Anonychium
''Anonychium'' is a genus of plant in the pea family (Fabaceae). It includes a single species, ''Anonychium africanum'', a tree native to northern Sub-saharan Africa from Mauritania to Uganda and to Saudi Arabia. It is known by the synonym ''Prosopis africana'', and its common names include African mesquite, iron tree, ''gele'' (in Malinke), ''okpehe'', and ''somb'' tree. Okpehe is the name given by the Idoma and Igala people of Nigeria to both the tree and its fermented seeds. All of the other derivatives such as ''okpeye'' and ''okpiye'' stem from the noun ''okpehe'' used by the Idoma and Igala people of present day Benue State of Nigeria. In the Serer creation myth, it is one of the sacred trees that grew not just first, but also within the primordial swamp on Earth. Logs harvested from mature trees are one of the hardwoods used in crafting the shells of traditional djembes. Seeds of ''P. africana'' are used in Nigeria to prepare daddawa, kpaye, and okpeye, which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Condiment
A condiment is a preparation that is added to food, typically after cooking, to impart a specific Flavoring, flavor, to enhance the flavor, or to complement the dish. A table condiment or table sauce is more specifically a condiment that is served separately from the food and is added to taste by the diner. Condiments are sometimes added prior to serving, for example, in a sandwich made with ketchup, mustard (condiment), mustard or mayonnaise. Some condiments are used during cooking to add flavor or texture: barbecue sauce, compound butter, Teriyaki#Teriyaki sauce, teriyaki sauce, soy sauce, Marmite and sour cream are examples. Many condiments, such as mustard or ketchup, are available in Packet (container), single-serving packets, commonly when supplied with take-out or fast food meals. Definition The exact definition of a condiment varies. Some definitions encompass Spice, spices and Herb, herbs, including salt and pepper, using the term interchangeably with ''seasoning''. O ...

Trees Of Africa
In botany, a tree is a perennial plant with an elongated Plant stem, stem, or trunk (botany), trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller Arecaceae, palms, Cyatheales, tree ferns, Musa (genus), bananas, and bamboos are also trees. Trees are not a Taxon, taxonomic group but include a variety of plant species that Convergent evolution, have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has ...

Monotypic Fabaceae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...

Natural Gum
Natural gums are polysaccharides of natural origin, capable of causing a large increase in a solution's viscosity, even at small concentrations. They are mostly botanical gums, found in the woody elements of plants or in seed coatings. Human uses They are used in the food industry as thickening agents, gelling agents, emulsifying agents, and stabilizers, and in other industrial adhesives, binding agents, crystal inhibitors, clarifying agents, encapsulating agents, flocculating agents, swelling agents, foam stabilizers, etc. When consumed by humans, many of these gums are fermented by the microbes that inhabit the lower gastrointestinal tract (microbiome) and may influence the ecology and functions of these microscopic communities. Examples Natural gums can be classified according to their origin. They can also be classified as uncharged or ionic polymers (polyelectrolytes). Examples include (with E number E numbers ("E" stands for "Europe") are codes for substances used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enterotoxin
An enterotoxin is a protein exotoxin released by a microorganism that targets the intestines. Enterotoxins are chromosomally encoded or plasmid encoded exotoxins that are produced and secreted from several bacterial organisms. They are heat labile (>60⁰), and are of low molecular weight and water-soluble. Enterotoxins are frequently cytotoxic and kill cells by altering the apical membrane permeability of the mucosal (epithelial) cells of the intestinal wall. They are mostly pore-forming toxins (mostly chloride pores), secreted by bacteria, that assemble to form pores in cell membranes. This causes the cells to die. Clinical significance Enterotoxins have a particularly marked effect upon the gastrointestinal tract, causing traveler's diarrhea and food poisoning. The action of enterotoxins leads to increased chloride ion permeability of the apical membrane of intestinal mucosal cells. These membrane pores are activated either by increased cAMP or by increased calcium ion c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacillus Cereus
''Bacillus cereus'' is a Gram-positive rod-shaped bacterium commonly found in soil, food, and marine sponges. The specific name, ''cereus'', meaning "waxy" in Latin, refers to the appearance of colonies grown on blood agar. Some strains are harmful to humans and cause foodborne illness due to their spore-forming nature, while other strains can be beneficial as probiotics for animals, and even exhibit mutualism with certain plants. ''B. cereus'' bacteria may be anaerobes or facultative anaerobes, and like other members of the genus ''Bacillus'', can produce protective endospores. They have a wide range of virulence factors, including phospholipase C, cereulide, sphingomyelinase, metalloproteases, and cytotoxin K, many of which are regulated via quorum sensing. ''B. cereus'' strains exhibit flagellar motility. The ''Bacillus cereus'' group comprises seven closely related species: ''B. cereus'' ''sensu stricto'' (referred to herein as ''B. cereus''), '' B. ...

