The flowers of the forest tree, mahula (Madhuca latifolia L.), is said to have high levels of fermentable sugars which could be harnessed as potential substrates for ethanol fermentation. At the Regional Center of the Central Tuber Crops Research Institute in India, researchers studied the fermentation of this substrate using free and immobilized cells of Saccharomyces cerevisae. In batch flask experiments, they obtained product yields between 148 g ethanol/kg to 205 g ethanol/kg..
