The endosymbiotic origin of plastids from cyanobacteria gave eukaryotes photosynthetic capabilities and launched the diversification of countless forms of algae. These primary plastids are found in members of the eukaryotic supergroup Archaeplastida. All known archaeplastids still retain some form of primar...
Pigment analysis was performed on samples of whole, intact cells of the far-red cyanobacteria cultures enriched from the fronds of the brown macroalgae Stephanocystis osmundacea (sample A-19), which were centrifuged into pellets in growth medium, and stored at −80 °C in growth medium prior...
Many microalgae and cyanobacteria, in particular those living in the benthic zone, excrete large amounts of polymeric mucilage which cover their cells. In liquid culture, a minor fraction of the excreted polymers dissolve into the surrounding medium, whereas the majority of polymers remain attached ...
