    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.

    Scale-down and optimization studies of the gluconic acid fermentation by Gluconobacter oxydans (1985)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 27 (1985), S. 711-720

    ISSN: 0006-3592

    Notes: To simulate production-scale conditions of gluconic acid fermentation by Gluconobacter oxydans, different experimental setups are presented in this study. From the determination of the time constants of a production-scale reactor, it can be concluded that mixing and oxygen transfer are the rate-limiting mechanisms. This results in oxygen concentration gradients which were simulated in a one-compartment reactor in which the oxygen concentration was fluctuated by a fluctuated gassing with air and nitrogen. It could be concluded that only very long periods of absence of oxygen (ca. 180 s) results in lower specific oxygen uptake rates by Gluconobacter oxydans. From scale-down studies carried out in a two-compartment system to simulate a production-scale reactor more accurately, it could be concluded that not only the residence time in the aerated part of the system is important, but the liquid flow in between the different parts of the reactor is also an essential parameter. It could also be concluded that the microorganisms are not influenced negatively by the fluctuated oxygen concentrations with respect to their maximal oxidation capacity. The two-compartment system can also be used for optimization experiments in which the “aerated” compartment was gassed with pure oxygen. From these experiments it was concluded that also a short residence of the cells at high oxygen concentrations diminished the growth and product formation rates. These experiments show the necessity of the scale-down experiments if optimization is carried out. The two-compartment system presented in this study is a very attractive tool for reliable scale-down experiments.

    Notes: Es wird gezeigt, daß Thionylbromid bei 520°±10° und Thionylchlorid bei 900°+10° in Schwefelmonoxyd und Halogen dissoziiert. Die Umsetzung zwischen Thionylbromid und verschiedenen Metallen verläuft ähnlich wie beim Thionylchlorid, nur im allgemeinen bei niedrigerer Temperatur. Bei der Umsetzung mit Silber wird jedoch kein Schwefelmonoxyd erhalten.

    Description / Table of Contents: First 1,4-Dipolar Cycloaddition Reactions of 3,6-Dihydro-6-oxo-1-pyrimidinium-4-olates to 1,2,4-Triazoline-3,5-dionesThe synthesis of some novel representatives of the pyrimidinium-4-olates of type 3 and 7, prepared from amidines 2 or 6 and bis(2,4,6-trichlorophenyl) malonates 1, is described. The representatives 3 or 7, which are substituted at the 5-position, react with the 1,2,4-triazoline-3,5-diones 4 even at room temperature to produce high yields of stable primary adducts 5 or 8, respectively, as a result of a 1,4-dipolar cycloaddition reaction, whereas the betaines 3i,j, which are unsubstituted at the 5-position, react with 4 to give the new betaines 9a,b.
