Content: They are ubiquitous, found in terrestrial, marine, and freshwater environments. Eukaryotic chloroplasts are thought to be derived from bacteria in this class. Prochlorococcus: Believed to be the most abundant photosynthetic organism on earth, it is responsible for generating half the world’s oxygen
Phormidium
Gram-positive Bacteria
Soil-dwelling members of this subgroup decompose organic matter. Some species cause disease. They have a thick cell wall and lack an outer membrane. Clostridium botulinum: Causes Botullism
Steptomyces: Many antibiotics, including streptomyocin, are derived from these bacteria
Mycoplasmas: These tiny bacteria, the smallest known, lack a cell wall.
