Scientific classification or biological classification refers to how biologists group and categorize extinct and living species of organisms. Modern classification has its roots in the system of Carolus Linnaeus, who grouped species according to shared physical characteristics. These groupings have been revised since Linnaeus to improve consistency with the Darwinian...

Division:
Classes Bacilli Clostridia Mollicutes The Firmicutes are a group of bacteria, most of which have Gram-positive stains. A few, the Mollicutes or mycoplasmas, lack cell walls altogether and so do not respond to Gram staining, but still lack the second membrane found in other Gram-negative forms. Originally the...

Class:
Orders Clostridiales Halanaerobiales Thermoanaerobacteriales The Clostridia are a group of Firmicutes, including Clostridium and other similar genera. They are distinguished from Bacilli by being obligate anaerobes, and do not appear to be a monophyletic group. Categories: Firmicutes | Bacteria stubs ...

Acidaminococcaceae Clostridiaceae Eubacteriaceae Genera Heliobacterium Heliobacillus Heliophilum Heliorestis The heliobacteria are a small family of bacteria that produce energy through photosynthesis. The primary pigment involved is bacteriochlorophyll g, which is unique to the group and absorbs at different frequencies than other photosynthetic pigments, giving the heliobacteria their own environmental niche. Photosynthesis takes place...
