Cassava based bioethanol production is a promising alternative to conventional fossil fuels and commercial production is already well established in several countries. A production based on small holder production may involve a transformation of the existing production system and it is therefore...

Hydrolysates from olive prunings (a renewable, low-cost, easily available, agricultural residue) were fermented with the unconventional yeast Candida tropicalis NBRC 0618 to produce not only ethanol fuel but also xylitol as a by-product, which adds value to the economic viability of the...

Cellulose hydrolysis is an important step in the production of bioethanol from lignocellulose. Using enzymes, as a biocatalyst, is expected to have a lower utility cost compared to the conventional acidic hydrolysis because it is carried out at milder conditions and does not require subsequent...

To investigate the bioethanol production from sweet potato, the saccharification and fermentation conditions of co-immobilization of saccharolytic molds (Aspergillus oryzae and Monascus purpureus) with Saccharomyces cerevisiae were analyzed. The immobilized yeast cells showed that at 10% glucose...

Bioethanol is a promising biofuel and has a lot of great prospective and could become an alternative to fossil fuels. Ethanol fermentation using glycerol as carbon source was carried out by local isolate, ethanologenic bacterium Escherichia coli SS1 in a close system. Factors affecting...

Red algal biomass is a promising alternative feedstock for bioethanol production, due to several advantages including high carbohydrate content, growth rate, ethanol yield, and CO2 fixation ability. However, it has been known that most yeast strains can not utilize galactose, the major sugar of...

The EU imports both bioethanol and the raw material needed to produce it. Thirty percent of bioethanol is produced from sugar beets in the EU. However, sugar beet cultivated area and yields have fallen due to the 2006 sugar regime reform. Given the potential uncertainty about the future for...

Increasing energy use and the need to mitigate climate change make production of liquid biofuels a high priority. Farmers respond worldwide to this increasing demand by converting forests and grassland into biofuel crops, but whether biofuels offer carbon savings depends on the carbon emissions...

Energy crops constitute significant potential for meeting the future energy need worldwide. In addition, agricultural lands offer an alternative to the agriculture which is referred to as energy farming. The studies on energy crops in biofuel production show that they are quite an economical and...

Bioenergy from lignocellulosic biomass offers the potential to provide a significant source of clean, low carbon and secure energy. In recent years, a number of studies have been carried out to assess the environmental performance of lignocellulosic ethanol fuel. However, the complexity of...
