[Ways to optimize the technological process of oleandomycin reextraction].

A A Slavin, E D Etingov, M V Ostrovskiĭ

    Antibiotiki
    |July 1, 1977

    Summary

    Optimizing oleandomycin extraction involves controlling pH and temperature. Performing extraction at pH 4.0-5.0 with decreased temperature enhances efficiency and reduces antibiotic inactivation.

    Area of Science:

    • Biochemistry
    • Chemical Engineering
    • Pharmacology

    Context:

    • Oleandomycin extraction is crucial for antibiotic production.
    • Butylacetate-water systems are commonly used for extraction.
    • Orthophosphoric acid is used for acidification.

    Purpose:

    • To study the dependence of the oleandomycin distribution coefficient on pH and temperature.
    • To optimize oleandomycin reextraction conditions.
    • To minimize antibiotic inactivation and organic solvent evaporation.

    Summary:

    • The study investigated how pH and temperature affect the oleandomycin distribution coefficient in a butylacetate-water system acidified with orthophosphoric acid.
    • Oleandomycin extraction was found to be most efficient at pH 4.0-5.0.
    • Simultaneously decreasing the temperature during extraction further improved efficiency and reduced degradation.

    Impact:

    • Provides optimized conditions for oleandomycin extraction.
    • Suggests methods to intensify the reextraction process.
    • Aims to reduce antibiotic loss and solvent evaporation during industrial processes.
