Lighter organic hydrogen gas.

In the present patent we describe an innovative lighter organic hydrogen gas working by microbial activities and the fermentation of organic substrates. The lighter comprising a container having a refill valve, a release valve of the gas to be turned on and a button that controls the release valve, and ignition means suitable to trigger the combustion of hydrogen with oxygen outside air; it is characterized in that the container has a partition wall permeable to only gas which divides said container into two sections, a first section containing a support on which adheres a biomass consisting of fermenting liquids mixed in microorganisms (heterotrophic bacteria or anaerobic non-photosynthetic bacteria/photosynthetic algae), which is positioned in the first section of the refill valve and a second section that contains the hydrogen gas produced by said microorganisms and the drain valve of the gas that is opened by the manual device. More, the lighter organic hydrogen gas is characterized in an inert and non-biodegradable support with cross-linked structure on which adheres the microbial biomass. When lighter organic hydrogen gas works by phototropic microorganisms the container is made of transparent material; otherwise, if lighter organic hydrogen gas works in dark fermentation, the container is made of non-transparent material and heterotrophic bacteria are used.
