Eurasian beaver

Eurasian beaver (Castor fiber) is classified as Vulnerable (VU) on the IUCN Red List. Facing a high risk of endangerment in the wild, with declining populations and increasing habitat pressure.

Sphingobacterium composti is a Gram-negative bacterium first isolated from compost material, as its species name implies. It inhabits decomposing organic matter in compost heaps and organic-rich soils. This aerobic chemoheterotroph actively participates in composting processes, degrading complex organic compounds including cellulose and proteins.
