Optimization and Performance of Covered-Light Structures for Hydrogen Production by Rhodopseudomonas palustris TN1

In recent times, hydrogen production from agro-industry wastewaters using photosynthetic bacteria have been widely studied. Most research has been done with various light sources under uncovered-light structure resulting in light energy losses. Aims of this study are the following parameters; type o...
