    Ferredoxin of Cyanophora paradoxa Korsch. is encoded on cyanellar DNA (1989)

    Notes: Summary The ferredoxin present in the chloroplasts of higher plants and algae is encoded by the nuclear genome. We found that this is not the case for the cyanellar ferredoxin of Cyanophora paradoxa. The coding and synthesizing site of this polypeptide was determined by selective inhibition of transcription and translation in the host and the cyanellar compartment, respectively. Water-soluble cyanellar proteins were isolated, extracted from in vivo 14C-labelled cells, separated by NEPHGE and analyzed by autoradiography. The results clearly showed that the ferredoxin must be encoded on the cyanellar genome. This finding is discussed in the context of the evolutionary position of C. paradoxa cyanelles as a model system with which to study intermediate stages between cyanobacteria and plastids.

    Fatty acid analysis of four Azospirillum species reveals three groups (1988)
    Springer
    Archives of microbiology 149 (1988), S. 580-582 
    Details
    ISSN: 1432-072X
    Keywords: Cellular fatty acid composition ; Azospirillum lipoferum/brasilense ; Azospirillum halopraeferens ; Azospirillum amazonense ; Chemotaxonomy

    Topics: Biology
    Notes: Abstract Cellular fatty acid composition of 14 strains from the four species of Azospirillum was determined by gas chromatographic analysis. All strains of Azospirillum lipoferum and Azospirillum brasilense were similar in fatty acid data, thus not revealing an expected distinction between the two long established species. Strains of both Azospirillum halopraeferens and Azospirillum amazonense, however, differed significantly from this first group of strains.

    Van der Waals model for filled rubbers with modified interfacial contacts (1988)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 35 (1988), S. 345-362 
    Details
    ISSN: 0021-8995
    Keywords: Chemistry ; Polymer and Materials Science

    Notes: It is shown how the global deformation mechanism in filler-loaded vulcanizates were modified by additional filler-to-matrix bonds. A quantitative description is given in terms of an extended van der Waals treatment including the formulation of a reduced mechanical equation of state. An interpretation of the Mullins softening is presented.
