Plant biostimulants - Determination of the anaerobic plate count

This standard was developed to provide a horizontal method for enumeration of microorganisms that are able to grow and form colonies in a solid medium after anaerobic incubation at 30 °C, thereby verifying that they are not present in plant biostimulants (if the biostimulant itself is not anaerobic bacteria).

Pflanzen-Biostimulanzien - Bestimmung der anaeroben Keimzahl

Dieses Dokument stellt ein horizontales Verfahren zur Zählung von Mikroorganismen, die nach anaerober Bebrütung bei 30 °C in einem festen Medium wachsen und Kolonien bilden können, zur Verfügung.
Das Verfahren ist auf mikrobielle Pflanzen-Biostimulanzien anwendbar, ausgenommen jene, die aus aeroben Bakterien bestehen, um zu überprüfen, ob die Konzentration der Anaerobier die entsprechenden Grenzwerte der EU Düngeprodukteverordnung [1] nicht überschreitet.
Dieses Verfahren ist nicht anzuwenden für die mikrobiologische Überwachung der Umgebung, in der die mikrobiellen Pflanzen-Biostimulanzien hergestellt werden.
Es können keine Informationen über potentielle humanpathogene Keime aus der Auszählung der anaeroben koloniebildenden Einheiten abgeleitet werden.

Biostimulants des végétaux - Détermination du dénombrement sur plaque des germes anaérobies

Le présent document fournit une méthode horizontale pour le dénombrement des microorganismes qui sont capables de croître et de former des colonies dans un milieu solide après une incubation anaérobie à 30 °C.
La méthode est applicable aux biostimulants microbiens des végétaux, sauf ceux composés de bactéries aérobies,  pour vérifier que la concentration en anaérobies ne dépasse pas les limites correspondantes indiquées dans le Règlement UE sur les fertilisants [1].
La présente méthode ne s’applique pas à la surveillance microbiologique de l’environnement dans lequel les biostimulants microbiens des végétaux sont fabriqués.
Aucune information sur les pathogènes humains potentiels ne peut être déduite des dénombrements sur plaque des germes anaérobies.
