Engineering of Bioethanol Production Bioprocess from Bladygrass Using Yeast and Zymomonas mobilis Co-culture Techniques
In this study bioethanol was made by fermentation with the help of yeast co-culture and Zymomonas mobilis. The co-culture itself produces better bioethanol than using a single culture (monoculture) which usually uses Saccharomyces cerevisiae microorganisms. The use of Zymomonas mobilis also produces better results than using Saccharomyces, which is bioethanol obtained more optimally.
The purpose of this study was to obtain alternative bioprocess technology from reeds using the technique of yeast tape co-culture and Zymomonas mobilis which produced higher ethanol concentrations compared to the production process without co-culture.
