You get Axum Bacterial Culture by visiting the swamps behind the Alien Ruins Angel Comb in Subnautica 2. To reach that area, start from the Alien Ruins location and move east to the Angel Comb next to it. If you can't find the Alien Ruins, you can track the location by accessing the Signals' menu from the inventory tab. You can also track the Angel Comb to know exactly where you're going.

There's also a Leviathan guarding the area above the lakes. So, stay near the ground and do not enter the swamp area with your Tadpole. If you do, it'll alert the Collector Leviathan, and it'll attack you.
