with concentration of 10 g/L S. cerevisiae and 5 g/L Z. mobilis during fermentation. Z. mobilis showed a potential in fermenting xylose sugars that were mainly obtained during microwave-acid pretreatment. The obtained results in the present study proves that sweet sorghum bagasse is a very good feedstock for producing bioethanol in South Africa, and that could have an impact in integrated food and energy systems
