Bluegreen algae

The colorless sulfur-oxidizing microorganisms include relatives of the bluegreen algae (Beggiaioa and Thiothrix) and a genus of the eubac-teria (Thiobacillus). The latter require iron for growth and presumably synthesize the cytochrome systems (60).

It is now clear that among organisms there are two different organizational patterns of cells, which Chatton (1937) called, with singular prescience, the eucaryotic and procaryotic type. The distinctive property of bacteria and bluegreen algae is the procaryotic nature of their cells. [39]... 

Prokaryota, which comprise only bacteria and bluegreen algae, have no cell nucleus, which means that the DNA (desoxyribonucleic acid) is not covered by a nuclear membrane.
