Extraction of nitrogen from organic materials through ammonification by mixed bacterial populations

摘要

The invention provides a process for producing ammonia or ammonium from an organic material by fermenting a medium comprising organic material in the presence of a mixed bacterial population 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.
