Abstract: The various thermophilic strains were isolated from the soil samples collected from the dumping site of sugarcane bagasse and screened by using phenol red broth. Only one microorganism showed fermentation activity on all the substrates except lactose and cellulose. This strain was selected for further fermentation studies and characterized as yeast Kluyveromyces sp. IIPE453. The yeast strain showed the growth and fermentation on glucose, mannose, galactose, xylose, sucrose, cellobiose and lactose. The optimum conditions for growth and fermentation were found to be 50 °C temperature and 5.0 pH. About 92 % of the sugars present in the bagasse biomass could be recovered by acid hydrolysis in two steps, firstly with dilute acid to hydrolyze hemicelluloses and then with concentrated acid to hydrolyze cellulose. Fermentation of the bagasse hydrolysate with Kluyveromyces sp. IIPE453 was studied separately for hydrolysates obtained by dilute acid hydrolysis and by concentrated acid hydrolysis.
