Alicyclobacillus Sacchari
''Alicyclobacillus sacchari'' is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produce endospores. It was first isolated from liquid sugar. The species was first described in 2007, and the name is derived from the Latin ''sacchari'' (of sugar). The optimum growth temperature for ''A. sacchari'' is 45-50 °C, and can grow in the 30-55 °C range. The optimum pH is 4.0-4.5, and cannot grow at pH 2.0 or pH 6.0. ''A. sacchari'' was found during a Japanese survey of various beverages and environments, which also discovered 5 other species of ''Alicyclobacillus'': ''Alicyclobacillus contaminans, A. contaminans'', ''Alicyclobacillus fastidiosus, A. fastidiosus'', ''Alicyclobacillus kakegawensis, A. kakegawensis'', ''Alicyclobacillus macrosporangiidus, A. macrosporangiidus'', ''Alicyclobacillus contaminans, A. contaminans'', and ''Alicyclobacillus shizuokensis, A. shizuokensis''.

Bacteria
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 relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacillota
The Bacillota (synonym Firmicutes) are a phylum of bacteria, most of which have gram-positive cell wall structure. The renaming of phyla such as Firmicutes in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature. The name "Firmicutes" was derived from the Latin words for "tough skin," referring to the thick cell wall typical of bacteria in this phylum. Scientists once classified the Firmicutes to include all gram-positive bacteria, but have recently defined them to be of a core group of related forms called the low- G+C group, in contrast to the Actinomycetota. They have round cells, called cocci (singular coccus), or rod-like forms (bacillus). A few Firmicutes, such as ''Megasphaera'', ''Pectinatus'', ''Selenomonas'' and ''Zymophilus'', have a porous pseudo-outer membrane that causes them to stain gram-negative. Many Bacillota (Firmicutes) produce endospores, which are resistant to desiccation and can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacilli
Bacilli is a taxonomic class of bacteria that includes two orders, Bacillales and Lactobacillales, which contain several well-known pathogens such as ''Bacillus anthracis'' (the cause of anthrax). ''Bacilli'' are almost exclusively gram-positive bacteria. The name ''Bacillus'', capitalized and italicized, refers to a specific genus of bacteria. The name Bacilli, capitalized but not italicized, can also refer to a less specific taxonomic group of bacteria that includes two orders, one of which contains the genus ''Bacillus''. When the word is formatted with lowercase and not italicized, 'bacillus', it will most likely be referring to shape and not to the genus at all. Ambiguity Several related concepts make use of similar words, and the ambiguity can create considerable confusion. The term "''Bacillus''" (capitalized and italicized) is also the name of a genus (''Bacillus anthracis'') that, among many other genera, falls within the class Bacilli.

Alicyclobacillaceae
The Alicyclobacillaceae are a family of Gram-positive bacteria. All members of this family are aerobic and form endospores. The family contains four genera: ''Alicyclobacillus'', ''Effusibacillus'', '' Kyrpidia'', and '' Tumebacillus''. When originally created in 2009, Alicyclobacillaceae was a monophyletic family, only including genus ''Alicyclobacillus''. In 2011, the novel genus '' Kyrpidia'' was proposed and placed in family Alicyclobacillaceae, and '' Tumebacillus'' was placed into the family as well. In 2014, the novel genus ''Effusibacillus'' was proposed and added as the fourth member of Alicyclobacillaceae. ''Alicyclobacillus'' is the largest genus in Alicyclobacillaceae, with over 20 validly published species. The species are all acidophilic and have thermally resistant endospores. Many species are common soil organisms. Certain ''Alicyclobacillus'' species (especially '' A. acidoterrestris'') have been implicated in spoilage of pasteurized fruit juice. ''Effusibacill ...

Alicyclobacillus
''Alicyclobacillus'' is a genus of Gram-variable, rod-shaped, spore-forming bacteria. The bacteria are able to grow in acidic conditions, while the spores are able to survive typical pasteurization procedures. Overview ''Alicyclobacilli'' are strictly aerobic, acidophilic, mesophilic to thermophilic, soil-dwelling organisms. ''Alicyclobacilli'' are of special interest to the fruit juice canning industry because common pasteurization techniques (92 °C for 10 seconds) do not deactivate the spores; ''Alicyclobacillus'' species can have a D95-value of over 8 minutes (requiring treatment of over 8 minutes at 95 °C to kill 90% of spores). When a product is spoiled by ''Alicyclobacillus'', the juice products develop a disinfectant-like odor and/or flavor (due to guaiacol production), but the bacteria do not cause swelling of the package or discoloration of the product, nor is it pathogenic to humans. ''Alicyclobacilli'' have been implicated in spoilages of pear, orange, pea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (s ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

It was first isolated from apple juice. The species was first described in 2007, and the name refers to the fastidious nature of the organism; the bacteria would start to die off after 7 days when plated on typical agar for isolating ''Alicyclobacillus''. Additionally, the species produced fewer spores than other members of its genus, and took much longer to produce the spores (i.e. several days versus 10 days). The optimum growth temperature for ''A. fastidiosus'' is 40–45 °C, and can grow in the 20–55 °C range. The optimum pH is 4.0–4.5, and cannot grow at pH 2.0 or p ...
