They obtain their energy from the sun as well as from organic and inorganic molecules, and as per that they are classified as Photosynthetic autotrophs (use energy from the sun to produce their own carbohydrates for energy), Chemosynthetic autotrophs (process inorganic molecules for energy (example: sulfur or iron) and heterotrophs (depend on outside sources of organic molecules (example: carbohydrates or sugars) for energy. In this vast living world, having a system of naming and grouping bacteria and other micro-organisms becomes a necessity and hence we have Classification and Nomenclature to maintain clarity and avoid any confusion. Mesophiles: Those bacteria that can grow best between (25-40)C but optimum temperature for growth is 37C. The bacterial classification is one of the key factors to tackle them in disease. They are in various shapes likely bacillus (rod), coccus (spherical), spirillum (spiral), vibrio (curved rod). They reproduce by bipartition and are capable of donating and receiving genetic material through transformation, transduction or conjugation.
