Ce ph\u00e9nom\u00e8ne complexe se d\u00e9roule en trois \u00e9tapes m\u00e9taboliques au sein de ces bact\u00e9ries:<\/p>\n

    \n
  1. Le grossissement par photosynth\u00e8se,<\/li>\n
  2. La conversion du glycog\u00e8ne en plus petites mol\u00e9cules carbon\u00e9es par la glycolyse,<\/li>\n
  3. Puis, fermentation de ces produits avec formation de CO2 et de produits hydrog\u00e9n\u00e9s NADH et NADPH et combinaison par une hydrog\u00e9nase avec formation d’Hydrog\u00e8ne<\/li>\n<\/ol>\n

                                         L’US Air Force va subventionner plusieurs laboratoires am\u00e9ricains, avec comme chef de file celui du Dr Charles Dismukes, de l’Universit\u00e9 de Princeton. L’objectif est de s\u00e9lectionner des microbes, de les modifier g\u00e9n\u00e9tiquement et de d\u00e9terminer les conditions pour optimiser la production d’Hydrog\u00e8ne. Le probl\u00e8me est complexe puisqu’il faut acc\u00e9l\u00e9rer les trois \u00e9tapes du processus grossissement, conversion, fermentation ana\u00e9robie. Il semblerait que pour l’instant, ce soit la troisi\u00e8me \u00e9tape qui soit la plus lente et qu’elle puisse \u00eatre acc\u00e9l\u00e9r\u00e9e par des stress de type chocs osmotiques.<\/p>\n","protected":false},"excerpt":{"rendered":"
