    Area of Science:

    • Biochemistry
    • Microbiology
    • Cell Biology

    Background:

    • Traditional yeast homogenate preparation can be complex and time-consuming.
    • Efficiently lysing yeast cells is crucial for downstream molecular and enzymatic analyses.
    • Existing methods may require larger sample volumes or specialized equipment.

    Purpose of the Study:

    • To develop a simple, small-scale method for preparing yeast homogenate.
    • To optimize conditions for efficient yeast cell disruption and protein/enzyme release.
    • To evaluate the efficacy of the new method compared to existing techniques.

    Main Methods:

    • Utilized a tower-shaped mixer with glass beads to lyse yeast cells in suspension.
    • Investigated the effect of shaking time on cell breakdown and enzyme activity.
    • Processed small volumes (1 ml) of yeast cell suspension.
    • Simultaneously processed up to 14 samples under controlled conditions.

    Main Results:

    • Optimal cell breakdown and soluble protein liberation achieved at 20 minutes of shaking.
    • Enzyme activities in the prepared homogenate were equivalent to or higher than those from conventional methods.
    • The method demonstrated applicability across various yeast species.
    • High throughput processing of multiple samples was achieved.

    Conclusions:

    • The developed method offers a simple, efficient, and scalable approach for yeast homogenate preparation.
    • This technique facilitates robust downstream analysis of yeast enzymes and proteins.
    • The method is suitable for diverse research applications involving yeast.
