LPSN
List of Prokaryotic names with Standing in Nomenclature (LPSN) is an online database that maintains information on the naming and taxonomy of prokaryotes, following the taxonomy requirements and rulings of the International Code of Nomenclature of Prokaryotes. The database was curated from 1997 to June 2013 by Jean P. Euzéby. From July 2013 to January 2020, LPSN was curated by Aidan C. Parte. In February 2020, a new version of LPSN was published as a service of the Leibniz Institute DSMZ, thereby also integrating the Prokaryotic Nomenclature Up-to-date service.

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 ...

Amphitheatre Of El Jem
The Amphitheatre of El Jem is an oval amphitheatre in the modern-day city of El Djem, Tunisia, formerly Thysdrus in the Roman province of Africa. It is listed by UNESCO since 1979 as a World Heritage Site. History The amphitheatre was built around 238 AD in Thysdrus, located in the Roman province of Africa Proconsularis in present-day El Djem, Tunisia. It is one of the best preserved Roman stone ruins in the world, and is unique in Africa. As other amphitheatres in the Roman Empire, it was built for spectator events, and it is one of the biggest amphitheatres in the world. The estimated capacity is 35,000, and the sizes of the big and the small axes are respectively and . The amphitheatre is built of stone blocks, located on a flat ground, and is exceptionally well conserved. The amphitheatre of El Jem is the third amphitheatre built on the same place. The belief is that it was constructed by the local proconsul Gordian, who became emperor as Gordian III. In the Middle Ages, it ...

El Jem
El Djem or El Jem (Tunisian Arabic:, ') is a town in Mahdia Governorate, Tunisia. Its population was 21,576 during the 2014 census. It is home to Roman remains including the " Amphitheater of El Jem". History The Roman city of Thysdrus was built, like almost all Roman settlements in ancient Tunisia, on former Punic settlements. In a less arid climate than today's, Thysdrus prospered as an important center of olive oil production and export. It was the seat of a Christian bishopric, which is included in the Catholic Church's list of titular sees. By the early 3rd century, when the amphitheater was built, Thysdrus rivaled Hadrumetum (modern Sousse) as the second city of Roman North Africa after Carthage. However, following the abortive revolt that began there in AD238 and Gordian's suicide in his villa near Carthage, Roman troops loyal to the emperor Maximinus Thrax sacked the city. The town is shown on the 4th-century Peutinger Map. Sights Amphitheater The Amphitheatre of El ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bacteria Described In 2017
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 relationships w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
