The accreditation you are looking for is in organic science.
Guano's / Organics in general are broken down over time by the microbes in the medium, enzymes help the digestion of material in your medium / res
Guano's don't "take 4 months to break down to a usable state" they do break down over a longer period of time, however the nutrients are readily available / useable & will become more available as the micro-herd processes it.
Experiment: Put exact amounts of guano in 2 separate containers just add water to one & add microbes & enzyme to the other. Make sure the TDS is the same in both containers. shake a few times a day to aerate for 2 or 3 days.
Result: The EC / TDS will be higher in the container that has enzymes & microbes because they released the elements from their bindings.
