J G Zeikus, V G Bowen

    Canadian Journal of Microbiology
    |February 1, 1975
    PubMed
    Summary

    Methane-producing bacteria exhibit significant ultrastructural diversity, with distinct cell types identified. These methanogens show varied cell walls, inclusions, and membranes, indicating unique features across species.

    Area of Science:

    • Microbiology
    • Cell Biology

    Background:

    • Methanogenic archaea are crucial microorganisms in anaerobic environments.
    • Understanding their cellular diversity is key to comprehending their ecological roles.

    Purpose of the Study:

    • To investigate the ultrastructural diversity of methane-producing bacteria.
    • To classify methanogens based on fine structural and morphological characteristics.

    Main Methods:

    • Electron microscopy was employed for thin-section analysis.
    • Detailed examination of cell wall, inclusions, and internal membranes was performed.

    Main Results:

    • Methane-producing bacteria were found to be ultrastructurally diverse.
    • Four discrete cell types were identified based on fine structure.
    • Variations in Gram-positive cell walls, granular inclusions, reserve materials, and intracytoplasmic membranes were observed among cell types.
    • No unique ultrastructural features were common to all studied methanogenic species.

    Conclusions:

    • Methanogenic bacteria represent a diverse group at the ultrastructural level.
    • Distinct cell types with unique morphological characteristics exist within methanogens.
    • Further research into these variations can elucidate functional and evolutionary differences.
