Linden Grain Medium has high nutrient content that creates optimum growth conditions for fungi and bacteria. The pH of the medium can be adjusted to the filling line criteria. At a pH of 4.3, fungi and bacteria which are adapted to grow under high acid conditions show visible growth within 7 days of incubation at 28°C. Bacteria that grow best at neutral to slightly alkaline pH, like Bacillus subtilis, show no growth/very limited growth in Linden Grain Medium at pH 4.3. Any growth within the medium (turbidity), on the surface of the medium, or the inner wall or bottom of the tubes and bottles indicates the presence of spoilage organisms. Experiments have shown that Linden Grain Medium could also be used after freezing and thawing, thus making this medium suitable for ice crusher installations.
Linden Grain Medium is suitable for the detection of yeasts, molds, and bacteria in beverages. It is designed for media fill simulations of beverage bottling and ice crusher installations.
