Mould growth at lumber surfaces of pine after kiln and air drying
1994 - IRG/WP 94-40033
…by Theander et al. (1993) it has been indicated that the growth of the mould fungi Penicillium brevicompactum and Aspergillus versicolor is positively correlated with the content of nitrogen and low-molecular carbohydrates. Kiln and air drying cause redistribution of the soluble sugars and nitrogen in different…

Comparison of the effects of borate, germanate and tellurate on fungal growth and wood decay
1992 - IRG/WP 92-1533
The tetra-hydroxy borate ion is known to undergo complexation with polyols and has been shown to inhibit dehydrogenase enzymes in this way. It has been previously suggested that this complexation is responsible for the inhibition of fungal growth and the protection of boron…
