Brown Rat

Brown Rat (Rattus norvegicus) is classified as Least Concern (LC) on the IUCN Red List. Widespread and abundant across its range, with stable populations and no immediate conservation concerns.

Sphingobacterium zeae is a Gram-negative, yellow-pigmented rod first isolated from corn plants, as its species name implies. It inhabits the phyllosphere and rhizosphere of maize and related crops. This aerobic chemoheterotroph degrades plant-derived organic matter and may play roles in plant-associated microbiome functions.
