Bacteria those need oxygen to survive ...

There are different groups of bacteria belonging to the same family and has evolved from the same bacteria (

ancestor). However, each species of bacteria have its own characteristics (those that developed after the separation from the primary species). Classification of bacteria: Bacteria are mainly classified by type (type is the scientific classification of organisms). For simplicity, bacteria can be divided into the following groups:

Bacteria classification based on the forms: as already mentioned, the appearance of DNA sequencing, bacteria were classified according to their shape and biochemical properties. Most bacteria belong to three main forms: rod (rod shape bacteria are called bacilli), sphere (sphere form bacteria called kokamy) and spiral (spiral bacteria called spirilla). Some bacteria belonging to the different forms that are more complex than the above forms. Aerobic and anaerobic bacteria: Bacteria are also classified based on the requirement of oxygen for their survival. Bacteria those need oxygen for survival are called Aerobic bacteria and bacteria those do not require oxygen to order strattera survive. Anaerobic bacteria can not carry oxygen and can die, if the oxygen environment (anaerobic bacteria found in places such as under ground, the depth of the ocean, and bacteria that live in certain environments). Gram-positive and gram-negative bacteria: Bacteria are grouped as "gram-positive" bacteria and "gram-negative" bacteria that are based on the results of Gram staining method (in which the agent is used for binding to bacterial cell wall) in bacteria. Autotrophic and heterotrophic bacteria: This is one of the most important types of classification, as it considers the most important aspect of bacteria growth and reproduction. Autotrophic bacteria (also known as autotrophs) to obtain carbon dioxide requires. Some autotrophs directly use sunlight to produce sugar from carbon dioxide, while others depend on various chemical reactions. Heterotrophic bacteria obtain carob and / or sugar among them (such as living cells or the body they are). .
