Notizen: Summary Naphthylethylurea multiple-bonded chiral stationary phases prepared for the optimal resolution of p-bromophenylcarbamyl derivatives of enantiomeric amino acids are examined from the viewpoint of information theory. The criterion used is the function of mutual information (FUMI) which describes the precision of analysis as a function of peak shape (area and width), overlap and noise level. The length of the polyethyleneamine spacer in the chiral stationary phases is evaluated by the precision (FUMI) calculated from the peak shape and overlap. The best column is defined as the one which gives the highest precision. The temperature effect on the precision is also examined.

Notizen: The taxonomic status of various species of Dekkera, Brettanomyces and Eeniella was examined by electrophoretic comparison of enzymes, by deoxyribonucleic acid homology and by physiological characterization. These studies demonstrated that two teleomorphic Dekkera species, D. anomala and D. bruxellensis (Synonym. D. intermedia), and four anamorphic Brettanomyces species, B. anomalus (synonym B. claussenii), B. bruxellensis (synonym B. abstinens, B. custersii, B. Intermedius, B. lambicus), B. custersianus and B. naardenesis, can be recognized. The anamorphic genus Eeniella remained as a separate, monotypic taxon.
