| Are not true by the composition of the nucleus of cells or cells in low single cell organisms in terms of relative to the eukaryotes. Generally do not have cell membrane, there is no nuclear membrane, but there is still genetic material, such as: DNA, RNA and so on. Prokaryotic DNA with little protein and ribosomes, and free form in the cytoplasm. |

| DNA is a long chain polymer composed of units called nucleotides, and sugar and phosphate molecules linked by ester bonds to form the long chain skeleton. Each sugar molecule with four bases in one of the phase, these bases are arranged along a long chain made of DNA sequences can be composed of the genetic code, is the basis for the synthesis of protein amino acid sequence. |

| This article is about phototrophism, obtaining energy from photosynthesis. For the tropism that governs growth toward or away from a light source, see Phototropism.A photolithotrophic autotroph is an autotrophic organism that uses light energy, and an inorganic electron donor (e.g., H2O, H2, H2S), and CO2 as its carbon source. Examples include plants. |

Biofilm cells and free cells have many different points:
Biofilm bacteria to antibiotics, hydrogen peroxide or detergent resistant than the free cells of up to 400 times higher.
By two-dimensional protein electrophoresis and found that bacteria in biofilms may be 40% and free cells express different proteins.
Biofilm bacteria can survive without the splitting of (sleep) a long time.
Biosynthesis in the biofilm polysaccharide secreted out more, and the different secondary metabolites.
The bacteria in the biofilm changes in the conditions of the external environment (such as pH, ion concentration, osmotic pressure, viscosity, nutrition, gas exchange) responses more quickly. |

Thermal Biology, or the majority may be referred to bacteria, is the relatively high temperatures (maximum 60 ℃) in the survival of life, this is a class of extremophiles. Many thermophilic organisms are Archaea.
On Earth, in many thermophilic organisms can be found in areas of geothermal activity, such as: Yellowstone National Park's hot springs, or deep sea hydrothermal vents.
To be able to survive under high temperature, thermophilic organisms at high temperatures can be maintained with active enzyme. Some enzymes of thermophilic bacteria can be used in molecular biology (such as heat stable DNA polymerase used for polymerase chain reaction, or in detergent. |

| Methanogens are microorganisms that produce methane as a metabolic byproduct in anoxic conditions. They are classified as archaea, a group quite distinct from bacteria. They are common in wetlands, where they are responsible for marsh gas, and in the guts of animals such as ruminants and humans, where they are responsible for the methane content of belching in ruminants and flatulence in humans.[1] In marine sediments biomethanation is generally confined to where sulfates are depleted, below the top layers.[2] Others are extremophiles, found in environments such as hot springs and submarine hydrothermal vents as well as in the "solid" rock of the Earth's crust, kilometers below the surface. |

| Halophiles are extremophile organisms that thrive in environments with very high concentrations of salt. The name comes from the Greek for "salt-loving". While the term is perhaps most often applied to some halophiles classified into the Archaea domain, there are also bacterial halophiles and some eukaryota, such as the alga Dunaliella salina. Some well-known species give off a red color from carotenoid compounds. Such species contain the photosynthetic pigment bacteriorhodopsin. Halophiles are categorized slight, moderate or extreme, by the extent of their halotolerance. Halophiles can be found anywhere with a concentration of salt five times greater than the salt concentration of the ocean, such as the Great Salt Lake in Utah, Owens Lake in California, the Dead Sea, and in evaporation ponds. |

| Syphilis is Treponema pallidum (pale spirochete, Treponema pallidum) of the bacteria that cause chronic diseases, the causative agents of Germany's Hoffman and Hsieh Wen set in 1905 first discovered, is a rendering soft, slender spirochetes, like metal shavings, Transparency is not easy due to staining, also known as white spiral. Syphilis is an anaerobic bacteria, soapy water can be short and general disinfectant to kill. Such bacteria invade the human body, usually on broken skin or mucous membrane, forming a characteristic primary lesions. After infection, the virus will quickly spread to the whole body, from the host cell to obtain mucopolysaccharide, and synthesis of N-acetylation of capsular-D-galactosamine, mucopolysaccharide was decomposed body cells, tissue damaged by injury, began to appear ulcer, almost all body organs, tissues spared, resulting in variable clinical features. |

| Anthrax [1] is caused by Bacillus anthracis acute infectious disease with high mortality, in 1850 discovered and confirmed by the French, and as a zoonotic disease. Symptoms of sick animals is a high-temperature fever, cramps, mouth and anal bleeding, chest, neck or abdominal swelling. Human infection, the occurrence of skin pustules, cough, spit, difficulty breathing, swelling of the spleen and other symptoms. |

| Smallpox is an infectious disease unique to humans, caused by either of two virus variants, Variola major and Variola minor.[1] The disease is also known by the Latin names Variola or Variola vera, which is a derivative of the Latin varius, meaning "spotted", or varus, meaning "pimple". The term "smallpox" was first used in Europe in the 15th century to distinguish variola from the "great pox" |

| Bioremediation is the use of microorganism metabolism to remove pollutants. Technologies can be generally classified as in situ or ex situ. In situ bioremediation involves treating the contaminated material at the site, while ex situ involves the removal of the contaminated material to be treated elsewhere. Some examples of bioremediation technologies are phytoremediation, bioventing, bioleaching, landfarming, bioreactor, composting, bioaugmentation, rhizofiltration, and biostimulation. |
