Consumption of ethanol produced from biomass carries wide opportunity to reduce the use of gasoline and cut CO2 emissions. According to The National Development and Reform Commission, the biomass availability in Malaysia and its potential energy generated are 50,919 dry kton/year and 13,343 kton/year for 2011. Therefore, the fermentation of waste banana branch cellulose with various local fungi include Schizophyllum commune, Pycnoporus sanguineus, Micropus xanthopus, Perenial Ganoderma lipsiense, Microporus affinis, Microporus xanthopus and Mycena sp has been investigated for their ability to produce bioethanol. The production patterns of fermentation were studied during the growth of the organisms for a period of interval of two day until day 10. The cell wall breaking banana branch cellulose has been done using the technique of ultrasound bath. The resulted bioethanol generation has been referred by ethanol standard calibration of refractive index. Among seven types of the collected fungi, fermentation yield resulted maximum 11% volume ethanol which represented by Perenial Ganoderma lipsiense fungi at day 2. Very low levels of bioethanol production were detected by the Microporus affinis fungi. The 11% yield percent of ethanol produced by the experiment show the better ability of alternative fungi for bioethanol industry compared to conventional fungi, yeast which also being included as a standard of fungi fermentation.
