Bioethanol from Napier grass employing different fermentation strategies to evaluate a suitable operation for batch bioethanol production

Napier grass has been used as animal feed especially in countries with tropical climates. As interest in alternative feedstocks for fuel bioethanol increases, Napier grass has been considered as a potential feedstock for lignocellulosic bioethanol production. Two main fermentation strategies, includ...
