DEVELOPMENT OF BIOETHANOL PRODUCTION FROM SUGARCANE BAGASSE USING NEUROSPORA INTERMEDIA ON SOLID STATE CULTUREELVI RESTIAWATY*, LINEA ALFA ARINA AND YOGI WIBISONO BUDHIAbstract Sugarcane bagasse is one of the potential agro-industrial residues in Indonesia. The aim of this research was to evaluate the potency of sugarcane bagasse as main carbon source and solid culture media for N.intermedia to produce bioethanol. The content of solid culture media was varied, i.e. sugarcane bagasse, soybean, and the mixture of both carbon sources media (with the ratio of bagasse: soybean = 9:1). The initial amount of spore influenced the specific growth rate of N. intermedia. The bioethanol production was influenced by the initial concentration of spore and the composition of solid media. The highest yield of bioethanol was obtained from the solid-state fermentation using the mixture of sugarcane and soybean and with 4.0 g·L-1 fresh spore solution of Neurospora sp, resulting 79% (w/w theoretical) bioethanol yielded, followed by soybean and bagasse fermentations, reaching 50% and 26.14% (w/w theoretical), respectively.
