Abstract

In view of the technical and biological limitations of open pond systems, a study was conducted to develop a cost-effective experimental photobioreactor that would permit efficient cultivation of microalgae for biodiesel production. The photobioreactor was developed using low cost materi- als, cylindrical translucent tubes and plexiglass. The photobioreactor prototype was equipped with alternative arrangement for light source: solar and fluorescent bulb light. It provides uniform illumination by sunlight and a centrally located fluorescent light powered by electricity and rechargeable dry cells. The 12-chamber photobioreactor each measuring 122cm tall and 36cm in diameter approximately 12 liters; in all, occupies a minimal demand on land area. The 12-chamber photo-bioreactor produced approximately 430gram/day with the application of 2.4 litres of liquid poultry droppings.
