Description
Orange Serum Broth is a cultivation and enumeration medium for microorganisms associated with spoilage of citrus products.
Orange serum creates an acidic environment suited to acid-tolerant organisms, while tryptone, yeast extract and dextrose provide nutrients. The PDF also identifies use for saprophytic and pathogenic fungi and butyric-acid anaerobes.
Samples are inoculated into the broth and incubated at 30 ± 2°C for 18–48 hours. Turbidity indicates microbial growth.
