Can you use the card nitrate reducing bacteria as your second action of a turn when you play it? it comes into play with 3 nitrate counters .
which you could use as another action to remove them to advance your terraforming rating.+1
the next time you would be able to activate it is after three more full turns to put counters on it(essentially +4 turns)?
Yes you can and should or at least use it in a later turn in the same generation.
