koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.

Sphingobium quisquiliarum is a Gram-negative aerobic rod with the capacity to degrade polycyclic aromatic hydrocarbons and phenolic compounds found in contaminated environments. It has been isolated from compost and organic waste materials. This bacterium participates in the bioremediation of aromatic organic pollutants in its compost or soil habitat.
