    Chemical properties of crystalline N-methylethyloxytetracycline (1963)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 5 (1963), S. 83-85 
    Details
    ISSN: 0006-3592
    Keywords: Chemistry ; Biochemistry and Biotechnology
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: The inclusion of ethionine in Streptomyces rimosus fermentation resulted in the production of N-methylethyloxytetracycline. The compound has been isolated, crystallized, and a number of its chemical properties determined.

    Resolution of complex wax ester mixtures by glass capillary GC (1980)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 3 (1980), S. 473-474 
    Details
    ISSN: 0935-6304
    Keywords: Gas chromatography ; Capillary, glass ; Complex wax ester mixtures ; Resolution of components by total carbon number and by degree of unsaturation ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: A glass capillary GC method providing high resolution analysis of complex wax ester mixtures is described. The two key parameters needed for evaluating a wax ester mixture for industrial utility - the total carbon chain length and the number of carbon-carbon double bonds present in each component - are simply and rapidly obtained by this method.

    Enzymatic brominatioin of the thiazole ring (1969)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 11 (1969), S. 1227-1232 
    Details
    ISSN: 0006-3592
    Keywords: Chemistry ; Biochemistry and Biotechnology
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Bromination of the thiazole ring by the enzyme chloroperoxidase, produced by the fungus Caldariomyces fumago, was demonstrated. Both 2-acetoacetamido-4-methylthiazole and 2-acetamidothiazole were brominated on C-5 of the thiazole ring in the presence of chloroperoxidase, bromide, and hydrogen peroxide in 0.06 M Phosphate solution at pH 3.0. No reaction occurred in the absence of enzyme.
