Bartolomeo Bizio
Bartolomeo Bizio (30 October 1791 - 27 September 1862) was an Italian chemist and a pioneer of microbiology who examined bloody spots on polenta and recognized them as being caused by a microorganism that he named as ''Serratia'' after the Florentine physicist Serafino Serrati. Bizio was the son of tailor Giovanni Bizio and Paolina née Zampieroni born in Costozza di Longare, Venice who grew up in Padua working as a tailor. He was educated in Padua and around 1809 he worked at the Zanichelli pharmacy. He suffered from eye strain and later became a physics teacher after meeting Abbot Cicuto. He then trained at the University to become a pharmacist in 1820. Around 1819 he examined the phenomenon of "bloody polenta", initially claimed to be a miracle, and examined the cause of the red spots on corn meal and other starchy foods. He identified the cause as being an organism. He identified that the seeds of the microscopic organism were present in the air by showing that spots appeared ...

Serratia
''Serratia'' is a genus of Gram-negative, facultatively anaerobic, rod-shaped bacteria of the family Yersiniaceae. According to the List of Prokaryotic names with Standing Nomenclature (LPSN), there are currently 19 species of ''Serratia'' that are credibly published with accurate names as of 2020: ''S. aquatilis, S. entomophila, S. ficaria, S. fonticola, S. grimesii, S. liquefaciens, S. marcescens, S. microhaemolytica, S. myotis, S. nematodiphila, S. odoriferae, S. oryzae, S. plymuthica, S. proteamaculans, S. quinivorans corrig, S. rubidaea, S. symbiotica, S. ureilytica, S. vespertilionis''. They are typically 1–5 μm in length, do not produce spores, and can be found in water, soil, plants, and animals. Some members of this genus produce a characteristic red pigment, prodigiosin, and can be distinguished from other members of the order Enterobacterales by their unique production of three enzymes: DNase ( nucA), lipase, and gelatinase ( serralysin). ''Serratia'' was thought t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serafino Serrati
Serafino Serrati (18th-century) was an Italians, Italian Benedictine order, Benedictine monk, who also practiced or taught physical sciences. He appears to have lived in the Badia Fiorentina (Florentine Abbey of monks of the order of Monte Cassino). He is now best remembered because the bacterial genus for a specific gram-negative rod-shaped bacteria called Serratia is named after him in 1819 by the botanist and chemist Bartolomeo Bizio (1791 – 1862) to honor him for his unrecognized invention of a steamboat. Biography Information regarding Serafino is limited. Born in the 18th-century in Florence to a respectable family, he appears to have studied physics and botany. He is thought to have been the professor of experimental physics in his monastery. Among his preferred studies was to find ways to direct the movement of ''globi areostatici'', today in English referred to as hot-air balloons. It is said that his fellow monk Rabatta and Serrati were the first Florentines to become ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Padua
Padua ( ; it, Padova ; vec, Pàdova) is a city and ''comune'' in Veneto, northern Italy. Padua is on the river Bacchiglione, west of Venice. It is the capital of the province of Padua. It is also the economic and communications hub of the area. Padua's population is 214,000 (). The city is sometimes included, with Venice (Italian ''Venezia'') and Treviso, in the Padua-Treviso-Venice Metropolitan Area (PATREVE) which has a population of around 2,600,000. Padua stands on the Bacchiglione River, west of Venice and southeast of Vicenza. The Brenta River, which once ran through the city, still touches the northern districts. Its agricultural setting is the Venetian Plain (''Pianura Veneta''). To the city's south west lies the Euganaean Hills, praised by Lucan and Martial, Petrarch, Ugo Foscolo, and Shelley. Padua appears twice in the UNESCO World Heritage List: for its Botanical Garden, the most ancient of the world, and the 14th-century Frescoes, situated in dif ...

Polenta
Polenta (, ) is a dish of boiled cornmeal that was historically made from other grains. The dish comes from Italy. It may be served as a hot porridge, or it may be allowed to cool and solidify into a loaf that can be baked, fried, or grilled. The variety of cereal used is usually yellow maize, but often buckwheat, white maize, or mixtures thereof may be used. Coarse grinds make a firm, coarse polenta; finer grinds make a soft, creamy polenta. Polenta is a staple of Northern Italian, Swiss and Balkan (where it is called kačamak or žganci) cuisines (and, to a lesser extent, the Central Italian one, e.g. Tuscany) and its consumption was traditionally associated with lower classes, as in times past cornmeal mush was an essential food in their everyday nutrition. Etymology covered any hulled and crushed grain, especially barley-meal, and is derived from the for 'fine flour,' which shares a root with , meaning 'dust.'''Oxford English Dictionary'' 3rd edition, 2006''s.v.''/re ...

Angelo Bellani
Angelo Bellani (1776 - 1852) was an Italian priest who also took an interest in physics and is best known for his work in the measurement of temperature and humidity using instruments and his inventions included a temperature recording thermograph. He started a company for producing standardized thermometers. Bellani was born in Monza where he trained to become a priest. He also took an interest in physics and was involved in debates with Alessandro Volta on the origin of hail. He also argued against the ideas of Paolo Beltrami. Bellani noted that thermometers had problems with the stability of their zero point (0°C as marked by placing in ice) due to defects in their construction and the quality of glass used. He also used a U shaped glass that inspired James Six to produce the minimum-maximum thermometer. In 1820 Bellani invented a device for measuring evaporation that was called an atmometer. Modified versions of the Bellani plate evaporimeter are still in use. He invented a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Murex Trunculus
''Hexaplex trunculus'' (previously known as ''Murex trunculus'', ''Phyllonotus trunculus'', or the banded dye-murex) is a medium-sized sea snail, a marine gastropod mollusk in the family Muricidae, the murex shells or rock snails. It is included in the subgenus ''Trunculariopsis''. This species is a group of opportunist predatory snails that are known to attack their prey in groups. What is peculiar about this specific species is that they show no preference for the size of their prey, regardless of their hunger levels. The snail appears in fossil records dating between the Pliocene and Quaternary periods (between 3.6 and 0.012 million years ago). Fossilized shells have been found in Morocco, Italy, and Spain. This sea snail is historically important because its hypobranchial gland secretes a mucus used to create a distinctive purple-blue indigo dye. Ancient Mediterranean cultures, including the Minoans, Canaanites/Phoenicians, Hebrews, and classical Greeks created dyes from t ...

Murex Brandaris
''Bolinus brandaris'' (originally called ''Murex brandaris'' by Linnaeus and also Haustellum brandaris), and commonly known as the purple dye murex or the spiny dye-murex, is a species of medium-sized predatory sea snail, an edible marine gastropod mollusk in the family Muricidae, the murex snails or the rock snails. This species is known in the fossil record from the Pliocene (age range: from 3.6 to 2.588 million years ago). Fossil shells of this species have been found in Cyprus, Spain and Italy. It was used by the Phoenicians in ancient times to extract imperial Tyrian purple dye. Distribution and habitat This snail lives in the central and western parts of the Mediterranean Sea and has been found on isolated coral atoll beaches in the Indian Ocean and South China Sea. It was known since ancient times as a source for purple dye and also as a popular food source under various names, among which ''sconciglio'', from which comes the word ''scungilli''. This species lives on rocks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Year 186 ( CLXXXVI) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Glabrio (or, less frequently, year 939 '' Ab urbe condita''). The denomination 186 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
