New certified method: NordVal 063 Easy Plate YM-R for enumeration of yeasts and moulds
A NordVal International certificate valid until 14 Oct 2026 was issued to Kikkoman Biochemifa Company for Easy Plate YM-R for enumeration of yeasts and moulds in food, feed and environmental samples.
The method is a prepared microbiological culture device made up of a waterproof sheet, a dry medium on the sheet and a transparent cover over the medium. 1 ml volumes of appropriately diluted samples are plated onto the YM-R plates, allowed to soak in and then incubated. Yeasts tend to form small colonies with defined edges, and moulds tend to form colonies with diffuse edges.
