    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.

The dissimilation of calcium formate and lacetate, cellulose, amylose and sugars was investigated at temperatures above 55 °C. It was found that calcium formate and acetate were quantitatively fermented to C0 2 and CH 4 by thermophilic bacteria. All experiments were carried out with mixed cultures as it was impossible to obtain a pure culture of these bacteria. The thermophilic fermentation of cellulose, arnylose and sugars yielded calcium formate and acetate, CO 2 , H 2 , and sometimes CH 4 . A correlation between these two processes was, however, missing. Two isolated strains of the genus Bacillus were able to hydrolyze cellulose and arnylose but no fermentation was observed. Another strain of Bacillus fermented arnylose and sugars producing C0 2 , H 2 , and butyric, acetic and lactic acids. The thermophilic fermentation of plant residues leading to C0 2 and CH 4 was shown to proceed much more readily than the mesophilic process.