Bacillus Amyloliquefaciens
''Bacillus amyloliquefaciens'' is a species of bacterium in the genus ''Bacillus'' that is the source of the BamHI restriction enzyme. It also synthesizes a natural antibiotic protein barnase, a widely studied ribonuclease that forms a famously tight complex with its intracellular inhibitor barstar, and plantazolicin, an antibiotic with selective activity against ''Bacillus anthracis''. It is used in agriculture, aquaculture, and hydroponics to fight root pathogens such as ''Ralstonia solanacearum,'' ''Pythium'', ''Rhizoctonia solani'', ''Alternaria tenuissima'' and ''Fusarium'' as well improve root tolerance to salt stress. They are considered a growth-promoting rhizobacteria and have the ability to quickly colonize roots. Discovery and name ''Bacillus amyloliquefaciens'' was discovered in soil 1943 by a Japanese scientist named Fukumoto, who gave the bacterium its name because it produced (''faciens'') a liquifying (''lique'') amylase (''amylo''). Uses Alpha amylase from ''B. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micrococcus
''Micrococcus'' (mi’ krō kŏk’ Əs) is a genus of bacteria in the Micrococcaceae family. ''Micrococcus'' occurs in a wide range of environments, including water, dust, and soil. Micrococci have Gram-positive spherical cells ranging from about 0.5 to 3 micrometers in diameter and typically appear in tetrads. They are catalase positive, oxidase positive, indole negative and citrate negative. ''Micrococcus'' has a substantial cell wall, which may comprise as much as 50% of the cell mass. The genome of ''Micrococcus'' is rich in guanine and cytosine (GC), typically exhibiting 65 to 75% GC-content. Micrococci often carry plasmids (ranging from 1 to 100 MDa in size) that provide the organism with useful traits. Some species of ''Micrococcus'', such as ''M. luteus'' (yellow) and ''M. roseus'' (red) produce yellow or pink colonies when grown on mannitol salt agar. Isolates of ''M. luteus'' have been found to overproduce riboflavin when grown on toxic organic pollutants like pyridine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staphylococcus Epidermidis
''Staphylococcus epidermidis'' is a Gram-positive bacterium, and one of over 40 species belonging to the genus '' Staphylococcus''. It is part of the normal human microbiota, typically the skin microbiota, and less commonly the mucosal microbiota and also found in marine sponges. It is a facultative anaerobic bacteria. Although ''S. epidermidis'' is not usually pathogenic, patients with compromised immune systems are at risk of developing infection. These infections are generally hospital-acquired. ''S. epidermidis'' is a particular concern for people with catheters or other surgical implants because it is known to form biofilms that grow on these devices. Being part of the normal skin microbiota, ''S. epidermidis'' is a frequent contaminant of specimens sent to the diagnostic laboratory. Some strains of ''S. epidermidis'' are highly salt tolerant and commonly found in marine environment. S.I. Paul et al. (2021) isolated and identified salt tolerant strains of ''S. epiderm ...
