, led, with an extractant, into a liquid-liquid centrifuge, extracted by means of said extractant, with an organic phase being obtained which contains the substance to be extracted from the fermentation mixture.
