Family OSCILLITORIA

DEFINITION OF OSCILLITORIA:-

Oscillatoria is a genus of filamentous cyanobacteria which is named for the oscillation in its movement. Filaments in the colonies can slide back and forth against each other until the whole mass is reoriented to its light source. It is commonly found in watering-troughs waters, and is mainly blue-green or brown-green. Oscillatoria is an organism that reproduces by fragmentation. Oscillatoria forms long filaments of cells which can break into fragments called hormogonia. The hormogonia can grow into a new, longer filament. Breaks in the filament usually occur where dead cells(necridia) are present. Oscillatoria uses photosynthesis to survive and reproduce.

ROLE OF OSCILLATORIA IN MARINE ENVIRONMENT:- ROLE IN NITROGEN FIXATION:-

Nitrogen fixation in marine Oscillatoria appears to be associated with differentiated cells located in the center of the colony. These central cells exhibit reduced pigmentation relative to peripherally located cells and do not incorporate 14CO2 in...
