In response to environmental stress, cyanobacteria: synthesize nitrogen storage materials or show effects on nitrogen metabolism, synthesize new proteins or stop synthesizing some proteins, grow more slowly or rapidly, change pigment composition, excrete compounds or other enzymatic changes. These changes have been studied in order to implement the cyanobacteria as a bioremediation tool in the filamentous and unicellular cyanobacteria. Cyanobacteria, Nostoc muscorum and Synechococcus n natural wastes, using PS2 particles/thylakoids/spheroplasts.
