Scanning electron microscopy of bacteria Tetrasphaera duodecadis

Area of Science:

• Microbiology
• Bacteriology

Background:

• Tetrasphaera duodecadis is a bacterium requiring specific growth conditions.
• Understanding bacterial morphology is crucial for taxonomy and physiology.

Purpose of the Study:

• To characterize the morphological features of Tetrasphaera duodecadis bacteria.
• To observe morphological changes during different growth stages.

Main Methods:

• Cultivation of T. duodecadis in vitamin B12-supplemented broth.
• Scanning Electron Microscopy (SEM) for morphological evaluation.
• Turbidimetric method for bacterial concentration and growth curve determination.

Main Results:

• SEM revealed small agglomerates (0.8 ± 0.05 µm) during the lag phase.
• Rod-like shapes were observed during the exponential and stationary growth phases.
• Growth curve analysis provided data on bacterial concentration.

Conclusions:

• SEM is effective for visualizing T. duodecadis morphology.
• Distinct morphological changes occur throughout the bacterial growth cycle.
• This characterization provides a foundation for further T. duodecadis research.
