Greetings friend, first of all I apologize for responding a little late, your comment is very valuable, endogenous microorganisms can be known in different ways depending on the region, I have seen name as functional microorganisms, efficient microorganisms among other names, what should be clear is that they are microorganisms that come from natural ecosystems and play a key role in agriculture.

Thank you for your recommendation, have a great start of the week.
