A PROCESS FOR MICROBIAL FERMENTATION OF SUGARY SUBSTRATES AND USE OF THE HYDROGEN IN ATOMIC, IONIC OR GASEOUS STATE IN SAID PROCESS

摘要

The present invention relates to a biochemical process for increasing selectively the production of alcohol through fermentation of sugary substrates by inoculating hydrogen into the microorganism in a fermentative process comprising sugary wort, nutrients and microorganism of the genus fungus or bacterium. The production of hydrogen occurs through application of an electric voltage in pre-electrolysis or full electrolysis, under direct or alternating electric current, in the fermentative medium. The use of hydrogen in atomic, ionic or gaseous state for inoculation into the microorganisms present in a fermentative medium for the selective production of alcohol is also described.
