Lignocellulosic biomass is a plentiful and renewable resource for fuels and chemicals. Despite this potential, nearly all renewable fuels and chemicals are now produced from edible resources, such as starch, sugars, and oils; the challenges imposed by notoriously recalcitrant and heterogeneous lignocellulosic feedstocks have made their production from nonfood biomass inefficient and uneconomica...

111 We present a computable general equilibrium model of the interface between the Great Salt Lake (GSL) ecosystem and the regional economy that impacts the ecosystem. With respect to the ecosystem, the model treats the various representative species as net-energy maximizers and bases population dynamics on the period-by-period sizes of surplus net energy. Energy markets-where predators and pre...

Rosemary (Rosemarinus officinalis L.) is a well-known medicinal and essential oil plant, utilized by humankind since ancient times. The objective was to determine the effect of steam distillation time (DT) and material (dry or fresh biomass) on essential oil yield, composition, and bioactivity; and to develop regression models that can predict oil yield and composition at specific DT. The oil y...

The conditions for continuous cultivation of Bacillus megaterium on a collagen-derived substrate (SP-100) were determined. The optimum conditions of temperature, pH, and dilution rate were 34 C, pH 7.0, and 0.25/hr, respectively. Increasing the substrate concentration in plain tap water resulted in proportional increases in the productivity of cell mass from 0.6 g per liter per hr at 1% substra...

Crude glycerol is the primary byproduct of the biodiesel industry. Producing docosahexaenoic acid (DHA, 22:6 n-3) through fermentation of the alga Schizochytrium limacinum on crude glycerol provides a unique opportunity to utilize a large quantity of this byproduct. The objective of this work is to investigate the effects of impurities contained in the crude glycerol on DHA production and algal...

The paper examines contracts in new agricultural industries that exhibit learning-bydoing. A dynamic model analyzes a contract’s effect on production decisions, as well as investments in processing capacity and learning. The results of the model are applied qualitatively to the biomass electricity industry. Submitted by: Conrad J. Choinière Dept. of Agricultural and Resource Economics Universit...
