Effects of UV Radiation on Melanization and Growth of Fungi Isolated from Weathered Wood Surfaces
2015 - IRG/WP 15-10842
This research tests the hypothesis that fungi isolated from weathered wood will respond to elevated levels of UV radiation by increasing their melanin production. To test this hypothesis, we measured the melanin production and mycelial color of Aureobasidium pullulans and Cladosporium cladosporioides, before and after the fungi were grown under artificial UV, visible light and complete darkness.

Three dimensional computer representations of growth of microbial populations in wood
1984 - IRG/WP 1243
Creosoted distribution poles inoculated with either Lentinus lepideus, biological control organisms including Triochoderma or combinations of both were extensively sampled to monitor the spread of organisms. A computer program which enabled the results to be portrayed in a three dimensional graphic form was developed and is illustrated. Results showed that computer mapping of this type usefully en...

Discoloration of pressure impregnated wood caused by Amorphotheca resinae
1990 - IRG/WP 1438
Amorphotheca resinae Parbery with the anamorph Cladosporium resinae (Lindau) von Arx & de Vries is a cosmopolitan fungus known from aviation kerosene, hydrocarbon contaminated soil and creosoted timbers. In Denmark it causes heavy discoloration on wood treated with waterborne chromate-containing preservatives e.g. CCA-oxide type. The teleomorph produces small spherical fruitbodies widespread o...

Evaluation of a new anti-sapstain formulation
1994 - IRG/WP 94-30035
A new anti-sapstain mixture, which consists of 2% IPBC (3-iodo-2-propynylbutyl carbamate) and 1.5% DCOI (4,5-dichloro-2-n-octylisothiazolin-3-one), was evaluated by three methods in the laboratory. A standardized test (JWPA standard 2) demonstrated that the new anti-sapstain formulation was highly effective in controlling growth of monocultures of five test fungi on wood substrate. When exposed to...

The selected properties of Scots pine wood blue-stained by fungus Cladosporium herbarum
2003 - IRG/WP 03-10484
The fungi causing primary blue-stain of wood may change wood properties especially when acting in mixture of few fungi species. There were been undertaken investigation to clear the influence of pure culture of one fungus species on selected physical and mechanical properties of Scots pine wood. The twin samples of fresh cut Scots pine sapwood (Pinus sylvestris L.) were exposed into pure culture o...
