Analytically relevant neutral carrier membranes selective for K+, Ca2+, Na+, Ll+, and organic
cations respectively were studied. By applying an electrical potential gradient, a cation …

Folpet, N-(trichloromethylthio)-phthalimide and its metabolite phthalimide were determined
using an HPLC technique in fresh and fermented must and wine of Léon Millot grapes …

Folpet, N-(trichloromethylthio)-phthalimide, hydrolyzes in aqueous solutions to phthalimide,
carbon dioxide, hydrochloric acid, and sulfur. Using a slightly modified HPLC method, the …

During the past 2 years, yeasts present in a vineyard on grape were isolated and characterized
in Switzerland by physiological and molecular genetic methods. The taxonomy of some …

Microorganisms on grapes occur in so-called clusters. We have detected that the microflora
of such clusters on the root stock, on grape leaves, flowers, and buds differ with respect to …

The results are presented of investigations on microflora of grape in Switzerland in 1995 and
during wine production. Microorganisms (yeasts and moulds) occurred in "clusters" on the …

A brief review is given of the yeast species occurring in grape must and of methods for their
determination. The yeasts present in must from fungal-resistant grape cultivars which had …

The effect of different concentrations (0-20 LMR) of six pesticides on the aerobic growth of two
yeast strains (Saccharomyces cerevisiae, Metschnikowia pulcherrima) was analysed. The …

In this review the results obtained in the 1990s from research on the behavior of pesticide
residues on grapes, from treatment to harvest, and their fate in drying, wine-making, and …

Especially at the time then the leaves are harvested contact and systemic fungicides are
applied frequently to protect the grapevine against downy mildew and powdery mildew. …
