METHOD FOR OBTAINING A MICROBIAL CONSORTIUM IN ORDER TO PRODUCE HYDROGEN AND HYDROLYSATES USING COMPLEX SUBSTRATES.

摘要

The present invention relates to a method for obtaining a stable and robust microbial consortium or inoculum, which produces hydrogen and hydrolysates for the generation of methane as an energy source in biological production systems using complex substrates, specifically agroindustrial waste, industrial wastewater, urban solid organic waste and lignocellulosic materials. The method of the invention ensures the production of an inoculum having a microbial structure with the following advantages: reproducible on a large scale; highly robust, predominance over the microflora native to the substrates; high hydrolytic capacity; generates natural anaerobic conditions, without requiring the injection of an inert gas or the addition of a chemical reducing agent; highly stable, viable for up to 2 years when refrigerated; and reactivation time measured in hours.
