Gram-negative
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane. Gram-negative bacteria are found in virtually all environments on Earth that support life. The gram-negative bacteria include the model organism ''Escherichia coli'', as well as many pathogenic bacteria, such as ''Pseudomonas aeruginosa'', ''Chlamydia trachomatis'', and ''Yersinia pestis''. They are a significant medical challenge as their outer membrane protects them from many antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and lysozyme, an antimicrobial enzyme produced by animals that forms part of the innate immune system. Additionally, the outer leaflet of this membrane comprises a complex lipo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacterium
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 relationshi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sterilization (microbiology)
Sterilization refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents such as prions present in or on a specific surface, object, or fluid. Sterilization can be achieved through various means, including heat, chemicals, irradiation, high pressure, and filtration. Sterilization is distinct from disinfection, sanitization, and pasteurization, in that those methods reduce rather than eliminate all forms of life and biological agents present. After sterilization, an object is referred to as being sterile or aseptic. Applications Foods One of the first steps toward modernized sterilization was made by Nicolas Appert, who discovered that application of heat over a suitable period slowed the decay of foods and various liquids, preserving them for safe consumption for a longer time than was typical. Canning of foods is an extension of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oberpfalz
The Upper Palatinate (german: Oberpfalz, , ) is one of the seven administrative districts of Bavaria, Germany, and is located in the east of Bavaria. Geography The Upper Palatinate is a landscape with low mountains and numerous ponds and lakes in its lowland regions. By contrast with other regions of Germany it is more rural in character and more sparsely settled. It borders (clockwise from the north) on Upper Franconia, the Czech Republic, Lower Bavaria, Upper Bavaria and Middle Franconia. Notable regions are: * Stiftland, former estate and territorial lordship of Waldsassen Abbey with the market town of Konnersreuth, Fockenfeld Abbey, the town of Waldsassen and about 150 other villages. * Upper Palatine Forest with deep valleys and many castles * Upper Palatine Lake District with the Steinberger See * Upper Palatine Jura, part of the Franconian Jura * Steinwald including the Teichelberg and Pechbrunn * Waldnaab/ Wondreb Depression * Bavarian Forest, together with the Boh ...

Burkholderiales
The Burkholderiales are an order of Pseudomonadota.George M. Garrity: '' Bergey's Manual of Systematic Bacteriology''. 2. Auflage. Springer, New York, 2005, Vol. 2: ''The Proteobacteria Part C: The Alpha-, Beta-, Delta-, and Epsilonproteabacteria'' Like all Pseudomonadota, they are Gram-negative. They include several pathogenic bacteria, including species of ''Burkholderia'', ''Bordetella'', and ''Ralstonia''. They also include '' Oxalobacter'' and related genera, which are unusual in using oxalic acid as their source of carbon. Other well-studied genera include ''Alcaligenes'', '' Cupriavidus'', ''Achromobacter'', ''Comamonas'', '' Delftia'', ''Massilia'', '' Duganella'', '' Janthinobacterium'', ''Polynucleobacter'' (important freshwater bacterioplankton), non-pathogenic ''Paraburkholderia'', '' Caballeronia'', '' Polaromonas'', ''Thiomonas'', ''Collimonas'', '' Hydrogenophaga'', ''Sphaerotilus'', '' Variovorax'', '' Acidovorax'', '' Rubrivivax'' and ''Rhodoferax'' (both members ...
