Available in PDF, EPUB and Kindle. Book excerpt: As our global population and environmental awareness increase, so does our demand for renewable, sustainable energy. The US Department of Energy has established the Energy Independence and Security Act of 2007, which mandates a total of 36 billion gallons of renewable fuel needs to be produced and blended into transportation fuel by 2022. The Act also requires that 21 billion gallons of produced renewable fuel needs to be derived from non-cornstarch material. Every year in the United States, approximately one billion dry tons of cellulosic feedstock is produced which can be used to generate biofuels. However, the process of converting cellulosic biomass into biofuel involves enzymatic hydrolysis, which contributes to a large portion of cellulosic biofuel production cost in terms of enzyme production-- it is responsible for 20-40% of cellulosic ethanol production cost. To make this alternative energy more economically friendly, reducing the cost of enzyme production needs to be investigated. This research project explores and compares the production of cellulase enzymes via traditional Trichoderma reesei, ethanol-inducible transgenic tobacco, and transient agroinfiltrated tobacco. The conceptual plant designs for each production process are assumed to annually produce 3.2 million kg of cellulase enzymes, assuming 100% active cellulase enzymes, to meet the on-site or nearby ethanol production of 61 million gallons (231 million liters) of ethanol simulated in the Humbird et al. technical report. The technoeconomic studies are modeled using Microsoft Excel and SuperPro Designer software. For each production process, early environmental and economic assessments were calculated and compared. With the early environmental assessment developed by Biwer and Heinzle, it was found that the three production processes all consist of an overall low environmental impact. Economically, fungal production would have an advantage over the field-grown, plant-based productions, due, in part, to the limited growing period (late March to late October) for growing tobacco outdoors which restricts host production to only 59% of the year. Under these assumptions, in order for plant-based productions to be as competitive as fungal production, transgenic production needs to either increase its plant density to 152 metric ton of fresh weight (FW) plant biomass/ ha or increase its expression level to 4.49 g of cellulase enzymes/ kg FW plant biomass; and transient production needs to increase its plant density to 159 metric ton of FW plant biomass/ ha and increase its expression level to 7.88 g of cellulase enzymes/ kg FW plant biomass.
Download or read book Approaches to Enhance Industrial Production of Fungal Cellulases written by Manish Srivastava and published by Springer. This book was released on 2019-04-26 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellulase is a key enzyme of industrial interest and plays a crucial role in the hydrolysis of cellulose, a prime component of plant cell walls. Cellulase covers a broad area in the global market of industrially important enzymes and it is considered as the third largest industrial enzyme globally. Additionally, cellulase contributes about 20% of the total enzyme market globally because of its massive demand in various industries such as in biofuel production, pulp, paper, textile, food, and beverages, as well as in detergent industries. Among these, the demand of cellulase may become frequently selected in the commercial production of biofuels in the future and thus will further increase demand of cellulase in the biofuel industry. Because biofuel production is still not realized in a cost-effective, practical implementation due to its high cost (the higher cost of biofuels is due to higher production costs of enzymes), there is a need to introduce these types of approaches, which will help to lower the cost of enzyme production for developing overall economic biofuel production.
