Peptococcus
''Peptococcus'' is a Gram-positive bacterium genus in the family Peptococcaceae. Species in the genus are part of the human microbiome, especially in the bacteria that form the gut flora. They are part of the flora of the mouth, upper respiratory tract and large intestine. Mezlocillin is an antibiotic that is effective against ''Peptococcus'' species. '' Peptococcus niger'' is the only species left in the genus. All others have been moved to ''Peptostreptococcus''.

Desulforudis Audaxviator
''Candidatus Desulforudis audaxviator'' is a species of bacterium that lives in groundwater at depths from below the Earth's surface. The genus is monotypic taxon, monospecific. Etymology The name comes from a quotation from Jules Verne's novel ''Journey to the Center of the Earth,'' where the hero, Professor Lidenbrock, finds a secret inscription in Latin: ''Descende, audax viator, et terrestre centrum attinges'' (Descend, bold traveller, and you will attain the center of the Earth). Biology ''Desulforudis audaxviator'' is the only bacterium found in water samples obtained underground in the Mponeng Gold Mine in South Africa. Approximately four micrometres in length, it survives on chemical food sources derived from the radioactive decay of minerals in the surrounding rock. This makes it one of the few known organisms that does not depend on sunlight for nourishment, and the only species known to be alone in its ecosystem. It has genes for extracting carbon from carbon diox ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bacillota
The Bacillota (synonym Firmicutes) are a phylum of bacteria, most of which have Gram-positive cell wall structure. They have round cells, called cocci (singular coccus), or rod-like forms (bacillus). A few Bacillota, such as '' Megasphaera'', '' Pectinatus'', '' Selenomonas'', and '' Zymophilus'' from the class Negativicutes, have a porous pseudo-outer membrane that causes them to stain Gram-negative. Many Bacillota produce endospores, which are resistant to desiccation and can survive extreme conditions. They are found in various environments, and the group includes some notable pathogens. Those in one family, the Heliobacteria, produce energy through anoxygenic photosynthesis. Bacillota play an important role in beer, wine, and cider spoilage. Taxonomy The renaming of phyla such as Firmicutes in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature. The name "Firmicutes" was derived from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clostridia
The Clostridia are a highly polyphyletic class of Bacillota, including '' Clostridium'' and other similar genera. They are distinguished from the Bacilli by lacking aerobic respiration. They are obligate anaerobes and oxygen is toxic to them. Species of the class Clostridia are often but not always Gram-positive (see '' Halanaerobium'') and have the ability to form spores. Studies show they are not a monophyletic group, and their relationships are not entirely certain. Currently, most are placed in a single order called Clostridiales, but this is not a natural group and is likely to be redefined in the future. Most species of the genus ''Clostridium'' are saprophytic organisms that ferment plant polysaccharides and are found in many places in the environment, most notably the soil. However, the genus does contain some human pathogens (outlined below). The toxins produced by certain members of the genus ''Clostridium'' are among the most dangerous known. Examples are tetan ...

Genera
Genus (; : genera ) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demonstrate both monophyly and validity as a separate lineag ...
