Water hyacinth (Eichhornia crassipes) is a very common weed that degrades inland water bodies and responsible for drastic water pollution. This weed possesses about 80% of cellulose within it which is a polysaccharide of the monomeric β-D glucose. Glucose is a good substrate for the production of bioethanol. This process can be accelerated using some microbial strains which are well documented. The microbes that can grow on the water extract of water hyacinth are believed to utilize cellulose as the organic carbon source. These microbes were isolated from the water hyacinth extract and plated on CMC agar and PDA media to get the pure culture. The bacterial colonies were found on CMC media resembled the Actinomycetaceae family and were used as the inoculating culture of the bioethanol production. The small scale pilot fermentation process, without the help of any bioreactor, was carried out using the water hyacinth as a raw material for one month. The presence of ethanol was confirmed using Iodoform test. The process was replicated to confirm the reliability of the results. This bioethanol production process may prove to be cheaper and eco-friendly.

Abstract


Water hyacinth (Eichhornia crassipes) is a very common weed that degrades inland water bodies and responsible for drastic water pollution. This weed possesses about 80% of cellulose within it which is a polysaccharide of the monomeric β-D glucose. Glucose is a good substrate for the production of bioethanol. This process can be accelerated using some microbial strains which are well documented. The microbes that can grow on the water extract of water hyacinth are believed to utilize cellulose as the organic carbon source. These microbes were isolated from the water hyacinth extract and plated on CMC agar and PDA media to get the pure culture. The bacterial colonies were found on CMC media resembled the Actinomycetaceae family and were used as the inoculating culture of the bioethanol production. The small scale pilot fermentation process, without the help of any bioreactor, was carried out using the water hyacinth as a raw material for one month. The presence of ethanol was confirmed using Iodoform test. The process was replicated to confirm the reliability of the results. This bioethanol production process may prove to be cheaper and eco-friendly.
