    The effect of natural product treatment of southern yellow pine on fungi causing blue stain and mold2014In: International Biodeterioration & Biodegradation, ISSN 0964-8305, E-ISSN 1879-0208, Vol. 86, no B, p. 54-59Article in journal (Refereed)
    Abstract [en]

    Blue stain and mold growth on wood can be aesthetically unappealing, but mold growth can also potentially trigger health related issues. In this study, a screening of the effect of selected natural products and derivatives of natural products including essential oils, plant based monomers, and shellfish exoskeleton compounds on the inhibition of blue stain fungi and mold fungi in southern yellow pine veneers and cellulose filter paper. The treatment of the substrates, the weight percent gain of the natural products, and the inhibition effect is presented. The natural products have been investigated previously, but most have not been applied to wood or investigated with regards to blue stain or mold growth. The specimens were treated by dipping, wrapping in foil, and then heating at 105°C for 24h in order to encourage reaction or grafting of the natural products to the wood. A selection of seven additives each exhibited significant protection against blue stain colonization in Petri dish tests and these were studied more in-depth. These included tea tree oil, propyl gallate, hydrogenated gum oil, salicylic acid, cinnamon bark oil, butylene oxide, and furfural. The salicylic acid, tea tree oil, and cinnamon bark oil had the least amount of mold growth after four weeks in the mold chamber test, and have been previously reported to have a mechanism of antifungal activity resulting from their ability to disrupt the fungal cell wall. Propyl gallate veneer was the only specimen that had a lower pH and that would be considered unfavorable to mold growth. While furfural, salicylic acid, and cinnamon bark oil treated veneers all had more hydrophobic surfaces when compared to untreated wood.

    Evaluation of spent mushroom substrate as substitute of peat in Chinese biobeds2015In: International Biodeterioration & Biodegradation, ISSN 0964-8305, E-ISSN 1879-0208, Vol. 98, p. 107-112Article in journal (Refereed)
    Abstract [en]

    Biobeds are an effective system for minimising the risk of point-source contamination by pesticides. The original biobed system comprises a clay layer at the bottom, a biomixture layer and a grass layer on top. The composition of the biomixture, which in the original Swedish model consisted of soil: peat: wheat straw (1:1:2 by volume), determines the efficiency of the system. Since the use of peat is not environmentally or economically feasible in China, this study tested the potential of replacing it with a locally available material, spent mushroom substrate (SMS). Three biomixtures containing different SMS (Pleurotus eryngii, Flammulina velutipes and Lentinus edodes) were compared with a biomixture containing peat, as in the original Swedish design, and a control containing soil alone. The fungicide chlorothalonil and the insecticide imidacloprid were used as model pesticides in the tests. Microbial activity (measured as respiration and phenoloxidase and hydrolytic activity) and pesticide dissipation were studied. Microbial activity was higher in the three biomixtures containing SMS than in the original-type biomixture. Among the SMS biomixtures, that containing SMS from L.edodes was the most biologically active. However, pesticide dissipation was comparable in all four biomixtures and significant differences were only found between biomixtures and the soil-alone control. Based on the physicochemical characteristics, biological activity and preliminary results on pesticide degradation, SMS are suitable and can therefore be used as a substitutes for peat.

    Effect of wood modification on gene expression during incipient Postia placenta decay2014In: International Biodeterioration & Biodegradation, ISSN 0964-8305, E-ISSN 1879-0208, Vol. 86, no B, p. 86-91Article in journal (Refereed)
    Abstract [en]

    The mode of action of nontoxic wood modifications and the fungal response to modified wood are not fully elucidated. The aim of this study was to investigate the reaction of Postia placenta in terms of gene expression of selected genes upon the encounter of acetylated, DMDHEU-treated and thermally modified wood. Quantitative PCR (qPCR) showed that the investigated P.placentagenes involved in oxidative degradation were expressed at higher levels in modified wood than in untreated wood, while expression levels in modified wood for the investigated genes involved in enzymatic degradation were slightly lower than those in untreated wood. The results indicate that the response of P.placenta upon the encounter of modified wood is to up-regulate the expressionof the oxidative degradation machinery. In addition, our results support the theory that the decay resistance of the herein studied modified woods is due to inhibition of fungal molecules, needed for oxidative degradation of wood polymers, to penetrate the wood cell wall.

    Fungal durability of polyaniline modified wood and the impact of a low pulsed electric field2014In: International Biodeterioration & Biodegradation, ISSN 0964-8305, E-ISSN 1879-0208, Vol. 87, no Febr, p. 26-33Article in journal (Refereed)
    Abstract [en]

    New wood protection technologies should be effective against biodeterioration and at the same time minimize environmental impact. The present study investigates the effect of polyanilinemodification of wood and the effect of a pulsed electric field on fungal protection. The effect of fungi and a pulsed electric field on the conductivity of the modified wood was also measured. It was found that it is possible to polymerize polyaniline particles in-situ homogeneously throughout the wood specimens. The polyaniline particles themselves were not found to be anti-fungal, however when in contact with water they affected the pH drastically and inhibited fungal growth. The wood treatment with polyaniline and the connection to a pulsed electric fieldwere found to be effective in protecting the wood from deterioration when exposed to Postia placenta. The unmodified samples that were connected to a pulsed electric field lost under 10wt% due to fungal degradation. The combination of polyaniline treatment with the connection to a pulsed electric field showed a slight synergistic effect which resulted in less weight loss due to fungal degradation. However, a more brittle wood structure was observed.Leached and fungal exposed samples showed a significant drop in the conductivity, indicating that the network has broken down slightly.

    Monitoring of fungal colonization of wood materials using isothermal calorimetry2017In: International Biodeterioration & Biodegradation, ISSN 0964-8305, E-ISSN 1879-0208, Vol. 120, p. 43-51Article in journal (Refereed)
    Abstract [en]

    We have developed a method based on isothermal calorimetry to monitor the colonization of wood materials by decay fungi. The heat produced is a direct and continuous measure of the activity (respiration) of the fungus. This pre-study shows that wood materials treated in different ways give results that reflect the known ranking of the materials regarding resistance to decay. In addition to this, the 40 days measurements show several phases and periods of oscillating respiration. As the calorimeter continuously monitors the colonization and degradation process, this method provides more information than classical/standardized decay tests in which typically only the final mass loss is determined.
