[Digestion] Biochemical route to hydrogen and ammonia

[Steve]

    Dear List
    
    Does anyone on the list have any knowledge about producing molecular
hydrogen using microorganisms?  The textbook, 'Biomass for Renewable Energy,
Fuels and Chemicals' by Donald L. Klass indicates experimental energy yields
as hydrogen of approx. 8% (from dry pea shells).  
    
    Have there been any advances in producing hydrogen from biomass via
microorganisms?  Has anyone looked at innovate routes to ammonia production
using biomass?
