Co-contributors and advisors: Hong Cui (University of Arizona), Lisa Moore (University of Southern Maine), and Ramona Walls (University of Arizona). MicrO (An Ontology of Prokaryotic Phenotypic and Metabolic Characters). Version 1.5.1 released 6/14/2018. Includes terms and term synonyms extracted from > 3000 prokaryotic taxonomic descriptions, collected from a large number of taxonomic descriptions from Archaea, Cyanobacteria, Bacteroidetes, Firmicutes and Mollicutes. The ontology and the synonym lists were developed to facilitate the automated extraction of phenotypic data and character states from prokaryotic taxonomic descriptions using a natural language processing algorithm (MicroPIE). MicroPIE was developed by Hong Cui, Elvis Hsin-Hui Wu, and Jin Mao (University of Arizona) in collaboration with Carrine E. Blank (University of Montana) and Lisa R. Moore (University of Southern Maine). Descriptions and links to MicroPIE can be found at http://avatol.org/ngp/nlp/overview-2/. https://github.com/biosemantics/micropie2 The most current version of MicrO can be downloaded from https://github.com/carrineblank/MicrO.

Carrine Blank has ingredient Relationship between a material entity (x), which is a man-made material entity such as a chemical solution or a culture medium, and a chemical entity (y), where the chemical entity forms part of a mixture of chemicals that make up the material entity. Carrine Blank Wikipedia:ingredient An ingredient is a substance that forms part of a mixture (in a general sense). For example, in cooking, recipes specify which ingredients are used to prepare a specific dish. Many commercial products contain a secret ingredient that is purported to make them better than competing products. In the pharmaceutical industry, an active ingredient is that part of a formulation that yields the effect required by the customer. National laws usually require prepared food products to display a list of ingredients, and specifically require that certain additives be listed. In most developed countries, the law requires that ingredients be listed according to their relative weight[1] in the product. If an ingredient itself consists of more than one ingredient (such as the cookie pieces which are a part of "cookies and cream" flavor ice cream), then that ingredient is listed by what percentage of the total product it occupies, with its own ingredients displayed next to it in brackets. The term constituent is often chosen when referring to the substances that constitute the tissue of living beings such as plants and people, because the word ingredient in many minds connotes a sense of human agency (that is, something that a person combines with other substances), whereas the natural products present in living beings were not added by any human agency but rather occurred naturally ("a plant doesn't have ingredients"). Thus all ingredients are constituents, but not all constituents are ingredients. is an ingredient of Relationship between a chemical entity (x) and a mixture, culture medium, or chemical solution (y), where y is artificial created by human activity.

Epiphytes differ from parasites in that epiphytes grow on other plants for physical support and do not necessarily negatively affect the host. An epiphytic organism that is not a plant is called an epibiont.[1] Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads).[2] Many houseplants are epiphyte species due to their minimal water and soil requirements. Epiphytes provide a rich and diverse habitat for other organisms including animals, fungi, bacteria, and myxomycetes.[3] Carrine Blank An environment that exists on a terrestrial plant (Embryophyte). epiphytic endophytic environment An environment that exists within a plant (Embryophyte). Carrine Blank endophytic Wikipedia: Endophyte An endophyte is an endosymbiont, often a bacterium or fungus, that lives within a plant for at least part of its life cycle without causing apparent disease.[1][2][3][4] Endophytes are ubiquitous and have been found in all species of plants studied to date; however, most of these endophyte/plant relationships are not well understood.[5][6] Endophytes are also known to occur within lichens[7] and algae. Many economically important grasses (e.g., Festuca spp. and Lolium spp. ) carry fungal endophytes in genus Epichloë,[8] some of which may enhance host growth[9] and may improve the plant's ability to tolerate abiotic stresses, such as drought, and enhance resistance to insects, plant pathogens and mammalian herbivores.[10][11][12][13] lives inside a plant periphytic environment periphytic Carrine Blank periphytically An environmental system that is submerged, and attached to submerged rocks, plants, animals, or other objects. calyptra Modified apical cell, having a thickened or enlarged morphology.

Principles of the Procedure Enzymatic digests of casein and soybean provide amino acids and other complex nitrogenous substances. Dextrose is an energy source. Sodium chloride maintains the osmotic equilibrium. Dibasic potassium phosphate acts as a buffer to control pH. The addition of 6.5% sodium chloride to Trypticase Soy Broth permits the differentiation of salt-tolerant enterococci, which are resistant to the high salt content, from the salt-intolerant S. bovis group and other streptococcal species. At this concentration, the sodium chloride is a selective agent that interferes with membrane permeability and osmotic and electrokinetic equilibria.4 Fildes Enrichment is a peptic digest of sheep blood that supplies the X (hemin) and V (nicotinamide adenine dinucleotide, NAD) factors necessary for the growth of H. influenzae. Dextrose is omitted from the formula for Tryptic Soy Broth without Dextrose to permit use of the medium in fermentation studies. The carbohydrate concentration used most frequently in fermentation reactions is 0.5% or 1%. Tryptic Soy Broth and Trypticase Soy Broth are provided as prepared media in a variety of bottle styles. In addition, Tryptic Soy Broth is provided as a Sterile Pack Bottle; i.e., the bottle has been terminally sterilized inside of autoclavable double-bags.

