PEMODELAN PRODUKSI BIOETANOL OLEH SACCHAROMYCES CEREVISIAE DENGAN SUBSTRAT GLUKOSA

Petroleum resource depletion demands the development of mass-producible alternative energy sources. Bioethanol is one of the easiest examples of renewable energy to implement. Bioethanol is produced by fermentation using the yeast Saccharomyces cerevisiae.This study will determine the effect of diff...
