| ABSTRACT |
The invention discloses a process for efficient production of biofuel comprising the steps of preparing a hydroxyapatite (HAp) biomaterial for use in from of an immobilizer during a fermentation process, mixing the hydroxyapatite immobilizer with a saccharomyces cerevisiae yeast product to perform physical adsorption, placing the mixture into a bioreactor for performing fermentation of immobilized yeast in presence of the hydroxyapatite (HAp) immobilizer and obtaining bioethanol produced from the fermentation of immobilized yeast in presence of the hydroxyapatite. The present method has several advantages including lower running cost of the operation and easy isolation of the biofuel product.
