Utilization of Switchgrass As A Biofuel Feedstock
نویسنده
چکیده
In the first part of the thesis, chemical analyses were conducted for four populations of switchgrass, SW1-SW8. Each population consisted of 69% leaves, 27% internodes, and 4% nodes. The variations in carbohydrates, lignin, extractives content, Higher Heating Value (HHV), and syringyl:guaiacyl (S:G) ratio were determined among the populations and the morphological portions. The experimental results suggest that each population of switchgrass has a similar chemical profile, while the profiles of the morphological portions differ. The leaf portions have the highest arabinose, galactose, ash, and lignin contents and the lowest S:G ratio, while the internode portions have the highest values of these variables. The internode portions have the highest glucose content (44.3%).

Using Switchgrass for Forage
Switchgrass is a warm-season perennial grass native to much of the United States. Over the last few years, switchgrass has received renewed interest as a renewable fuel source, since it produces large amounts of cellulose that can be digested and converted to ethanol. The high yields and environmental adaptability of switchgrass make it an excellent choice for biofuel feedstock production. Whil...
متن کاملPotential ecological impacts of switchgrass (Panicum virgatum L.) biofuel cultivation in the Central Great Plains, USA
Switchgrass (Panicum virgatum L.) is a broadly adapted warm-season grass species native to most of the central and eastern United States. Switchgrass has been identified as a potential biofuel species because it is a native species that requires minimal management, and has a large potential to sequester carbon underground. Since the 1990’s, switchgrass has been bred to produce cultivars with in...
متن کاملUse of Fly Ash as Soil Amendment for Biofuel Feedstock Production with Concomitant Disposal of Waste Accumulations
Increasingly higher costs of disposal of fly ash (FA) on the one hand, and on the other, the current focus on bioenergy offer opportunities for using FA as soil amendment for producing biofuel feedstock while cleaning up accumulations of the product. Greenhouse pot experiments were conducted in a silt loam soil amended with 0%, 2.5% and 20% FA to determine boundary shoot and root biomass produc...
متن کاملThe Biofuel Feedstock Genomics Resource: a web-based portal and database to enable functional genomics of plant biofuel feedstock species
Major feedstock sources for future biofuel production are likely to be high biomass producing plant species such as poplar, pine, switchgrass, sorghum and maize. One active area of research in these species is genome-enabled improvement of lignocellulosic biofuel feedstock quality and yield. To facilitate genomic-based investigations in these species, we developed the Biofuel Feedstock Genomic ...
متن کاملGene flow matters in switchgrass (Panicum virgatum L.), a potential widespread biofuel feedstock.
There currently exists a large push for the use, improvement, and expansion via landscape modification of dedicated biofuel crops (feedstocks) in the United States and in many parts of the world. Ecological concerns have been voiced because many biofuel feedstocks exhibit characteristics associated with invasiveness, and due to potential negative consequences of agronomic genes in native wild p...
