Azospirillum canadense is a free-living nitrogen-fixing alphaproteobacterium in the family Rhodospirillaceae, first isolated from Canadian corn rhizosphere soil. It is capable of colonizing plant roots and fixing atmospheric nitrogen, potentially stimulating plant growth as a biofertilizer. Like other Azospirillum species, it produces phytohormones including indole-3-acetic acid that promote root growth and nutrient uptake.

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.
