[Conditions for cyanobacteria L-transformation].

Area of Science:

• Microbiology
• Photosynthesis research

Background:

• Anabaena variabilis and Chlorogloea fritschii are cyanobacteria.
• These organisms can undergo L-transformation, altering colony morphology.

Purpose of the Study:

• To characterize the L-like colonies formed by Anabaena variabilis and Chlorogloea fritschii.
• To investigate the functional activity of the photosynthetic apparatus in these L-transformed organisms.

Main Methods:

• Morphological analysis of L-like colonies.
• Assessment of photosynthetic apparatus function.

Main Results:

• Anabaena variabilis and Chlorogloea fritschii form L-like colonies with distinct morphology.
• The colonies exhibit structures resembling those of chemoheterotrophic bacteria.
• Functional data of the photosynthetic apparatus in L-transformed states are presented.

Conclusions:

• Cyanobacteria can exhibit L-colony formation with bacterial-like morphology.
• L-transformation impacts the functional activity of the photosynthetic apparatus in these organisms.
