This paper is all about the effective and most efficient method to be used in the production of bioethanol among all (i.e Physical, Chemical, and physico-chemical). As such from my studies to ease the long processes, chemical method using dilute-acid yielded high amount of the bioethanol compared to other methods. According to my findings, micro-organisms were screened appropriately and most suitable for the production was selected so as to achieve the aforementioned process.
