Plant biostimulants - Determination of Enterococcaceae

This European Standard establishes the methodology for the determination of Enterococcaceae in plant biostimulant products in accordance to the future Regulation of EU fertilising products.

Pflanzen-Biostimulanzien - Bestimmung von Enterococcaceae

Dieses Verfahren wurde zur Bestimmung von Enterokokken in Biostimulanzien als einzelner Mikroorganismus-Bestandteil oder in einem Gemisch mit anderen Mikroorganismen entwickelt. Dieses Dokument ist nicht anwendbar auf mineralische Düngemittel, die als Ergänzungsfuttermittel festgelegt sind, hauptsächlich aus Mineralstoffen zusammengesetzt sind und mindestens 40 % Rohasche enthalten (Richtlinie 79/373/EWG) [3].

Biostimulants des végétaux - Détermination des Enterococcaceae

Cette méthodologie a été développée pour déterminer les entérocoques dans les biostimulants en tant que composant unique d’un microorganisme ou dans un mélange avec d’autres microorganismes. Le présent document ne s’applique pas aux engrais minéraux utilisés comme aliments complémentaires des animaux, principalement composés de minéraux et contenant au moins 40 % de cendres brutes (Directive du Conseil 79/373/CEE) [3].
