Bio-Hydrogen Production Using Landfill Leachate Considering Different Photo-Fermentation Processes

Recently, it has become imperative to find new sustainable and renewable sources of energy, in order to avoid dependence on non-renewable traditional energy resources. This would help to overcome the depleting of natural resources for energy production. Hydrogen gas production using biological proce...
