Water hyacinth (Eichhornia crassipes) represents a promising candidate for fuel ethanol production in tropical countries because of their high availability and high biomass yield. Bioconversion of such biomass to bioethanol could be wisely managed through proper technological approach. In this work, water hyacinth was used as a substrate for bioethanol production by the use of thermophiles. Water hyacinth was pretreated with sulfuric acid (1 M) and sodium hydroxide (1M) for release of free sugars. | Effect of saccharification methods on bioethanol production by thermophiles from Eichhornia crassipes
