Sporosarcina Globispora
''Sporosarcina globispora'', formerly known as ''Bacillus globisporus'', is a Gram-positive, aerobic, round spore-forming bacillus. Strains of this species were originally described in 1967 and were found to be fairly similar to the species ''Bacillus pantothenticus''. The species was later reassigned to the genus '' Sporosarcina'' along with the species ''Bacillus psychrophilus'' and ''Bacillus pasteurii ''Sporosarcina pasteurii'' formerly known as ''Bacillus pasteurii'' from older taxonomies, is a gram positive bacterium with the ability to precipitate calcite and solidify sand given a calcium source and urea; through the process of microbio ...''.

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. The word "bacillus" (or its plur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Planococcaceae
The ''Caryophanaceae'' is a family of Gram-positive bacteria. In 2020, the now defunct family '' Planococcaceae'' was merged into ''Caryophanaceae'' to rectify a nomenclature anomaly. The type genus of this family is ''Caryophanon.'' The family ''Planococcacae'' was validly published in 1949, however it contained within it another family level taxonomic rank, the family ''Caryophanaceae,'' which was validly published in 1939. According to the International Code of Nomenclature of Prokaryotes (ICNP), the name ''Caryophanacaeae'' has higher priority than ''Planococcaceae'' because of its earlier publication. Therefore, the emended family retained the name ''Caryophanaceae''. The name ''Caryophanaceae'' is derived from the Latin term ''Caryophanon'', referring the type genus of the family and the suffix "-aceae", an ending used to denote a family. Together, ''Caryophanaceae'' refers to a family whose nomenclatural type is the genus ''Caryophanon''. Biochemical Characteristics an ...

Sporosarcina
''Sporosarcina'' is a genus of bacteria. Specification The cells of the species of ''Sporosarcina'' are either rod-shaped or coccoid. ''Sporosarcina'' forms endospores. The majority species of ''Sporosarcina'' is moveable (motile). Metabolism All species of ''Sporosarcina'' are heterotrophic. They do not perform photosynthesis. A few species are obligate aerobic, they need oxygen. Others are facultative aerobic, they can also perform metabolism in the absence of oxygen. Ecology Some species, such as ''S. ureae'' have the enzyme urease and are thus able to break down urea. The species forms the highest population densities in soils that are subject to influence of urine. These include, for example, meadows where cattle are kept. Thus ''S. ureae'' plays an important role in the ecosystem. Molecular Signatures Analyses of genome sequences of ''Sporosarcina'' species identified eight conserved signature indels (CSIs) that are uniquely present in this genus in the protein ...

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 (saf ...

Spore
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Two gametes fuse to form a zygote which develops into a new s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacillus
''Bacillus'' (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum ''Bacillota'', with 266 named species. The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural ''Bacilli'' is the name of the class of bacteria to which this genus belongs. ''Bacillus'' species can be either obligate aerobes which are dependent on oxygen, or facultative anaerobes which can survive in the absence of oxygen. Cultured ''Bacillus'' species test positive for the enzyme catalase if oxygen has been used or is present. ''Bacillus'' can reduce themselves to oval endospores and can remain in this dormant state for years. The endospore of one species from Morocco is reported to have survived being heated to 420 °C. Endospore formation is usually triggered by a lack of nutrients: the bacterium divides within its cell wall, and one side then engulfs the other. They are not true spores (i.e., not an offspring). Endospore formation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacillus Pasteurii
''Sporosarcina pasteurii'' formerly known as ''Bacillus pasteurii'' from older taxonomies, is a gram positive bacterium with the ability to precipitate calcite and solidify sand given a calcium source and urea; through the process of microbiologically induced calcite precipitation (MICP) or biological cementation. ''S. pasteurii'' has been proposed to be used as an ecologically sound biological construction material. Researchers studied the bacteria in conjunction with plastic and hard mineral; forming a material stronger than bone. It is a commonly used for MICP since it is non-pathogenic and is able to produce high amounts of the enzyme urease which hydrolyzes urea to carbonate and ammonia. Physiology ''S. pasteurii'' is a gram positive bacterium that is rod-like shaped in nature. It has the ability to form endospores in the right environmental conditions to enhance its survival, which is a characteristic of its bacillus class. It has dimensions of 0.5 to 1.2 microns in wi ...
