    • The invention relates to a process for the biosynthetic production of [5S,6S]-5,6-dihydroxy-cyclohexa-1,3-diene-1-carboxylic acid (2,3-trans-CHD) in an Escherichia microorganism having increased activity of isochorismate synthase and isochorismatase, and being deficient in activity of 2,3-dihydroxybenzoate synthase, wherein the process is carried out in a chorismate overproducing host microorganism also having decreased glucose dehydrogenase activity, or is carried out in a chorismate overproducing host microorganism naturally lacking glucose dehydrogenase activity. In this improved biosynthetic process, 2,3-trans-CHD is being produced in high yields and at concentrations in the biosynthetic reaction medium of at least 12 g/l. The invention further relates to the use of the supernatant of a process for the biosynthetic production of [5S,6S]-5,6-dihydroxy-cyclohexa-1,3-diene-1-carboxylic acid (2,3-trans-CHD) where the concentration of 2,3-trans-CHD in the process has arrived at a concentration of at least 12 g/l as a source for a co-factor for PQQ dependent enzymes.
    • 本发明涉及在具有增加的大肠杆菌中生物合成生产[5S,6S] -5,6-二羟基 - 环己-1,3-二烯-1-羧酸(2,3-反式-CHD)的方法 等位基因合成酶和异激酶活性,并且缺乏2,3-二羟基苯甲酸合成酶的活性,其中该方法在也具有降低的葡萄糖脱氢酶活性的过度生产的宿主微生物中进行,或者在过量产生宿主微生物的天竺葵中进行 缺乏葡萄糖脱氢酶活性。 在这种改进的生物合成过程中,以高产率和生物合成反应介质中的浓度产生至少12g / l的2,3-反式CHD。 本发明还涉及[5S,6S] -5,6-二羟基 - 环己-1,3-二烯-1-羧酸(2,3-反式-CHD)生物合成生产方法的上清液的用途 ),其中该过程中2,3-反式CHD的浓度已达到至少12g / l的浓度作为PQQ依赖性酶辅因子的来源。

    • 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.
