1. Ethanol from woodCellulase enzyme production
Abstract : Conversion of biomass to liquid fuels, such as ethanol, has been investigated during the past decades. First due to the oil crisis of the 1970s and lately because of concerns about greenhouse effect, ethanol has been found to be a suitable substitute for gasoline in transportation. READ MORE

2. Ethanol Production from Cellulosic Biomass by Encapsulated Saccharomyces cerevisiae
Abstract : Unstable oil markets with rising environmental concerns have revived widespread interest in production of fuel ethanol from renewable materials. Cellulosic materials are abundant and prominent feedstocks for cheap ethanol production. However, due to recalcitrant structure of these materials, pretreatment is a prerequisite. READ MORE

3. Integration of filamentous fungi in ethanol dry-mill biorefinery
Abstract : The industrial production of bioethanol as a replacement to gasoline is well-established worldwide, using starch- or sugar-rich substrates. Additionally, the bioethanol plants produce animal feeds derived from fermentation leftovers. The biorefinery character of bioethanol plants can be enhanced via process diversification. READ MORE

4. Development of the Steam Pretreatment Process for Production of Ethanol from Lignocellulosic Biomass
Abstract : At a time when natural petroleum resources are on the verge of depletion, and concern about climate change is increasing, the potential of lignocellulosic material for the production of bioethanol is well recognized. Ethanol can be produced from biomass through enzymatic hydrolysis and fermentation. READ MORE

5. Conversion processes for biofuel production
Abstract : Despite the global positive impacts of soybean-, maize- and sugarcane-based (first-generation) liquid biofuels, several drawbacks pertaining to increased use of agricultural land, causing deforestation in some countries and extensive practice of fertilizers have been observed. As a result, developing advanced (second- and third-generation) liquid biofuels have been identified as better alternatives and are considered to be of great importance in the future. READ MORE
