Contrast The photosynthetic or phototrophic bacteria can be broken into two major groups; the Anoxygenic Phototrophic Bacteria that grow under anaerobic conditions and theOxygenic PhototrophicBacteria that use oxygen to carry out photosynthesis

Subset  

 

Morphology Microcystis
CELLULAR  
Staining  
Morphology cells oval to spherical in diameter 3-8 um in diameter
Motility  
Specialized structures original isolates are amorpous aggeagates of cells with gas vesicles, held together by an amorphous "mucilagenous" sheath
Division binary fission is in 3 planes but the cells are irregularly oriented in aggregates
COLONIAL  
Solid surface  
Liquid

Products produce and excrete the toxic peptides microcystin and cyanoginosin

Beta-cyclocitral is also released which as an odour associated with old algal bllooms on lakes (Juttner, Z. 1984 Naturforsch. C. 39: 867-871)
