    Abstract Escherichia coli uses the C4-dicarboxylate transporter DcuA for L-aspartate/fumarate antiport, which results in the exploitation of L-aspartate for fumarate respiration under anaerobic conditions and for nitrogen assimilation under aerobic and anaerobic conditions. L-Aspartate represents a high-quality nitrogen source for assimilation. Nitrogen assimilation from L-aspartate required DcuA, and aspartase AspA to release ammonia. Ammonia is able to provide by established pathways the complete set of intracellular precursors (ammonia, L-aspartate, L-glutamate, and L-glutamine) for synthesizing amino acids, nucleotides, and amino sugars. AspA was regulated by a central regulator of nitrogen metabolism, GlnB. GlnB interacted with AspA and stimulated its L-aspartate deaminase activity (NH

    Abstract C4-dicarboxylates and the C4-dicarboxylic amino acid l-aspartate support aerobic and anaerobic growth of Escherichia coli and related bacteria. In aerobic growth, succinate, fumarate, D- and L-malate, L-aspartate, and L-tartrate are metabolized by the citric acid cycle and associated reactions. Because of the interruption of the citric acid cycle under anaerobic conditions, anaerobic metabolism of C4-dicarboxylates depends on fumarate reduction to succinate (fumarate respiration). In some related bacteria (e.g., Klebsiella), utilization of C4-dicarboxylates, such as tartrate, is independent of fumarate respiration and uses a Na+-dependent membrane-bound oxaloacetate decarboxylase. Uptake of the C4-dicarboxylates into the bacteria (and anaerobic export of succinate) is achieved under aerobic and anaerobic conditions by different sets of secondary transporters. Expression of the genes for C4-dicarboxylate metabolism is induced in the presence of external C4-dicarboxylates by the membrane-bound DcuS-DcuR two-component system. Noncommon C4-dicarboxylates like l-tartrate or D-malate are perceived by cytoplasmic one-component sensors/transcriptional regulators. This article describes the pathways of aerobic and anaerobic C4-dicarboxylate metabolism and their regulation. The citric acid cycle, fumarate respiration, and fumarate reductase are covered in other articles and discussed here only in the context of C4-dicarboxylate metabolism. Recent aspects of C4-dicarboxylate metabolism like transport, sensing, and regulation will be treated in more detail. This article is an updated version of an article published in 2004 in EcoSal Plus. The update includes new literature, but, in particular, the sections on the metabolism of noncommon C4-dicarboxylates and their regulation, on the DcuS-DcuR regulatory system, and on succinate production by engineered E. coli are largely revised or new.

    Title translation The own and the foreign in cross-cultural encounter - The naturalness of alienation
    Abstract Der vorliegende Artikel beschäftigt sich mit transkultureller Begegnung im Kontext der Psychotherapie und die dadurch naturgemäß entstehende Befremdung und dem Umgang mit dieser. Es wird betont, dass in der psychotherapeutischen Behandlung sowohl Behandelnde als auch Klienten ihren individuellen kulturellen Hintergrund mit in die Begegnung einbringen, dass hierbei gerade auch behandelnde Personen dazu neigen, sich mit Vorwissen zu "versorgen", um der Unsicherheit, die beim Kontakt mit "dem Fremden" entsteht, entgegenzuwirken, und dass diese Unsicherheit normal und natürlich ist. Es wird dafür plädiert, sich auf diese Unsicherheit einzulassen und Informationen zum Gegenüber nicht im Vorwissen, sondern im Kontakt mit diesem zu suchen.

    Abstract Biofilter werden in der Regel zur Minderung von Geruchsemissionen eingesetzt. Werden Biofilter ordnungsgemaess betrieben und Fehlerquellen waehrend des Betriebes ermittelt und behoben, koennen Geruchsbeeintraechtigungen aus diesem Betriebsbereich erfolgreich vermieden werden. Leider mussten bei von uns durchgefuehrten Messungen bei fast jedeom vierten Biofilter eine unzureichende Filterleistung beanstandet werden. Grund hierfuer ist hauptsaechlich die mangelhafte Eigenkontrolle der Betreiber. Der Biofilter wird im taeglichen Arbeitsablauf uebersehen. Durch geeignete Auflagen zur Kontrolle durch den Betreiber koennte bereits eine kontinuierlich gute Filterleistung gewaehrleistet werden. Erstmalige und wiederkehrende Messungen einer Messstelle fuehren in der Folgezeit zu einer befriedigenden Leistung der Biofilteranlagen. Weil in der Regel Messungen nur alle drei Jahre durchgefuehrt werden, sollte durch Kontrollen der betrieblichen Ueberwachung ein optimaler Betrieb gewaehrleistet werden.
