Acidobacteria
Acidobacteriota is a phylum of Gram-negative bacteria. Its members are physiologically diverse and ubiquitous, especially in soils, but are under-represented in culture. Description Members of this phylum are physiologically diverse, and can be found in a variety of environments including soil, decomposing wood, hot springs, oceans, caves, and metal-contaminated soils. The members of this phylum are particularly abundant in soil habitats representing up to 52% of the total bacterial community. Environmental factors such as pH and nutrients have been seen to drive Acidobacteriota dynamics. Many Acidobacteriota are acidophilic, including the first described member of the phylum, ''Acidobacterium capsulatum''. Other notable species are ''Holophaga foetida'', '' Geothrix fermentans'', '' Acanthopleuribacter pedis'' and '' Bryobacter aggregatus''. Since they have only recently been discovered and the large majority have not been cultured, the ecology and metabolism of these bacteria i ...

Acidobacterium Capsulatum
''Acidobacterium capsulatum'' is a bacterium. It is an acidophilic chemoorganotrophic bacterium containing menaquinone. It is gram-negative, facultative anaerobic, mesophilic, non- spore-forming, capsulated, saccharolytic and rod-shaped. It is also motile by peritrichous flagella. Its type strain is JCM 7670. They can grow between pH 3.0 and 6.0, but not at pH 6.5. They give positive results in esculin hydrolysis, β-galactosidase and catalase tests and are negative in oxidase and urease tests. They can use glucose, starch, cellobiose, maltose as a sole carbon source, but cannot use elemental sulfur and ferrous iron as an energy source. Another characteristic of this organism is the presence of high amounts of exopolysaccharides coating the cells from soil isolates. Presence of exopolysaccharides helps in increased adhesion and allow the bacterium to acquire nutrients more readily from the environment. Ecology ''A. capsulatum'' are widely distributed in both aquatic and te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acanthopleuribacter Pedis
''Acanthopleuribacter pedis'' is a Gram-negative, rod-shaped bacterium found in marine environments. ''Acanthopleuribacter pedis'' is one of only two species of acidobacteria to have been isolated from animals. Colonies on marine agar are circular, smooth and yellow in color. ''Acanthopleuribacter pedis'' are found on marine agar at a temperature of 15–30 °C (optimally at 30 °C), and grows at a pH of 5–9 (optimally at pH 7–8). Etymology The etymology of the genus is: N.L. n.

Geothrix Fermentans
''Geothrix fermentans'' is a rod-shaped, anaerobic bacterium. It is about 0.1 µm in diameter and ranges from 2-3 µm in length. Cell arrangement occurs singly and in chains. ''Geothrix fermentans'' can normally be found in aquatic sediments such as in aquifers. As an anaerobic chemoorganotroph, this organism is best known for its ability to use electron acceptors Fe(III), as well as other high potential metals. It also uses a wide range of substrates as electron donors. Research on metal reduction by ''G. fermentans'' has contributed to understanding more about the geochemical cycling of metals in the environment. Taxonomy history ''Geothrix fermentans'' was isolated from metal-contaminated waters of an aquifer in 1999 by John D. Coates from Southern Illinois University and by others from the University of Massachusetts. The novel strain was originally named "Strain H-5T ". After classifying metabolism and confirming the presence and number of c-type cytochromes, Coat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gram-negative
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane. Gram-negative bacteria are found in virtually all environments on Earth that support life. The gram-negative bacteria include the model organism ''Escherichia coli'', as well as many pathogenic bacteria, such as ''Pseudomonas aeruginosa'', ''Chlamydia trachomatis'', and ''Yersinia pestis''. They are a significant medical challenge as their outer membrane protects them from many antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and lysozyme, an antimicrobial enzyme produced by animals that forms part of the innate immune system. Additionally, the outer leaflet of this membrane comprises a complex lipo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
