Exiguobacterium aurantiacum is an orange-pigmented, Gram-positive bacterium first isolated from a potato-processing plant, producing vivid carotenoid pigments that protect it against oxidative stress. It is a versatile, stress-tolerant organism found in a range of environments from food processing facilities to environmental soils. Members of Exiguobacterium are noted for extremotolerance, surviving wide temperature and pH ranges.

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.
