The hydrolyzed or partially hydrolyzed medium with organic material is then fermented in the presence of at least one microorganism capable of ammonification, wherein the fermenting is under conditions, and for a sufficient period of time, to produce a fermentation product that comprises ammonia or ammonium. The organic material includes nitrogenous compounds suitable for conversion to ammonia or ammonium.
