Creator:: McIntyre, Gary Allen
Abstract:: The main objectives of this study were to determine the effect of certain environmental conditions on the quantity of poly-galacturonase (PG) produced by V. albo-atrum, and to partially purify and characterize the PGs produced by this fungus in culture and in infected tomato plants. V. albo-atrum produced twenty times as...

Creator:: Englander, Carol Marcus
Abstract:: Mycelial growth of Endothia parasitica was stimulated by relatively high concentrations of CuSO₄ in potato dextrose agar medium (PDA). Stimulation of E. parasitica by the high levels of CuSO₄ and the relatively poor growth of this fungus on standard culture media suggested that stimulation might be due to interaction of...

Creator:: Zahora, Andrew Roy
Abstract:: Experiments were conducted to determine both the influence of wood moisture content on the fungitoxicity of methylisothiocyanate (MIT) to the wood-decay fungus Poria carbonica, and the ability of gelatin to safely en-capsulate MIT for efficient treatment of wood products. The fungitoxicity of MIT was studied by determining the product of...

Creator:: Guilford, Roger Kirby
Abstract:: The demand for new fungicides to control plant diseases has led to experimentation with both previously used and newly developed fungicides. Silver, an older but little used fungicide, was selected for evaluation because of its high toxicity to microorganisms. Silver nitrate and a silver electrolytic cell were tested as potential...

Creator:: Harman, Gary Elvan, 1944-
Abstract:: This study was undertaken to determine the sorts of polygalacturonases present in the culture filtrate of Fusarium oxysporum f. sp. lycopersici, to purify and characterize these enzymes, and to study any complexes that may form between polygalacturonase and carbohydrate not degraded by the enzyme. The polygalacturonase in culture filtrate consists...

Creator:: Przybylowicz, Paul
Abstract:: Influence of temperature and wood moisture content on spore germination and colonization of Douglas-fir (Pseudotsuga jnenziesii) heartwood by Poria carbonica basidiospores and chlamydospores was studied. Both spore types germinated and colonized wood at moisture contents above the fiber saturation point, but not below. Germination and wood colonization occurred at 22°C...

Full Text:: Douglas-fir Utility Poles During Air Seasoning Abstract approved: Redacted for privacy M. E. Corden

Creator:: Sexton, Camille Marie
Abstract:: Douglas-fir utility poles are routinely air seasoned before treatment with chemical preservatives. Basidiomycetous fungi invade these poles and may cause strength loss during air seasoning or later if treatment temperatures are insufficient to kill the decay fungi. The purpose of this study was to develop a rapid test to asses...
