TL;DR: It is found that the HT-58-2 culture is composed of the cyanobacterium and a community of associated bacteria, complicating the question of which organisms make tolyporphins, and an intriguing gene cluster that contains tetrapyrrole biosynthesis genes and a collection of unknown genes suggests a possible role in toly porphin biosynthesis.
