    Description / Table of Contents: Zusammenfassung Gegen den Pilz Trametes versicolor (Isolierung D4) wurde ein Antiserum entwickelt. Die Untersuchungen wurden mit der Agar-gel-Doppelt-diffusionsmethode ausgeführt und zeigten zum mindesten acht antigenische Komponenten in den Pilzen. Einige Antigene, die identisch zu denen in D4 sind, wurden in den anderen verwandten Pilzen entdeckt. Es wurden die beiden Arten des antiserums geprüft: das absorbierende und das nichtabsorbierende. Im ganzen scheinen sich die serologischen Daten mit der konventionellen Klassifizierung zu decken und so wird vorgeschlagen, daß man die serologische Methode gut zur Identifizierung verschiedener Trametes-Gattungen anwenden könnte.
    Notes: Summary An antiserum against Trametes versicolor isolate D4 has been developed. The use of agar-gel double-diffusion tests has revealed at least eight antigenic components in the fungus. Some antigens identical to those of D4 have been detected in other related fungi using both unabsorbed and absorbed antiserum. The overall serological data seem to agree with the conventional classification of these fungi and it is suggested that serological methods may be useful in identifying various Trametes species.

    Description / Table of Contents: Zusammenfassung Die gestielte Bakteriengattung der Hyphomikroben wird für die Manganschlammablagerungen in Süßwasserdruckrohrleitungen verantwortlich gemacht. Die Bindung der Zellen an die Rohroberfläche soll durch elektrostatische Anziehungskraft und Bildung von Haftmaterial bewirkt werden. Die elektrophoretischen Versuche zeigen, daß die Hyphomicrobium-Zellen negativ geladen und die Ionen-Gruppen der Oberfläche Carboxyle sind. Es wird postuliert, daß die eigentümliche Morphologie und Vermehrungsweise der Hyphomikroben verantwortlich sind für ihre Fähigkeit, Manganoxyde zu bilden und mit ihnen gemeinsam zu existieren.
    Notes: Summary Stalked, budding bacteria of the genus Hyphomicrobium are shown to be responsible for manganese deposition in freshwater pipelines. The attachment of the cells to the pipe surface is considered from the point of view of electrostatic attraction and the production of holdfast material. Electrophoretic studies indicate that Hyphomicrobium cells are negatively charged and that their surface ionogenic groups are carboxylic. It is postulated that the curious morphology and mode of reproduction of hyphomicrobia accounts for their efficiency in producing, or coexisting with, the manganese oxides they produce.

    Notes: [Auszug] Neurones of the ventral group of nuclei of the feline thalamus are among those reported to be stimulated both by the excitatory amino-acids and by ACh (for example, refs. 4 and 5). We have compared the actions of three acids and of ACh on cells lying in vertical tracks through the thalamus between ...

    Notes: Abstract d-Serine (0.05m) inhibited nitrification byAspergillus flavus in media containing either peptone, aspartate,a-alanine or β-alanine as the sole nitrogen source. A similar inhibition was observed in an aspartate + peptone medium, but nitrate was formed in a β-alanine + peptone medium in the presence of the inhibitor. Exceptionally high yields of nitrate were obtained in the β-alanine + peptone medium. In replacement cultures,d-serine inhibited nitrification of aspartate but not of β-alanine. Manometric studies indicated that aspartate was decarboxylated byA. flavus and that the reaction was inhibited byd-serine. In view of these results, it is suggested that aspartate is a precursor and β -alanine is an intermediate in nitrification by this fungus.

    Notes: Abstract Evidence is presented that stalked, budding bacteria (hyphomicrobia) are responsible for the deposition of manganese in certain freshwater pipelines in Tasmania. Laboratory-scale equipment is described which allows manganese oxidation to be studied under controlled conditions. In some pipelines the lack of deposition is due to insufficient manganese in the lake water and not to absence of the appropriate hyphomicrobia. The composition of the pipeline deposits in Tasmania and other parts of the world are strikingly similar, and it is suggested that hyphomicrobia occur in manganese deposits more frequently than has been recorded.
