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. The Gram stain is used by microbiologists to place bacteria into two main categories, gram-positive (+) and gram-negative bacteria, gram-negative (−). Gram-positive bacteria have a thick layer of peptidoglycan within the cell wall, and gram-negative bacteria have a thin layer of peptidoglycan. Gram-positive bacteria retain the crystal violet stain used in the test, resulting in a purple color when observed through an optical microscope. The thick layer of peptidoglycan in the bacterial cell wall retains the Stain (biology), stain after it has been fixed in place by iodine. During the decolorization step, the decolorizer removes crystal violet from all other cells. Conversely, gram-negative bacteria cannot retain the violet stain after the decolorization ...

Rod-shaped
Bacterial cellular morphologies are the shapes that are characteristic of various types of bacteria and often key to their identification. Their direct examination under a light microscope enables the classification of these bacteria (and archaea). Generally, the basic morphologies are spheres (coccus) and round-ended cylinders or rod shaped (bacillus). But, there are also other morphologies such as helically twisted cylinders (example '' Spirochetes''), cylinders curved in one plane (selenomonads) and unusual morphologies (the square, flat box-shaped cells of the Archaean genus '' Haloquadratum)''. Other arrangements include pairs, tetrads, clusters, chains and palisades. Types Coccus A coccus (plural ''cocci'', from the Latin ''coccinus'' (scarlet) and derived from the Greek ''kokkos'' (berry)), is any microorganism (usually bacteria) whose overall shape is spherical or nearly spherical. Coccus refers to the shape of the bacteria and can contain multiple genera, such as s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lysinibacillus
''Lysinibacillus'' is a genus of bacteria from the family of Bacillaceae. Members of this genus, in contrast to the type species of the genus ''Bacillus'', contains peptidoglycan with lysine, aspartic acid, alanine and glutamic acid. Phylogeny The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI) ''Lysinibacillus'' species assigned to other genera: * ''Lysinibacillus alkaliphilus, L. alkaliphilus'' Zhao et al. 2015 * ''Lysinibacillus alkalisoli, L. alkalisoli'' Sun, Xu & Wu 2017 * ''Lysinibacillus antri, L. antri'' Narsing Rao et al. 2020 * ''Lysinibacillus composti, L. composti'' Hayat et al. 2014 * ''Lysinibacillus endophyticus, L. endophyticus'' Yu et al. 2017 * ''Lysinibacillus halotolerans, L. halotolerans'' Kong et al. 2014 * ''Lysinibacillus louembei, L. louembei'' Ouoba et al. 2015 * ''Lysinibacillus meyeri, L. meyeri'' Seiler, Scherer & Wenning 2013 * ''L. ...

Karst Cave
Karst () is a topography formed from the dissolution of soluble carbonate rocks such as limestone and dolomite. It is characterized by features like poljes above and drainage systems with sinkholes and caves underground. There is some evidence that karst may occur in more weathering-resistant rocks such as quartzite given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. In regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Libo County
Libo County () is a county of southern Guizhou province, China, bordering Guangxi to the south. It is under the administration of the Qiannan Buyei and Miao Autonomous Prefecture. Geography The county is located in the remote southeastern corner of the prefecture, on the border with Guangxi. Two local sites, Xiaoqikong () and Dongduo (), notable for their spectacular karst formations, form part of the multi-site South China Karst UNESCO World Heritage Site inscribed in 2007, which is an area about 550,000 km2 in extent. Administrative divisions Libo County is divided into 1 Subdistricts of China, subdistrict, 5 Towns of China, towns and 2 Ethnic townships, towns, and sums, ethnic township: ;subdistrict *Yuping Subdistrict 玉屏街道 ;towns *Chaoyang Town 朝阳镇 *Maolan Town 茂兰镇 *Jialiang Town 甲良镇 *Jiarong Town 佳荣镇 *Xiaoqikong Town 小七孔镇 ;ethnic townships *Yaoshan Yao Ethnic Township 瑶山瑶族乡 *Limingguan Shui Ethnic Township 黎明关水族乡 ...

Bacillaceae
Bacillaceae, from Latin "bacillus", meaning "little staff, wand", are a family of gram-positive, heterotrophic, rod-shaped bacteria that may produce endospores. Motile members of this family are characterized by peritrichous flagella. Some Bacillaceae are aerobic, while others are facultative or strict anaerobes. Most are not pathogenic, but ''Bacillus'' species are known to cause disease in humans. Gram-variable cell wall Some Bacillaceae, such as the genera '' Filobacillus, Lentibacillus,'' and '' Halobacillus'', stain Gram-negative or Gram-variable, but are known to have a Gram-positive cell wall.Lim, J.M., Jeon, C.O., Song, S.M., and C.J.
