    Union Catalogue of Agricultural Libraries in the Netherlands

    The WUR Library Catalogue contains bibliographic data on books and periodicals held by the libraries of Wageningen University and Research Centre and some 15 associated libraries. Holding data are added to each record.

    Subjects covered include Agrotechnology, Food and Food Production, Plant and Animal Sciences, Soil Science, Geo-information, Landscape and Spatial Planning, Water and Climate, Ecosystem Studies, Economics and Society.

    The joint collections of the participating libraries cover a substantial part of the internationally available scientific literature in these disciplines.

    As far as Dutch scientific literature in these fields is concerned, coverage can be considered near 100%, including much of the so-called "grey literature".

    All titles are entered in their original language. Keywords are added to facilitate subject searching.

    The database is updated every day and now contains over 830.000 records.

Physical and biological investigations were carried out on the nitrogenous substances in the potato tuber. The importance of the potato as a food was considered in the introduction. By paper electrophoresis proteins in potato tuber sap could be separated into at least six fractions. The protein patterns were characteristic for the four potato varieties studied.

A study was made of the nitrogen and amino acid distribution of potato tubers and the influence of storage on it.

For assessment of the nutritive value of the crude protein fraction of the potato it was concluded that a microbiological assay with Terahymena pyrifermis W. was generally suitable as an index of biological value.

The nutritive value of the nitrogen of potato was not only dependent on amino acid composition of the protein but also largely on the free amino acids.
