<Summary>For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.723587"! ** Semi-quantitative measures of the enzymes were determined in the samples using the apiZYM system (bioMerieux sa, Marey-l'Etoile, France). Values of 0-5 correspond to 0 to &gt; 40 nmol nitrophenyl released per 20 µl homogenate.</Summary>
