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...
This study was initiated to determine the tolerance to copper
of Aspergillus niger, Stemphylium sarcinaeforme, Monilinia
fructicola and Fusarium oxysporum f. sp. lycopersici. Included
were strains of the latter two fungi that were induced to tolerate
relatively high levels of copper by continual culture on sublethal
levels of the toxicant....
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...
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...
Polygalacturonase produced by Fusarium oxysporum f. sp.
lycopersici was purified by chromatography on DEAE cellulose, CM
cellulose, and hydroxylapatite. Removal of large amounts of carbohydrate
by chromatography on hydroxylapatite did not affect heat
stability of the enzyme. A large proportion of the remaining carbohydrate
appeared to be covalently linked to...
