Brook Alder

The Brook Alder (Alnus maritima) is a species in the genus Alnus. It is currently classified as Endangered on the IUCN Red List. Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Sphingopyxis granuli is a Gram-negative alphaproteobacterium in the family Sphingomonadaceae, characterized by its yellow-pigmented colonies and the presence of sphingolipids in its membrane—a trait shared across the family. It was isolated from granule-associated material and is aerobic, rod-shaped, and motile. Sphingopyxis species are common in soils, freshwater, and plant-associated environments.
