Submerged fermentation was carried out for the production of scleroglucan by Sclerotium rolfsii MTCC 2156 using complex media, such as coconut water, sugarcane molasses and sugarcane juice at 28 +/- 2 degrees C and 180 rpm for 72 h. Sugarcane juice gave maximum scleroglucan production of 23.87 g/l as compared to 12.58 and 18.45 g/l with coconut water and sugarcane molasses, respectively. Utilization of these substrates would be ecologically sound and economically advantageous. (c) 2006 Elsevier Ltd. All rights reserved.
