Where to find axum bacterial cultures in Subnautica 2

Subnautica 2 players can collect five axum bacterial culture pieces in a dangerous deep area east of the Alien Ruins and Angel Comb.

The cultures do not respawn, so each piece is a one-time pickup and easy to miss.

They are used with a blueprint and mangalloy ingots to craft metal farms.

Because the chain is limited and valuable, wasting a piece can permanently reduce access to ore production.
