    Hottinger's blood agar is the best nutrient medium for cultivating fermentation-producing actinomyces, especially facultative anaerobes. A new liquid medium based on Hottinger's hydrolysate is also suitable for studying these microorganisms.

    Area of Science:

    • Microbiology
    • Biotechnology

    Context:

    • Actinomyces are crucial for fermentation processes.
    • Evaluating nutrient media is essential for their isolation and cultivation.
    • Previous research has not comprehensively assessed Soviet-manufactured media.

    Purpose:

    • To evaluate the fitness of various commercial nutrient media for isolating and cultivating fermentation-producing actinomyces.
    • To identify the optimal medium for both facultative anaerobic and anaerobic actinomyces.
    • To develop a new liquid medium for physiological studies.

    Summary:

    • Commercial nutrient media from the USSR were tested in two stages, using reference/isolated cultures and clinical materials.
    • Hottinger's blood agar demonstrated superior performance for facultative anaerobic actinomyces, showing high differentiating capacity.

  • This medium also supported anaerobic actinomyces growth when supplemented with meat extract. A novel liquid medium was developed using Hottinger's hydrolysate for physiological studies.

    • Impact:

    • Identifies the most effective commercial medium for actinomyces cultivation, improving research and industrial applications.
    • Provides a foundation for developing specialized media tailored to actinomyces.
    • Facilitates further research into the physiology of fermentation-producing actinomyces.
