Resumen:
Current processes used for the production of hydrogen consume a great part of the energy
they produce and/or depend on fossil fuel consumption, making them inefficient and
harmful to the environment. Obtaining hydrogen from living systems by fermentation of
organic matter considered waste is a promising alternative for the future. Especially when
you take into account that the biological production of hydrogen is intrinsically linked to
the degradation of said organic matter. In this paper, we explore the efficiency of different
bacterial communities (also called consortia) for anaerobic fermentation of carbohydrates.
The evaluated consortia were obtained from soil, commercial compost and sludge from
a sewage treatment plant. The cultures that produced the highest amounts of hydrogen
were those in which the inoculums used came from sludge and compost. Both reached
a maximum accumulated concentration of approximately 30% of biological hydrogen in
the gas mixture on day 8 of the fermentation process, as estimated by gas chromatography.
