Anaerosolibacter

Anaerosolibacter is a genus of bacteria in the family Clostridiaceae. The genus contains biotechnologically important species that are capable of producing biohydrogen and other valuable chemicals. The name "Anaerosolibacter" is derived from the Greek words "an" (without), "aeros" (air), "solibos" (soil), and "bacter" (rod), indicating that these bacteria are anaerobic, soil-dwelling rods.

Characteristics

Anaerosolibacter species are Gram-positive, rod-shaped, and anaerobic. They are spore-forming bacteria, which allows them to survive in harsh environmental conditions. The bacteria are also chemoorganotrophic, meaning they obtain energy by oxidizing organic compounds.

Metabolism

Anaerosolibacter species are capable of fermenting a variety of organic substrates, including glucose, xylose, and arabinose. The end products of fermentation are typically hydrogen, carbon dioxide, and acetate. Some species can also produce butyrate and lactate.

Biotechnological Applications

Due to their ability to produce biohydrogen, Anaerosolibacter species have potential applications in bioenergy production. They can also be used in the production of other valuable chemicals, such as butanol, acetone, and ethanol.

Species

The genus Anaerosolibacter currently includes two recognized species:

• Anaerosolibacter massiliensis
• Anaerosolibacter bizertensis

Both species were isolated from human fecal samples and have been found to be non-pathogenic.
