Resumo(s)
The majority of thermal modification processes are at temperatures greater than 180 C,
resulting in a product with some properties enhanced and some diminished (e.g., mechanical
properties). However, the durability of thermally modified wood to termite attack is recognised as
low. Recent attempts at combining thermal modification with chemical modification, either prior to
or directly after the thermal process, are promising. Buffers, although not influencing the reaction
systems, may interact on exposure to certain conditions, potentially acting as promoters of biological
changes. In this study, two zwitterionic buffers, bicine and tricine, chosen for their potential to form
Maillard-type products with fragmented hemicelluloses/volatiles, were assessed with and without
thermal modification for two wood species (spruce and beech), with subsequent evaluation of their
effect against subterranean termites (Reticulitermes grassei Clément) and their symbiotic protists. The
effect of the wood treatments on termites and their symbionts was visible after four weeks, especially
for spruce treated with tricine and bicine and heat treatment (bicine HT), and for beech treated with
bicine and bicine and heat treatment (bicine HT). The chemical behaviour of these substances should
be further investigated when in contact with wood and also after heat treatment. This is the first
study evaluating the effect of potential Maillard reactions with zwitterionic buffers on subterranean
termite symbiotic fauna
