Biohydrogen production from fermentation of sweet sorhgum (Sorghum biocular L) by Interobacter aerogenes ADH-43 in the packed-bed reactor

Hydrogen gas (H2) is one of a clean energy because its combustion produces only water vapor and heat, and leaves no carbon emissions. H2 gas is an energy future that promises both from the aspect of social, economic, or environmental. One of potential raw material for H2 gas production is Sweet sorg...
