Sphingopyxis alaskensis is a marine Gram-negative bacterium originally isolated from cold Alaskan coastal waters, reflecting its geographic origin. It inhabits cold, oligotrophic ocean environments and can grow at very low nutrient concentrations. This ultramicrobacterium is adapted to nutrient-poor cold marine conditions and decomposes dissolved organic matter.
