    Thermophilic eubacteria are suggested to have been among the earliest bacteria. [3] Thermophiles are found in various geothermally heated regions of the Earth , such as hot springs like those in Yellowstone National Park (see image) and deep sea hydrothermal vents , as well as decaying plant matter, such as peat bogs and compost. Acidophiles are ecologically and economically important group of microorganisms, which thrive in acidic natural (solfataric fields, sulfuric pools) as well as artificial man-made (areas associated with human activities such as mining of coal and metal ores) environments. They possess networked cellular adaptations to regulate pH inside the cell.

    Detection and isolation of thermophilic acidophilic bacteria from fuit juices Duvenage, Wineen ( 2006-03 ) Thesis (Msc Food Sc (Food Science))--University of Stellenbosch, 2006. The main thermophilic bacteria used in the production of fermented milks include lactobacilli, Streptococcus thermophilus and bifidobacteria. DNA fingerprinting is now commonly used to determine the taxonomic location of these organisms. As a result, important changes have been made to the taxonomic status of certain well-known starter bacteria.

    Thermoacidophile - Wikipedia

    A thermoacidophile is an extremophilic microorganism that is both thermophilic and acidophilic; i.e., it can grow under conditions of high temperature and low pH. The large majority of thermoacidophiles are archaea (particularly the crenarchaeota and euryarchaeota) or bacteria, though occasional eukaryotic examples have been reported. Acidophiles or acidophilic organisms are those that thrive under highly acidic conditions (usually at pH 2.0 or below). These organisms can be found in different branches of the tree of life , including Archaea , Bacteria , [1] and Eukarya . Some moderately thermophilic acidophilic bacteria such as Bacillus fumarioli are included in the abbreviation, TAB, in a broader sense. Other abbreviations commonly used internationally are AAT ...

    Alicyclobacillus - Wikipedia

    The first Alicyclobacillus species was isolated in 1967 from hot springs, and was named Bacillus acidocaldarius. However, it was not until 1982 that the organisms were implicated in the spoilage of apple juice. The next outbreak occurred in 1994, and based on 16S rRNA studies, a separate genus was proposed. Based on 16S rRNA sequencing, many moderately thermophilic, iron-oxidizing bacteria appear to be phylogenetically clustered among or near gram-positive microorganisms (20, 24).However, the traditional Gram-staining technique frequently gives variable or unrecognizable results for gram-positive mining bacteria (data not shown).

    Extremely thermophilic microorganisms 289 genera Sulfolobus, Metallosphaera, Acidianus, and Desulfurolobus (47). On the other hand, the slightly acidophilic and neutrophilic thermophiles are found both in continental solfataric fields and in submarine hydrothermal systems. All of them are strict anaerobes. Solfataric fields contain members of the the product. In this respect, thermophilic acidophilic bacilli are difficult bacteria to understand. Spoilage caused by these bacteria occurs not only in Japan but all over the world. They are troublesome bacteria not only for consumers but also for soft drink producers from an ingredient-sourcing and sanitation point of view.

    On the acidostability of an acidophilic thermophilic bacterium

    When an acidophilic thermophilic bacterium, Bacillus sp., is exposed to acid environment (pH 4.0) without glucose, the cell suspension consumes H +.When the cells respire glucose, no consumption of H + by the cell suspension is observed. On addition of respiratory inhibitor or uncoupler to the cell suspension containing glucose, however, the suspension consumes H +. A novel, moderately thermophilic, acidophilic, Gram-variable, rod-shaped, endospore-forming bacterium was isolated from a spoiled mixed vegetable and fruit juice product that had the off-flavour of guaiacol. The bacterium, strain 4FT, grew aerobically at 20–50 °C (optimum 40 °C) and pH 3.0–6.0 (optimum pH 4.0) and produced acid from glycerol, d-galactose and d-glucose. A group of Alicyclobacillus strains, responsible for the tainting of fruit juices, was then described as A. a- doterrestris in 1999. They are acidophilic and grow preferably at around pH 4. 0. They are thermophilic and grow better at temperatures above 40 °C. This indicates that we might have been missing them by our or- nary methods of ...

    Thermophilic Bacteria - an overview | ScienceDirect Topics

    Among obligately anaerobic thermophilic bacteria, advances relevant to gene transfer methods over the last 10 years have been reported for three Gram-positive species that ferment carbohydrates to ethanol, acetate, lactate, H 2 and CO 2: Clostridium thermocellum, Thermoanaerobacterium saccharolyticum strain JW/SL-YS485 and Thermoanaerobacterium thermosaccharolyticum. Individual bacteria may be rod or sphere shaped, but they often join end to end to form long strands called filaments. These strands help bind thermophilic mats, forming a vast community or miniecosystem. Other groups of bacteria form layered structures resembling tiny towers, which can trap sand and other organic materials.

    Acidophiles or acidophilic : here they are placed alive beings that manage to survive in sites of great acidity, being an example in this respect the organisms of eukaryotic type. They are rare, although used in various industries as they manage to eliminate other bacteria and prevent their spread. The growth and oxygen consumption of a variety of thermophilic, acidophilic bacteria in the presence of thiophene-2-carboxylate (T2C) and dibenzothiophene (DBT) have been determined.

    SUMMARY: A series of extremely thermophilic acidophilic bacteria has been characterized as closely resembling the species Sulfolobus acidocaldarius except for a totally different guanosine-cytosine content in the DNA; some conceptual consequences of this situation are discussed. Both organisms also share special features, including a very characteristic type of ether lipid, with other extreme ... Two isolates of a novel, moderately thermophilic Thiobacillus species have been studied. The isolates, KU and BC13, are Gram-negative, motile bacteria having a pH optimum for growth of 2-2.5 and an optimum growth temperature of 45 °C. Both isolates are capable of chemolithotrophic growth on reduced sulfur substrates. They can also use molecular hydrogen as an electron donor.
