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.

Stenotrophomonas daejeonensis is a Gram-negative gammaproteobacterium in the family Xanthomonadaceae, first isolated from soil samples collected in Daejeon, South Korea. It is aerobic, rod-shaped, and motile by polar flagella. Like other Stenotrophomonas species, it exhibits broad enzymatic activity and has been isolated from diverse environments including soils, water, and clinical samples.
