“…Many research studies have been carried out on the chemical modification of wood using anhydrides and focused on decay resistance of modified wood. Iwamoto and Itoh (2005) reported that the MA treated sugi sapwood (Cryptomeria japonica D. Don) carried in a vapour phase reaction system at concentrations of vapour phase MA at 4 and 8 × 10 -3 mol·l -1 had strong resistance against fungal decay. The MA studied here is known to form covalent bonds with OH groups of wood (Iwamoto, Itoh 2005).…”

The MA studied here is known to form covalent bonds with OH groups of wood (Iwamoto, Itoh 2005). By reducing free OH groups in wood, the sorption of water in the cell walls is prevented, the wood moisture content is reduced and the resistance of wood to fungal attack is increased.…”

“…Maleic anhydride treated wood samples and untreated samples were inoculated with 50 µl of the spore suspension of A. niger PSU1, A. flavus PSU2 or (Iwamoto, Itoh 2005) P. citrinum PSU3 on surface and incubated at 25°C and 100% relative humidity (RH). The fungal growth on the surface of the wood samples was observed weekly for 52 weeks.…”

“…The chemical modification of wood using di-and tricarboxylic acid anhydrides has been reported (Papadopoulos, Hill 2002;Iwamoto, Itoh 2005). Treatments of wood with various organic anhydrides have the potential to increase fungal resistance and to replace the use of biocides for wood preservation (Schiopu, Tiruta-Barna 2012).…”

ABSTRACT:The rubberwood samples were treated with 0.5-10% maleic anhydride (MA) solutions. The treatment of wood with 2.5% MA was adequate to prevent the growth of moulds on wood for 1 year at least. The viable count of Aspergillus niger van Tieghem PSU1 on MA treated wood indicated that fungal spores were not killed. The maleic anhydride treated wood slices had no antifungal activity. The concentration of MA released from treated wood in the leachate was 0.02 mg·m -3 . Agar well diffusion showed that the leachate from MA treated wood had no antifungal activity. However, after leaching MA treated wood still had a high resistance to mould growth. The moisture contents of MA treated and untreated wood samples were not significantly different. The MA treated wood showed almost a smooth surface while the untreated wood showed a rough surface. The cytotoxicity test showed that the leachates of both MA treated and untreated wood samples had a similar effect. So the treatment of rubberwood with MA is a safe method to prevent mould growth.
