General description

Linden Grain Medium is a ready-mixed granulated high-quality alternative to powdered media. Its high nutrient creates optimum growth conditions for fungi and bacteria. The pH of the medium can be adjusted to the filling line criteria (as low as pH 4.1). Fungi and bacteria, which are adapted to grow under highly acidic conditions, show visible growth within 7 days of incubation at 28°C at a pH of 4.3. 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, flocculation of gas formation) or the surface of the medium, the inner walls, or bottom of the tubes /bottles indicates the presence of spoilage organisms.
Linden Grain Medium can be adjusted to other pH levels if needed. This culture medium could also be used after freezing and thawing, thus making it suitable for ice crusher installations.


Linden Grain Medium (base) is suitable for the detection of yeasts, molds, and bacteria in beverages. The medium is designed for media fill simulations of beverage bottling and ice crusher installations.
