Characteristics of Exiguobacterium aurantiacum
- Exiguobacterium aurantiacum is a species of bacteria that belongs to the genus Exiguobacterium, which accommodates many versatile species isolated from diverse environments 1.
- This species is known to be alkaliphilic, halotolerant, and non-spore-forming Gram-positive bacilli 2.
- Exiguobacterium aurantiacum can form orange-yellow pigmented colonies on blood agar and is catalase- and DNase-positive 2.
Habitat and Isolation
- Exiguobacterium aurantiacum has been isolated from various environmental samples, including saline ponds 3 and distilled water 4.
- This species has also been isolated from patients with bacteremia, particularly those with myeloma 4, 2.
- Exiguobacterium aurantiacum can be found in extreme environmental conditions, such as high heavy metal and salt concentrations and high alkalinity 3.
Biotechnological Potential
- Exiguobacterium aurantiacum has been explored for its potential in bioremediation and degradation of toxic substances released into the environment 1, 5.
- This species has also been found to have the ability to synthesize nanostructures containing silver, gold, or tellurium, which could have biotechnological potential 5.
