    Notizen: [Auszug] We hold that the suggestion of MacCallum and Tanner is incorrect: equation (1) certainly has shortcomings, but they do not include the one proposed. Mathematically, the authors err in proceeding from the statement C - f(t,T) to the equation (3) Equation (3) is valid if and only if G is a state ...

    Modeling the specific growth rate of Lactobacillus plantarum in cucumber extract (1993)
    Springer
    Applied microbiology and biotechnology 40 (1993), S. 143-150 
    Details
    ISSN: 1432-0614
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Abstract Extensive empirical research has been published on the fermentation of vegetables, but little predictive modeling of the process is available. The objectives of this study were to assess the effects of key variables involved in cucumber fermentation and to develop models for predicting the growth of Lactobacillus plantarum in pure and mixed culture fermentations. The growth medium for the studies was cucumber juice. The effects of various concentrations of lactic, acetic, and hydochloric acids and sodium chloride on growth at 30° C were determined in batch culture. Limiting conditions for growth were pH 3.37 (lower limit), 69 mm undissociated lactic acid, 150 mm undissociated acetic acid, or 11.8% NaCl. Acetic acid was stimulatory to growth at low concentrations (up to 40 mm) but inhibitory at higher concentrations. Lactic acid was more inhibitory than acetic acid, whether total or undissociated concentrations were used as the basis of comparison. A predictive equation for specific growth rate was developed, tested, and shown to predict growth of L. plantarum in batch processes reasonably well.

    Modeling the cucumber fermentation: Growth ofLactobacillus plantarum (1993)
    Springer
    Journal of industrial microbiology and biotechnology 12 (1993), S. 341-345 
    Details
    ISSN: 1476-5535
    Schlagwort(e): Lactic acid bacteria ; Lactic acid ; Acetic acid ; Sodium chloride ; pH ; Hydrogen ion

    Notizen: Summary Specific growth rate models of product-inhibited cell growth exist but are rarely applied to fermentations beyond ethanol and large-scale antibiotic production. The present paper summarizes experimental data and the development of a model for growth of the commercially important bacterium,Lactobacillus plantarum, in cucumber juice. The model provides an excellent correlation of data for the influence on bacterial growth rate of NaCl, protons (H+), and the neutral, inhibitory forms of acetic acid and the fermentation product, lactic acid. The effects of each of the variables are first modeled separately using established functional forms and then combined in the final model formulation.

    Residence time distributions of paper pulp slurries in vertical laminar flow (1979)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 25 (1979), S. 131-143 
    Details
    ISSN: 0001-1541
    Schlagwort(e): Chemistry ; Chemical Engineering

    Thema: Chemie und Pharmazie , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: The hydrodynamic behavior of paper pulp slurries in vertical laminar flow has been observed and modeled. Radiotracers were used to tag both the liquid and solid phases of slurries flowing in 4 and 30 cm pipes. Residence time distributions were determined for each phase and were used to derive and compare several flow models. A model consisting of a central core in plug flow circumscribed by a clear Newtonian annulus provides a good representation of the observed slurry behavior. Correlations between the model parameters and the Reynolds number and slurry consistency are presented, and implications of the results on the design of slurry flow reactors are discussed.

    Benzoin- and benzoin methyl ether-sensitized photopolymerization of styrene and methyl methacrylate: Quantum yields and mixing effects (1975)

    Notizen: Styrene and methyl methacrylate have been polymerized in a batch photoreactor using two sensitizers-benzoin (C6H5COCHOHC6H5) and benzoin methyl ether (C6H5COCHOCH3C6H5)-and light with a peak intensity at 366 nm. Primary quantum yields have been calculated for each monomer-sensitizer combination. Effects of mixing on the rate of polymerization and product molecular weight distribution have been determined and correlated with a two-region reactor model.

    High gradient magnetic filtration of fine particles from a gas stream (1981)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 27 (1981), S. 193-202 
    Details
    ISSN: 0001-1541

    Thema: Chemie und Pharmazie , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Dust particles originally generated by two steelmaking processes were dispersed in an air stream and passed through a pilot-scale high gradient magnetic filter. In accordance with theoretical predictions, the experimental results showed that collection was improved by increasing the depth or density of the steel wool filter, increasing the applied magnetic field, or decreasing the filtration velocity. Collection efficiency increased with particle size up to about 2 μm, above which the efficiency tapered off, apparently due to reentrainment effects. Collection efficiencies of greater than 99% were obtained, indicating that high gradient magnetic filtration may be a practical method of controlling particulate emission from processes in the iron and steel industry.
