Orange Serum Agar is formulated to support the growth of acidophilic and acid-tolerant microorganisms found in fruit juices, beverages, citrus products, and other acidic foods. The medium contains enzymatic digests, glucose, and orange serum components that provide nutrients under low-pH conditions. It is widely used in food and beverage microbiology for detecting spoilage organisms.
Orange Serum Agar (catalogue No. 1307) is a dehydrated culture medium designed for the cultivation, isolation, and enumeration of acid-tolerant microorganisms, particularly those involved in spoilage of citrus products, fruit juices, soft drinks, and other acidic foods. The medium contains peptones, yeast extract, glucose, and dehydrated orange serum ingredients, providing essential nutrients even under acidic conditions where many organisms cannot grow.
This medium is used in routine quality-control laboratories to detect acidophilic bacteria, yeasts, and molds that may affect the stability and shelf-life of acidic beverages. It supports typical spoilage organisms such as Lactobacillus, Leuconostoc, and certain yeasts that thrive in low-pH environments.
Advantages
- Supports growth of acid-tolerant microorganisms related to spoilage of fruit juices and citrus products.
- Formulated to remain nutritionally active at low pH.
- Suitable for routine quality control in beverage and food microbiology.
- Easy preparation and consistent performance across acidic product testing.
