How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Converting lignocellulose to bioenergy and biobased products requires targeted breakdown of complex plant polymers that protect structural sugars. To identify lignophenolic compounds that promote enzymatic hydrolysis, the lignophenolic composition of biomass across 12 species and varieties of the Poaceae (grass) family were measured using copper (I...
As part of an integrated energy and climate system, biomass production for bioenergy based on the tropical perennial C4 grass energycane can both offset fossil fuels and store soil carbon (C). We measured energycane yields, root biomass, soil C pools, and soil C stocks in a four‐year field trial and modeled C flow from plants to soils in the surfac...
Experimental conditions of liquid hot water (LHW) pretreatment were tested for two dedicated energy crops, Napiergrass (Pennisetum purpureum) and Energycane (Saccharum officinarum × Saccharum robustum). Both crops showed differential resistance to temperature during pretreatment and differences in response to biomass and enzyme loadings during subs...
Effective soil management is critical to achieving climate change mitigation in plant-based renewable energy systems, yet limitations exist in our understanding of dynamic belowground responses to the cultivation of energy crops. To better understand the belowground dynamics following cultivation of a grassland in a high-yielding tropical perennial...
The natural capacity of the terrestrial landscape to capture and store carbon from the atmosphere can be used in cultivated systems to maximize the climate change mitigation potential of agricultural regions. A combination of inherent soil carbon storage potential, conservation management, and rhizosphere inputs should be considered when making lan...
Bioenergy feedstock selection for maximizing conversion efficiency, climate change mitigation potential, and economic and environmental feasibility through conservation management practices. We measure field-based parameters of soil organic carbon and greenhouse gas flux and partner with agronomists, engineers, economists, and our stakeholders to collaborate on systems-level assessment of viability for bioenergy and biofuel production in Hawaii.
