Description and Significance
A. acidoterrestris is an aerobic, gram positive, thermoacidophilic bacilli that produces endospores. It can survive in acidic environments down to 2.5 pH and grows at temperatures between 26°C and 55°C. The significance of this bacteria lies in its ability to contaminate juice products and survive the pasteurization process used to remove bacteria due to the heartiness of its endospores. This bacteria is found growing in soils, fruit juices, and orchards.
Genome Structure
The genome is 4,063,548 base pairs, singular, and circular. It has a Guanine -Cytosine content of 52.2% and contains about 4,145 protein coding genes. The genome contains a sporulation transcription activator that shares a 61% similarity with the Spo0A found in Bacillus subtilis and sporulation Kinase A (KinA) was also preserved in this genome.
- Fw Sequence: 5’-AGAGTTTGATCCTGGCTCA-3’, positions 8 to 26
- Rw Sequence: 5’-CGGCTACCTTGTTACGGAC-3’, positions 1511 to 1493
Cell Structure, Metabolism and Life Cycle
A. acidoterrestris falls into the class bacillus, making it rod shaped. It is a prokaryotic cell lacking membrane bound organelles. Its life cycle consists of three processes, vegetative growth, sporulation, then germination. It is strictly aerobic, acidophilic, and thermophilic. A. acidoterrestris survives by metabolizing vitamin K, methylglyoxal, adipate, and propanol. It produces bromophenol and guaiacol, which are responsible for a spoiled taste in juice that A. acidoterrestris colonizes.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment. If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
