    • 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. Said substance may be re-extracted in a cycle via a second liquid-liquid centrifuge, resulting subsequently in a concentrated aqueous solution of the extracted substance, and the organic phase being recycled into the first liquid-liquid centrifuge.

    • A process for the removal of ammonium from aqueous liquids, especially from fermentation broths, is disclosed. The process uses a cation exchanger membrane which separates a liquid on a donor side that is to be depleted of NH.sub.4.sup.+ from a solution on an acceptor side whose pH is higher than on the donor side. Because of the equilibriumNH.sub.4.sup.+ .revreaction.NH.sub.3 +H+there is on the acceptor side increased formation of NH.sub.3. This is continuously removed, in particular by reducing the pressure and/or passing through inert gas, or by selective transport through another microporous membrane into an acid protonation solution, so that a NH.sub.4.sup.+ concentration gradient is maintained across the membrane. A similar content, apart from the ammonium concentration, of concomitant cations on the donor and acceptor side and/or a high ratio of the solution volumes on the donor side and the acceptor side ensures that the solution on the donor side to be depleted of NH.sub.4.sup.+, does not lose concomitant ions. A suitable apparatus comprises a flow section which can be coupled into a bypass and has a cation exchanger limiting membrane which is simultaneously a limiting wall of an acceptor chamber. The acceptor chamber may contain devices for pH control and NH.sub.3 removal or these may be contained in a flow section.

    • A peptide amidase isolated from the flavedo of citrus fruits, preferably oranges, which is capable of catalyzing the selective hydrolytic elimination of the free amino group on the C-terminal end of peptide amides but which does not cleave peptide bonds. The enzyme accepts D-amino acid residues in the C-terminal position, although the hydrolysis rate is much slower than with L-amino acid residues. The enzyme is weakly inhibited by serine protease inhibitors; has an optimal pH of 7.5.+-.1.5, an optimum temperature of 30.degree. C. at pH 7.5 and has an isoelectric point of pH 9.5. The peptide amidase is stable at pH 6.0-9.0. The molecular weight of the purified enzyme is 32,000.+-.3000 daltons. A peptide amidase according to the present invention is particularly useful in the production of peptides by continuous enzymatic reaction of N-protected amino acid or peptide alkyl esters with amides of amino acids. In the continuous reaction, the synthesized peptide amide is hydrolyzed by the peptide amidase and separated by anion exchange from the amide of the amino acid which can be recycled.
