Production of bioethanol from coconut (Cocos nucifera) husk by enzymatic hydrolysis using Aspergillus niger / Anis Athirah Bahri

Coconut (Cocos nucifera) husk were abundant in Malaysia and it was employed as raw material in production of bioethanol. The conventional ethanol from petroleum-based would cause environmental hazard and it was known as nonrenewable resource. The objectives of this study to synthesis bioethanol from...
