    Description

    Oxoid™ Orange Serum Agar is a specialized microbiological medium designed for the isolation, cultivation, and enumeration of acid‑tolerant microorganisms, particularly those associated with spoilage in citrus products. Its formulation incorporates orange serum, creating an acidic environment ideal for recovering organisms capable of surviving in fruit juices, concentrates, and related acidic matrices. 
    500 gm yields 13.5 L

     

    Key Features:

    Oxoid Orange Serum Agar works by providing:

    1. A Selective Low‑pH Environment

    The intrinsic low pH of orange serum restricts growth to acid‑tolerant organisms, including:

    • Lactic acid bacteria (e.g., Lactobacillus plantarum, L. brevis)
    • Leuconostoc species
    • Yeasts and moulds

    These organisms are commonly responsible for spoilage of citrus-based foods and beverages.

    2. Nutrient Components Supporting Optimal Recovery

    The medium contains:

    • Tryptone – supplying amino acids and nitrogenous compounds
    • Yeast extract – providing B‑complex vitamins and growth factors
    • Glucose – serving as an energy and fermentable carbohydrate source
    • Orange serum – enhancing recovery of acid-tolerant microorganisms

    3. Reliable Detection Through Proven Performance

    Comparative studies show Orange Serum Agar to be superior for total count and spoilage organism detection compared to other media designed for citrus spoilage organisms.

    Applications:

    • Citrus product quality control
    • Food Industry Microbiological Testing to assess Acid‑tolerant micro-organisms in fruit-derived foods
    • Acid‑tolerant microorganisms in fruit-derived foods 
    • Identify early-stage spoilage organisms
    • Validate sanitation processes
    • Support HACCP monitoring programs
    • Studying acid resistance mechanisms
    • Developing new citrus‑based or acidic products where microbial stability is critical
     

    Benefits:

    High Selectivity and Sensitivity

    -Its low pH environment and nutrient formulation allow precise detection of organisms that survive in acidic citrus matrices, improving confidence in spoilage assessments. 

    Proven Superior Performance
    -Backed by comparative studies demonstrating enhanced recovery compared to alternative media, making it a trusted choice for citrus-focused microbiology labs.

    Versatile Application Range

    -Ideal for:

    Routine QC
    Product development
    Environmental and packaging monitoring

    - Supports Fast, Accurate Enumeration

    Standard plate count methodology is easily applied, enabling:

    Rapid colony-forming unit (CFU) determination
    Reproducible microbial load tracking over time

    Easy Preparation and Standardized Performance

    Dehydrated form allows simple preparation and consistent batch‑to‑batch results, ensuring reliability in regulated laboratory environments.
