Abstract:

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. Acid pretreatment was most effective in comparison to alkali treatment that resulted in formation of 1.73 mg/ml reducing sugar. The sugars after pretreatment produced maximum 4.1 gm/l ethanol by Bacillus vietnamensis strain and 3.58gm/l by Bacillus stearothermophilus. Thus, the experiment imparts an economic value to water hyacinth that are cleared from choking waterways.
