What is thermophilic acidophilic bacteria?
What is thermophilic acidophilic bacteria?
Alicyclobacillus spp., also known as Thermophilic Acidophilic Bacteria (TAB), are spoilage organisms in the fruit juice industry. They can generate strong off flavors and off odors due to guaiacol or bromophenols production. Contamination with these non-pathogenic bacteria can occur at various stages of the process.
Where is alicyclobacillus Acidoterrestris found?
tropical juices
It is most likely to be found in tropical juices. Alicyclobacillus acidoterrestris. This bacteria is a thermophile and the spores are extremely resistant to heat.
Is Alicyclobacillus an acidophile?
Alicyclobacillus spp., are Gram-positive, non-pathogenic, thermophilic and acidophilic spore-forming bacteria found in acid hot springs and in soil.
What are alicyclobacillus sp?
Alicyclobacillus is a genus of rod-shaped, Gram-positive bacteria that is usually recovered from soil, orchards, acidic drinks, and equipment from fruit juice manufacturers.
What purpose does alicyclobacillus Acidoterrestris serve?
Because A. acidoterrestris spores survive high temperatures and acidic environments, they often serve as targets for the design of thermal processes for fruit juices (Chang and Kang 2004).
What is juice Spore?
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.
Where does alicyclobacillus Acidocaldarius live?
A strain of A. acidocaldarius has been isolated from thermally heated soils of Mount Rittmann in Antarctica. A. acidocaldarius was among the first three species reclassified from the genus Bacillus to the newly created Alicyclobacillus in 1992, along with A.
Can bacteria live in acid?
Most bacteria grow best around neutral pH values (6.5 – 7.0), but some thrive in very acid conditions and some can even tolerate a pH as low as 1.0. Such acid loving microbes are called acidophiles. Even though they can live in very acid environments, their internal pH is much closer to neutral values.

Which is the correct term for Alicyclobacillus bacilli?
Alicyclobacillus: Thermophilic acidophilic Bacilli. TAB, the abbreviation for Thermo Acidophillic Bacilli (or Bacteria) is the most widely utilized way to designate the bacteria belonging to genus Alicyclobacillus, and while it is not an exact label for Alicyclobacillus, it has come to be accepted as synonym.
What kind of temperature does Alicyclobacillus grow best?
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.

Is the Alicyclobacillus bacteria harmful to humans?
Fortunately, Alicyclobacillus are not pathogenic bacteria, but they are troublesome, not only for consumers but also for beverage producers, because no effective control methods have yet been developed.
