Pseudoalteromonas

Pseudoalteromonas is a genus of Gram-negative, aerobic, and halophilic bacteria. It was first described in 1998 as a result of reclassification of the genus Alteromonas. The name "Pseudoalteromonas" is derived from the Greek words "pseudo," meaning false, and "alteromonas," referring to the original genus. These bacteria are widely distributed in marine environments, including coastal waters, sediments, and seaweeds. They are known for their ability to produce a variety of bioactive compounds, such as antibiotics, antifouling agents, and antimicrobial peptides. Pseudoalteromonas species are also recognized for their role in the degradation of organic matter and their potential use in bioremediation. They are motile by means of polar flagella and can form biofilms, which contribute to their ecological success. The genus Pseudoalteromonas includes over 30 recognized species, with Pseudoalteromonas atlantica being one of the most studied due to its potential applications in biotechnology.
