Introduction:

Bioprocess engineering science is a big field of science, where four of different major subjects such as chemical engineering, Molecular Biology and Biotechnology, Biomedical Science, and Engineering Material; work together in harmony to solve many difficult problems which is possible to face the scientist in Biomedical Science, energy product, nutrition and designing devices such as bioreactors [1], With modified and added.

Bioreactor is one of the most familiar words in bioprocessing engineering's books. Which mean a place which is designed to be suitable for the growth of specific types of bacteria, fungi or other microorganisms by provision of the necessary conditions for its growth [2]. These microorganisms are doing biochemical processes that produce useful materials for humanity, Such as some kinds of medicines, enzymes and fuel. In this case the fuel which made by microorganisms is called bio fuel [3]. Bio fuel often is environmentally friendly, and has many advantages such as it is cheap, it is a renewable power resource and it is product able easily. On the other side it has some negative point such as it need a lot of time to make few litter of bio fuel when we use the normal method to produce it. In this project some points of designing devices, methods and technology of bioreactors and using it to producing bio fuel will be discussed.

Uses of Bioprocess Engineering:

1-Some important points before starting bioreactor project:

First of all, and before starting design or work on any bioreactor, some points that relate with the future of the bioreactor project should be cleared. One of these point is that what is the output that we want to reach, which is must be a very useful things and...

The fourth production method is the dark fermentation system which uses the Fermentative bacteria which can produce hydrogen all the time without light or oxygen. The main drawback for this mode is that the output gas mixture contains carbon CO2 which has to be separated. Also there is a decrease in the H2 production.

Conclusion:

In conclusion, because of the limitation of fossil fuels and the damaging which caused by it, the world today is really need to clean renewable power resources, to save the planet and to have a save future . This clean resource can be found easily in biotechnology and bioprocess engineering studies which include a lot of different researches and innovative solutions for the most important condition of powering and developing.
