Tumebacillus Soli
''Tumebacillus soli'' is a species of Gram positive, aerobic, bacterium. The cells are rod-shaped, motile, and form spores. It was first isolated from soil in Danghangpo, South Korea. The species was first described in 2015, and the name refers to its initial isolation from soil. The optimum growth temperature for ''T. soli'' is 37 °C, and can grow in the 25-45 °C range. Its optimum pH is 8.0, and grows in pH range 5.5-8.5. The bacterium forms cream-colored colonies on R2A agar R2A agar (Reasoner's 2A agar) is a culture medium developed to study bacteria which normally inhabit potable water. These bacteria tend to be slow-growing species and would quickly be suppressed by faster-growing species on a richer culture medium. ....

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...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. 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 Latin words for "tough skin," referring to the thick cell wall typical of bacteria in this phylum. Scientists once classified the Firmicutes to include all gram-positive bacteria, but have recently defined them to be of a core group of related forms called the low- G+C group, in contrast to the Actinomycetota. They have round cells, called cocci (singular coccus), or rod-like forms (bacillus). A few Firmicutes, such as ''Megasphaera'', ''Pectinatus'', ''Selenomonas'' and ''Zymophilus'', have a porous pseudo-outer membrane that causes them to stain gram-negative. Many Bacillota (Firmicutes) produce endospores, which are resistant to desiccation and can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacilli
Bacilli is a taxonomic class of bacteria that includes two orders, Bacillales and Lactobacillales, which contain several well-known pathogens such as ''Bacillus anthracis'' (the cause of anthrax). ''Bacilli'' are almost exclusively gram-positive bacteria. The name ''Bacillus'', capitalized and italicized, refers to a specific genus of bacteria. The name Bacilli, capitalized but not italicized, can also refer to a less specific taxonomic group of bacteria that includes two orders, one of which contains the genus ''Bacillus''. When the word is formatted with lowercase and not italicized, 'bacillus', it will most likely be referring to shape and not to the genus at all. Ambiguity Several related concepts make use of similar words, and the ambiguity can create considerable confusion. The term "''Bacillus''" (capitalized and italicized) is also the name of a genus (''Bacillus anthracis'') that, among many other genera, falls within the class Bacilli.

Bacillales
The Bacillales are an order of Gram-positive bacteria, placed within the Bacillota. Representative genera include ''Bacillus'', ''Listeria'' and ''Staphylococcus''. See also * List of bacteria genera * List of bacterial orders This article lists the orders of the Bacteria.

Alicyclobacillaceae
The Alicyclobacillaceae are a family of Gram-positive bacteria. All members of this family are aerobic and form endospores. The family contains four genera: ''Alicyclobacillus'', ''Effusibacillus'', '' Kyrpidia'', and '' Tumebacillus''. When originally created in 2009, Alicyclobacillaceae was a monophyletic family, only including genus ''Alicyclobacillus''. In 2011, the novel genus '' Kyrpidia'' was proposed and placed in family Alicyclobacillaceae, and '' Tumebacillus'' was placed into the family as well. In 2014, the novel genus ''Effusibacillus'' was proposed and added as the fourth member of Alicyclobacillaceae. ''Alicyclobacillus'' is the largest genus in Alicyclobacillaceae, with over 20 validly published species. The species are all acidophilic and have thermally resistant endospores. Many species are common soil organisms. Certain ''Alicyclobacillus'' species (especially '' A. acidoterrestris'') have been implicated in spoilage of pasteurized fruit juice. ''Effusibacill ...

Tumebacillus
''Tumebacillus'' is a genus of Gram-positive, rod-shaped, spore-forming bacteria. Members of the genus can be motile or non-motile, and form white or yellow colonies on R2A agar. The genus was first proposed in 2008 from the discovery of a potentially 5000-7000 year-old bacterium from Canadian high arctic permafrost, which would become the type strain of the genus '' T. permanentifrigoris''. The genus name was derived from Latin ''tume'' (from ''tumefacere'', to make swollen) and ''bacillus'' (small rod), referring to the swollen sporangia produced by ''T. permanentifrigoris'' and the shape of the cells. Members of this genus have been isolated from arctic permafrost, soil samples, cassava wastewater, decomposing algal scum, river water, and the gut of a vulture. ''Tumebacillus'' was found during surveys of nasal airways of infants, an underground subway in Norway, and a mountain observatory in Austria.

Gram Positive
In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall. Gram-positive bacteria take up the crystal violet stain used in the test, and then appear to be purple-coloured when seen through an optical microscope. This is because the thick peptidoglycan layer in the bacterial cell wall retains the stain after it is washed away from the rest of the sample, in the decolorization stage of the test. Conversely, gram-negative bacteria cannot retain the violet stain after the decolorization step; alcohol used in this stage degrades the outer membrane of gram-negative cells, making the cell wall more porous and incapable of retaining the crystal violet stain. Their peptidoglycan layer is much thinner and sandwiched between an inner cell membrane and a bacterial outer membrane, causing them to take up the counterstain (s ...

R2A Agar
R2A agar (Reasoner's 2A agar) is a culture medium developed to study bacteria which normally inhabit potable water. These bacteria tend to be slow-growing species and would quickly be suppressed by faster-growing species on a richer culture medium. Since its development in 1985, it has been found to allow the culturing of many other bacteria that will not readily grow on fuller, complex organic media.
