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: In 1980, Costa Rica spent the income from its coffee production entirely on the purchase of petroleum products. Fully aware of the dilema facing it, the government has placed top priority on satisfying its energy requirements from its own renewable natural resources. One means of achieving this would be the establishment of agro-industrial complexes for the industrialization of sugar cane operations to produce not only sugar but also alcohol and other cane products and of the cane acreage to support it. These other cane products will likely include panel building materials, lignin-based resins, animal feedstock and fuel. Morrison, Hershfield, Burgess and Huggins Limited (MHBH), on behalf of a group of Canadian companies, has requested financial support for a feasibility study for the integrated industrial utilization of sugar cane in Costa Rica. The members in this group of companies are prepared, and competent, to implement the capital project which the feasibility study will examine.; Evaluation; Sugar Cane; Utilization; Options; Morrison, Hershfield, Burgess, Huggins Limited (MHBH)

Abstract: The purpose of this work was to assess the morphological development of a filamentous fungus, Schizophyllum commune grown in media supplemented with various carbon sources, in an attempt to correlate cellulase gene regulation with the morphogenesis of the fungus. Daily samples of fungal cultures grown for up to eleven days were supplied by the Molecular Genetics Group, National Research Council of Canada. The cultures were investigated using optical and scanning electron microscopy. This report describes the general morphogenesis of submerged cultures of S. commune grown on soluble and solid carbon substrates. The colony development, asexual spore formation and substrate utilization by the fungus are also described.

Abstract: Scanning electron microscopic observations of treated and untreated wood residues of poplar and eucalyptus were carried out. We hoped to evaluate the different methods of treatment and study the effect that different conditions such as temperature, time, pressure and chemicals have on the physical modification of the wood residues. It was observed that wood samples which had been treated by continuous acid hydrolysis in a Cascade reactor at temperatures below 243C and discharge pressure below 4000 psi had little effect on the wood structure. At a moderate discharge pressure (2975 to 2500 psi), the degree of wood disruption increased with the increase in reactor temperature; thus more of the wood tissue was reduced to wood fibers and fiber bundles at 223C than at 208C. Although wood samples retained in the ractor for shorter times than 100 sec showed insignificant morphological changes, longer retention times may increase the outflow of lignin from the cell wall layers. Tetrahydrofluran was shown to remove the lignin deposits in the treated wood. Wood samples discharged from the reactor and subsequently washed with tetrahydrofluran showed clean fiber surfaces and separation of the fibers as fault lines developed among the fiber bundles. The wood samples of E. saliqua were more resistant to pretreament as compared to the samples from poplar wood. The process of liquefaction was shown to effectively alter the wood structure of poplar. The poplar wood chips which were treated at 320C for 5min followed by discharging at 520 psi contained shattered tissue fragments and associated spheres. Cellulose microfibrils however were not found in these treated wood samples.
