Species of these organisms are numbered in the Pasteur culture collectionÂ
These organisms use the noncanonical amino acids BÂ·MÂ·AÂ·A and AÂ·DÂ·DÂ·A to make toxic microcystins ("micro"-SIS-tins). Species of these organisms are numbered in the Pasteur culture collectionÂ—for example, PCC 6803, which is a model organism. An icosahedral microcompartment first discovered in these organisms receives RuÂ·BÂ·P through a capsid-like shell and converts it to 3-phosphoÂ·glycerate. Stromatolites are biofilms composed mostly of these organisms. Lynn Margulis compared thylakoids to the carboxyÂ·somes and light-harvesting centers in this phylum. More than two billion years ago, these organisms caused the Great Oxygenation Event. Endosymbiosis predicts that chloroplasts originated as these organisms. For 10 points, name this phylum of photosynthetic bacteria o0en erroneously called blue-green algae.

cyanobacteria [or cyanobacterium; accept blue-green algae before "blue-green"; prompt on "bacteria" or "bacterium" or "prokaryotes"; do not accept or prompt on "algae"]
