Abstract

Photobiological hydrogen production is the most challenging research since the world’s energy demand is increasing, fossil fuel resources are being reduced and the greenhouse that needs reduction of gas emissions is increasing. Hydrogen gas is a clean and efficient energy carrier that produces zero emissions and can be produced by managing renewable resources such as biomass and waste. Biological methods of hydrogen production are preferable to chemical methods because of the possibility of using sunlight. It is predicted that hydrogen gas will be effective not only in terms of being clean energy, but also in the establishment of extra- terrestrial life. However, the eco-friendly bacteria used for this purpose belongs to the non-sulfur photosynthetic bacteria such as Rhopseudomonas and Rhodobacter that metabolizes extraordinary carbon sources. Raw materials such as organic-based starches, cellulose-containing solid wastes obtained from different industrial wastewater or industrial wastes etc. can be used as sources, for hydrogen production as well while the waste is being treated. This work will create a process that supports the continuity of the environment in recycling and will provide significant efficiency in both a healthy environment and healthy life. This paper focuses on the importance of hydrogen production and how the recycling of waste is important for energy production by using photosynthetic bacteria.
