Having a large varied biomass of bacteria maximizes the types and amounts of nutrients exported out of your system. A single type of bacteria is suited for what it requires while many different species cover the whole spectrum.

That being said, very little is known on the relationship between Bacteria and their surroundings, this is something that is currently being studied. Most of the bacteria supplements we add to our tank are nitrobacter or Nitrosomonas but here is a statement from Ency. Britannica to give you a little info.

any of a small group of aerobic bacteria (family Nitrobacteraceae) that use inorganic chemicals as an energy source. They are microorganisms that are important in the nitrogen cycle as converters of soil ammonia to nitrates, compounds usable by plants. The nitrification process requires the mediation of two distinct groups: bacteria that convert ammonia to nitrites (Nitrosomonas, Nitrosospira, Nitrosococcus, and Nitrosolobus) and bacteria that convert nitrites (toxic to plants) to nitrates (Nitrobacter, Nitrospina, and Nitrococcus).