Delineates prokaryotes into two major groups (Gram positive and Gram negative, although results can be ambiguous in some taxa) that results from the different staining of cell wall types. Wikipedia:Gram_staining Gram staining, also called Gram's method, is a method of differentiating bacterial species into two large groups (gram-positive and gram-negative). The name comes from the Danish bacteriologist Hans Christian Gram, who developed the technique. Gram staining differentiates bacteria by the chemical and physical properties of their cell walls by detecting peptidoglycan, which is present in a thick layer in gram-positive bacteria.[1] In a Gram stain test, gram-positive bacteria retain the crystal violet dye, while a counterstain (commonly safranin or fuchsine) added after the crystal violet gives all Gram-negative bacteria a red or pink coloring.

Used for the growth of Streptoalloteichus. endospore Carrine Blank sporulating spore-forming From Wikipedia:endospore: An endospore is a dormant, tough, and non-reproductive structure produced by certain bacteria from the Firmicute phylum. The name "endospore" is suggestive of a spore or seed-like form (endo means within), but it is not a true spore (i.e., not an offspring). It is a stripped-down, dormant form to which the bacterium can reduce itself. Endospore formation is usually triggered by a lack of nutrients, and usually occurs in Gram-positive bacteria. In endospore formation, the bacterium divides within its cell wall. One side then engulfs the other. Endospores enable bacteria to lie dormant for extended periods, even centuries. Revival of spores millions of years old has been claimed. When the environment becomes more favorable, the endospore can reactivate itself to the vegetative state. Most types of bacteria cannot change to the endospore form. Examples of bacteria that can form endospores include Bacillus and Clostridium. A differentiated prokaryotic cell, found in the Firmicutes, which is specialized for extreme tolerance to desiccation, radiation, and exposure to ultraviolet light. Characterized by thick cell walls. spore-former gas vacuole Wikipedia:bacterial_cell_structure Gas vacuoles are membrane-bound, spindle-shaped vesicles, found in some planktonic bacteria and Cyanobacteria, that provides buoyancy to these cells by decreasing their overall cell density. Positive buoyancy is needed to keep the cells in the upper reaches of the water column, so that they can continue to perform photosynthesis. They are made up of a shell of protein that has a highly hydrophobic inner surface, making it impermeable to water (and stopping water vapour from condensing inside) but permeable to most gases. Because the gas vesicle is a hollow cylinder, it is liable to collapse when the surrounding pressure becomes too great. aerotopes gas vesicles vacuolized gas vacuole gas-vacuolated An intracellular non-membran-bound organelle (cytoplasmic vesicle) made of protein which functions to provide buoyancy to the cell in the water column.

They contain 15 to 20 magnetite crystals that together act like a compass needle to orient magnetotactic bacteria in geomagnetic fields, thereby simplifying their search for their preferred microaerophilic environments. Each magnetite crystal within a magnetosome is surrounded by a lipid bilayer, and specific soluble and transmembrane proteins are sorted to the membrane. Recent research has shown that magnetosomes are invaginations of the inner membrane and not freestanding vesicles. Magnetite-bearing magnetosomes have also been found in eukaryotic magnetotactic algae, with each cell containing several thousand crystals.

A multicellular relationship of prokaryotic cells where the shape of the cell is elongated (forming a bacillus, or short rod) and the cells are attached to one another end-to-end to form chains. streptobacilli Carrine Blank streptococcus Wikipedia:Streptococcus Streptococcus is a genus of spherical Gram-positive bacteria belonging to the phylum Firmicutes and the lactic acid bacteria group. Cellular division occurs along a single axis in these bacteria, and thus they grow in chains or pairs, hence the name—from Greek στρεπτος streptos, meaning easily bent or twisted, like a chain (twisted chain). Contrast this with staphylococci, which divide along multiple axes and generate grape-like clusters of cells. Most streptococci are oxidase- and catalase-negative, and many are facultative anaerobes. streptococci Carrine Blank A multicellular relationship of prokaryotic cells where the shape of the cells is round (forming a coccus) and the cells are attached to one another end-to-end to form chains. staphylococcus A multicellular relationship of prokaryotic cells where the shape of the cells is round (forming a coccus) and the cells are attached to one another end-to-end and side-to-side to form clumps or clusters. staphylococci Wikipedia:Staphylococcus Staphylococcus (from the Greek: σταφυλή, staphylē, "grape" and κόκκος, kókkos, "granule") is a genus of Gram-positive bacteria. Under the microscope, they appear round (cocci), and form in grape-like clusters.
