Abstract
The current project was initiated to address the utilization of the lignin component obtained during the bioconversion of aspenwood wastes. This utilization is necessary for the economic viability of the whole conversion process. The lignin obtained from steam pretreatment has been suggested to be of low molecular weight, reactive, and offer great potential as a raw material for utilization. This is in contrast to the lignins from traditional pulping operations. However previous to this work, characterizati- on of lignin separated after steam pretreatment of aspenwood under varying conditions (with and without acidic catalysts), has not been undertaken to substantiate these widely held beliefs. Neither has anyone identified the production of the type of lignin most suitable for various applications. A prerequisite for utilization of this material, therefore, has been to undertake this necessary characterization. A major emphasis of the work during this first year has been placed on the establishment of the analytical capability required to achieve the above goals. Following discussions with other researchers, such as Glasser and Lewis (Virginia Tech.), Chum (SERI), etc. we are confident the analytical methodology we have in place for lignin characterization and the assessment of planned modification reactions is as good as any other laboratory in the world.

Abstract
Over 100 strains of wood-rotting fungi were initially screened for their celllulase and B-glucosidase activities. Some of these strains were assayed for extracellular cellulase activity using a variety of different solid media containing carboxymethyl cellulose or acid swollen cellulose. The diameter of clearing of these plates gave an approximate indication of the order of cellulase activities obtained from culture filtrates of these strains. Trichoderma strains grown on Vogel's medium gave the higher cellulase yields. Culture filtrates from Trichoderma sp. E58 demonstrated the highest B-glucosidase activity giving a value of 1.1 IU/mg. A variety of different cellulose and pretreated wood substrates were hydrolysed using Trichoderma culture filtrates. The importance of the pretreament conditions and ensuing chemical extractions of the cellulosic substrates was demonstrated by the range of ethanol values obtained in simultaneous saccharification and fermentation experiments using Zymomonas mobilis or Saccharomyces cerevisiae. The rate of hydrolysis of the cellulosic substrates by Trichoderma culture filtrates, concentrated culture filtrates and whole cell cultures was compared. An ethanol value of 2.2% (W/V) was obtained from 5% solka floc using concentrated culture filtrates of Trichoderma and Z.mobilis or S.cerevisiae.

Abstract
Various parameters affecting the overall conversion of lignocellulosics to ethanol were studied. Of prime importance in a lignocellulosics to ethanol process is the pretreatment of the woody biomass. We have found that high levels of hydrolysis (92%) can be achieved with material that was acid soaked prior to steam-explosion and water extracted after steam explosion. This hydrolysis was accomplished through a combined hydrolysis and fermentation technique which produced, under optimum conditions, a broth containing 2.3% ethanol. Optimum conditions for the combined hydrolysis and fermentation process were found to be a culture pH of 4.8, a hydrolysis temperature of 45C and a fermentation temperature of 37C. Yeast extract was found to be inhibitory to the action of the cellulases and was only added following the hydrolysis step.

Abstract
The biomass yield per hectare predicted for the Dawson Creek TSA is 32.3 oven-dried tonnes per hectare (odt/ha) from harvest residues. The biomass ratio, which is the ratio of recovered biomass to recovered merchantable roundwood, is estimated at 19.2%. Over the next 10 years at total of 1.59 million odt of available biomass are predicted to be generated by harvest in the Dawson Creek TSA, or approximately 160,000 odt/yr. Of this, approximately 1,242,000 odt in total, or 124,000 odt/yr, is expected to be available at the economic price of $60 per oven-dried tonne. Approximately 98% of the total predicted volume is expected to be available at $90/odt: a total of 1.56 million odt, or 156,000 odt/yr.

Abstract
The average harvest residue biomass yield per hectare predicted for the Fort St. John TSA is 31.5 oven-dried tonnes per hectare (odt/ha). Over the next 10 years, a total of 2.99 million odt of available biomass are predicted to be generated by harvest in the Fort St. John TSA, or approximately 300,000 odt/yr. Of this, approximately 269,000 odt in total, or 27,000 odt/yr, is expected to be economically available at a price of $60 per oven-dried tonne. Approximately 75% of the total predicted volume is expected to be available at $90/odt, representing a total of 2.25 million odt, or 225,000 odt/yr.
