Brachybacterium Fresconis
''Brachybacterium fresconis'' is a species of Gram positive, strictly aerobic, cream-pigmented bacterium. The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. It was first isolated from a medieval wall painting of the chapel of Schloss Herberstein in Styria, Austria. The species was proposed in 2014, and the name is derived from the fact it was first isolated from a fresco Fresco ( or frescoes) is a technique of mural painting executed upon freshly laid ("wet") lime plaster. Water is used as the vehicle for the dry-powder pigment to merge with the plaster, and with the setting of the plaster, the painting become .... The optimum growth temperature for ''B. fresconis'' is 20-30 °C, but can grow in the 5-40 °C range.

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 (−). 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 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 step; alcohol used in this stage deg ...

Aerobics
Aerobics is a form of physical exercise that combines rhythmic aerobic exercise with stretching and strength training routines with the goal of improving all elements of fitness (Flexibility (anatomy), flexibility, Muscle, muscular strength, and Circulatory system, cardio-vascular fitness). It is usually performed to music and may be practiced in a group setting led by an Teacher, instructor (fitness professional). With the goal of preventing illness and promoting physical fitness, practitioners perform various routines. Formal aerobics classes are divided into different levels of intensity and complexity and will have five components: warm-up (5–10 minutes), cardiovascular conditioning (25–30 minutes), muscular strength and conditioning (10–15 minutes), cool-down (5–8 minutes) and stretching and flexibility (5–8 minutes). Aerobics classes may allow participants to select their level of participation according to their fitness level. Many gyms offer different types of aer ...

Bacterium
Bacteria (; : 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 the air, soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and 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 mutualistic, commensal and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medieval
In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to the late 15th centuries, similarly to the post-classical period of World history (field), global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early Middle Ages, Early, High Middle Ages, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralised authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the ...

Schloss Herberstein
Schloss Herberstein is a castle in Styria, Austria. Schloss Herberstein is situated at an elevation of . Castle and the surrounding area Herberstein Castle sits on a rock in the ravine and thus is not accessible from 3 sides. At the same time, the castle is not visible from out of the ravine and was thus naturally protected from attackers. The oldest parts of the caste situated near the zoo stems from the 12th century. The first small castle called 'Herwigstein' (named after Herwig of Krottendorf) stood under the fiefdom of the Stubenberg Clan. Otto von Hartenberg could free the castle by a payment to the Stubenbergs and is considered to be the ancestor of Herberstein Castle since then. By 1400 the castle was expanded by a massive outer bailey, which included the previously built Gothic chapel of St. Catherine. The bailey was extended in the 15th century a number times. Mid-16th century, the castle was transformed into a residential building with Renaissance elements and expand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Styria
Styria ( ; ; ; ) is an Austrian Federal states of Austria, state in the southeast of the country. With an area of approximately , Styria is Austria's second largest state, after Lower Austria. It is bordered to the south by Slovenia, and clockwise, from the southwest, by the other Austrian states of Carinthia, Salzburg (federal state), Salzburg, Upper Austria, Lower Austria, and Burgenland. The state's capital is Graz, the second largest city in Austria after only Vienna. Name The March of Styria derived its name from the original seat of its ruling Otakars, Otakar dynasty: Steyr, in today's Upper Austria, which in turn derives its name from the namesake river of Steyr, stemming from the Celtic Stiria. In the native German the area is still called "Steiermark", while in English the Latin name "Styria" is used. Until the late 19th century however, the German name "Steyer", a slightly modernized spelling of Steyr, was also common. The ancient link between the city of Steyr and S ...

Austria
Austria, formally the Republic of Austria, is a landlocked country in Central Europe, lying in the Eastern Alps. It is a federation of nine Federal states of Austria, states, of which the capital Vienna is the List of largest cities in Austria, most populous city and state. Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has Austrians, a population of around 9 million. The area of today's Austria has been inhabited since at least the Paleolithic, Paleolithic period. Around 400 BC, it was inhabited by the Celts and then annexed by the Roman Empire, Romans in the late 1st century BC. Christianization in the region began in the 4th and 5th centuries, during the late Western Roman Empire, Roman period, followed by the arrival of numerous Germanic tribes during the Migration Period.

Fresco
Fresco ( or frescoes) is a technique of mural painting executed upon freshly laid ("wet") lime plaster. Water is used as the vehicle for the dry-powder pigment to merge with the plaster, and with the setting of the plaster, the painting becomes an integral part of the wall. The word ''fresco'' () is derived from the Italian adjective ''fresco'' meaning "fresh", and may thus be contrasted with fresco-secco or secco mural painting techniques, which are applied to dried plaster, to supplement painting in fresco. The fresco technique has been employed since antiquity and is closely associated with Italian Renaissance painting. The word ''fresco'' is commonly and inaccurately used in English to refer to any wall painting regardless of the plaster technology or binding medium. This, in part, contributes to a misconception that the most geographically and temporally common wall painting technology was the painting into wet lime plaster. Even in apparently '' buon fresco'' technology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
