Brown Rat

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.
