    Details
    ISSN: 1432-072X

    Topics: Biology
    Notes: Abstract The Gram-positive methanogenic endosymbiont of the sapropelic ciliateMetopus striatus was isolated and identified asMethanobacterium formicicum. In the ciliate cell the methanogens are in close association with microbody-like organelles. No mitochondria could be detected. The nature of the microbodies and the physiological background of the observed association are discussed.

    Symbiosis of methanogenic bacteria and sapropelic protozoa (1983)
    Springer
    Archives of microbiology 136 (1983), S. 89-95 
    Details
    ISSN: 1432-072X
    Keywords: Coenzyme F420 ; Compound F342 ; Endosymbiosis ; Interspecies H2-transfer ; Methane production ; Methanogenic bacteria ; Metopus striatus ; Pelomyxa palustris ; Sapropelic protozoa-Urkaryotes
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Fluorescent bacteria were demonstrated to be abundantly spread as single cells throughout the cytoplasm of the giant amoeba Pelomyxa palustris, the sapropelic ciliate Metopus striatus and six other anaerobic protozoa examined. The endosymbionts of P. palustris and M. striatus were identified as methanogenic bacteria on the basis of the presence of the deazaflavin coenzyme F420 and the pterin compound F342. Moreover individuals of P. palustris produced methane over a long period of incubation. The number of methanogenic bacteria was above 1010 cells/ml protozoal cytoplasm. Two types of methanogenic bacteria together with unidentified thick bacteria were found in P. palustris. The physiological background of this endosymbiosis and its functioning in degradation processes in the anoxic environment are discussed.

    Description / Table of Contents: Samenvatting Na overenting op een medium dat tolchlofos-methyl bevatte, raakten enkele isolaten vanRhizoctonia solani gewend aan 500 maal de dosis die oorspronkelijk bijna alle groei verhinderde. Resistente isolaten vanR. solani bleven minder gevoelig voor tolchlofos-methyl na vijf overentingen op een medium zonder het fungicide. De pathogeniteit van resistente isolaten was niet verminderd, maar hun groeisnelheid op PDA was significant vertraagd vergeleken bij die van de oorspronkelijke isolaten. Isolatie van de resistente stammen werd niet verbeterd op een selectief medium waaraan tolchlofos-methyl was toegevoegd.
    Notes: Abstract Isolates ofRhizoctonia solani were adapted in vitro to grow on a medium amended with tolclofos-methyl at a concentration 500 times that which initially almost completely inhibited growth. Acquired resistance was retained after five transfers on a fungicide-free medium. Pathogenicity of resistant isolates was not reduced, but their growth rates on PDA were significantly lower than those of the original isolates. Recovery of the resistant isolates was not improved on a selective medium amended with tolclofos-methyl.

    Sweet potato stem blight caused by Alternaria sp.: A new disease in Ethiopia (1984)

    Description / Table of Contents: Samenvatting In 1977 werd een nieuwe ziekte ontdekt in zoete bataat in Ethiopië. De ziekte wordt gekenmerkt door zwarte necrotische lesies, voornamelijk op de stengels en bladstelen. Deze lesies breiden zich uit totdat de stengels en bladstelen omringd worden en de bovenliggende weefsels afsterven. De naam stengelnecrose wordt voorgesteld. De ziekte wordt veroorzaakt door eenAlternaria soort, waarvoor nog geen definitieve naam gevonden is. Het zou een nog onbeschreven soort kunnen zijn. Zoete bataat was het meest vatbaar, tomaat matig vatbaar, en netmeloen en spaanse peper waren resistent. Doornappel en ui vertoonden wel symptomen, maarAlternaria sp. kon niet uit het zieke weefsel worden geïsoleerd. Hoewel geen van de getoetste zoete bataatvariëteiten onvatbaar waren, waren er significante verschillen in gevoeligheid.
    Notes: Abstract A new sweet potato disease was discovered in Ethiopia. The disease mainly affects the stems and petioles of sweet potato and the name sweet potato stem blight is proposed. The pathogen is a species ofAlternaria, for which no definite name has been found so far. Sweet potatoes were most susceptible, tomatoes were slightly susceptible, and muskmelons and chilli peppers were resistant. Thorn apples and onions showed slight to moderate symptoms, butAlternaria was not reisolated from these two species. Although all sweet potato varieties tested were susceptible, there were significant differences in sensitivity.

    Der Werkstück-Oberflächenschutz im Fabrikationsablauf des Maschinenbaus (1955)

    Description / Table of Contents: Surface Protection of Work Pieces in the Manufacturing Prozesses of Mechanical EngineeringUnprotected surfaces of work pieces especially coarse surfaces of cast iron are usually rusting and contaminating easily.Their cleaning is as well most difficult as expensive for under these conditions really clean surfaces scarcely can be obtained.The costs for varnishing depend on the adhesiveness of the first coat of paint. Economical painting-methods can rarely be applied to work pieces if these are mechanically worked upon already.Therefore early surface protection of cast iron can be of great advantage as the charges for surface cleaning are decreased and the endurance of the coat of paint is improved. It also helps to improve cleanliness and hygiene of work.Two examples show the procedure and the advantage of ground-coating in the manufacturing prozesses of mechanical engineering.
    Notes: Ungeschützte Werkstückoberflächen setzen in der Regel Rost an und verunreinigen schnell, insbesondere dort, wo es sich um rauhe Gußoberflächen handelt. Die Reinigung ist dann meist schwierig und auch teuer. Wirklich saubere Oberflächen werden aber auch dann nur selten erzielt.Mit dem Haftvermögen des ersten Farbauftrages steht oder fällt der Aufwand für die Lackierung. In den Fällen, in denen die mechanische Bearbeitung des Stückes bereits erfolgte, ist die Benutzung rationeller Farbauftrags-Verfahren nur selten möglich. Ein frühzeitiger Oberflächenschutz des Gusses kann deshalb sehr vorteilhaft sein. Er senkt die Kosten für Oberflächenreinigung und erhöht die Haltbarkeit des Farbauftrages. Er verbessert außerdem die Arbeitshygiene und fördert die Sauberkeit im Betrieb.An zwei Beispielen werden der Aufwand und die Vorteile des Grundanstrichs im Fabrikationsablauf des Maschinenbaus aufgezeigt.
