[[File:Bacteria upgrades.png|thumb|right|200px|New Bacteria upgrades appear in the menu as you purchase more [[Colonies|colonies]] (v. 1.1.2)]]
Bacteria upgrades give various multipliers to global [[BPS]], [[BPC]], as well as increase the production of different [[Colonies|'''colonies''']].
The player unlocks new bacteria upgrades by purchasing more colonies. After purchase, Bacteria upgrades cannot be sold or disabled. An option to buy all Bacteria upgrades is unlocked after destroying [[Lableilara]].
Most upgrades can only be bought once, but some are '''iterative'''. Iterative upgrades usually become available after the player has bought 200 of one colony type. Afterwards, they can be purchased once per 25 new colonies.
For [[BPS]] colonies, there is also a second tier of iterative upgrades, which becomes available per each 1000 colonies owned and provides a 500000% increase for the production of that colony.
Currently, there is only one iterative bpc upgrade and it is unlocked after obtaining 200 [[Colonies#Bacteria Guns|'''Bacteria guns''']] and it can be purchased again after each 25 new Bacteria guns.
All bacteria upgrades are lost when attacking a [[Planets|'''planet''']] or entering a '''[[Black Hole]]'''.
