C. Heat Treatments. Several woods have been heated under wet and dry heating conditions to determine the effect heat has on the decay resistance of these woods. Alaska-cedar, Atlantic white-cedar, bald cypress, Douglas-fir, mahogany, redwood, white oak, Sitka spruce, and western redcedar were heated under dry conditions or wet conditions at temperatures of 80-180°C for varying lengths of time. Boyce (11) found that dry heat at 100°C or steam heat at 120°C for 20 minutes had no effect on the decay resistance. Similar results were observed by Scheffer and Eslyn (12) in soil-block tests with Lenzites trabea for the heated softwoods and Polyporus versicolor for the heated hardwoods. 

Matsumura et al. (25) identified (Z,Z.,E)-3,6,8-dodecatrien-l-ol in extracts of the termite Reticulitermes flavipes and reported that this compound was a powerful releaser of trail following for workers. However, this compound is also produced by the fungus Lenzites trabea which infects the wood fed upon by R. flavipes. The significance of the dodecatrienol in the biology of this termite has recently been examined in considerable detail (26). 

To show that the decay resistance observed is caused by a bulking mechanism and not the toxicity of acrylonitrile or its reaction products, cyanoethylated wood was extracted with hot water (104) to show that the leachate had no toxic effects on Lenzites trabea. The leached blocks lost their decay resistance, which may be caused by the reaction of acrylonitrile with the ammonia catalyst that was used to form water-soluble polymers in the cell wall.

An extracellular endo-(1 4)-/3-D-glucanase has been isolated and purified via gel filtrations and ion-exchange chromatographies, from the culture fluid of Lenzites trabea grown on D-glucose and cellulose.The enzyme (mol. wt. 2.9x10 by gel filtration, pH optimum 4.4, temperature optimum 70 °C) was also found to hydrolyse xylan.
