Starkeya

Starkeya is a genus of Gram-negative, non-spore-forming bacteria belonging to the family Xanthobacteraceae. These bacteria are known for their ability to utilize specific sulfur compounds as energy sources, particularly thiosulfate.

Starkeya species are typically rod-shaped and motile, possessing flagella. They are commonly found in soil and aquatic environments, playing a role in the biogeochemical cycling of sulfur. Some species have also been isolated from extreme environments.

The genus Starkeya was originally classified within the Thiobacillus group but was later reclassified based on phylogenetic analyses and distinctive physiological characteristics, notably their ability to utilize specific organic sulfur compounds. Key characteristics that differentiate Starkeya from other related genera include their unique metabolic capabilities and genomic features.

Research on Starkeya is often focused on its role in sulfur cycling, its potential applications in bioremediation of sulfur-contaminated environments, and its ecological significance in various habitats. The genus name honors Dr. Robert Starkey, a prominent soil microbiologist who made significant contributions to the study of sulfur-oxidizing bacteria.
