91% of the energy consumed worldwide is supplied by hydrocarbons, which are also a major source of income for some of the Latin American countries, including Mexico. The problem is aggravated with the increase in the demand of energy due to the steady population growth. For this reason, the new energy policies are moving towards diversifying sources of energy, in particular, the use of renewable energy. One possible solution, is the use of hydrogen which can be obtained from renewable sources such as biomass to generate clean energy for small towns. It has been shown that some groups of fermentative bacteria have the ability to generate hydrogen from simple sugars. A chromatographic study was performed to determine the presence of biogas in the gases produced by the natural fermentation through some of the involved bacteria, and subsequently, by microscopy to characterize the bacteria images in fermentative processes. Samples were taken from the natural alcoholic drink pulque; of prehispanic origin. These studies demonstrated the feasibility of the use of this biogas to produce energy in the form of hydrogen without altering the natural fermentation conditions of the drink itself.
