Bacterial biodegradation of extractives and patterns of bordered pit membrane attack in pine wood

Article Abstract:

Several bacterial species can remove wood extractives from wood chips prior to the paper making process. Southern yellow pine chips lost 40% of their wood extractives over a 14-day period when treated with Pseudomonas fluorescens, Pseudomonas sp., Xanthomonas campestris, and Serratia marcescens. The treated wood was not stained during the process.

Wood-destroying soft rot fungi in the historic expedition huts of Antarctica

Article Abstract:

An investigation carried out to evaluate wood decay present at the three historic huts in the Ross Sea region, identify fungi isolated from the decayed wood by using internal transcribed spacer (ITS) sequences of ribosomal DNA (rDNA), to determine where these fungi are located in the historic huts, and evaluate their decay potential in laboratory studies, is presented. The results of the study may provide information crucial to conservators for preservation of these historic sites as well as new information on decay fungi and elucidate the type and extent of degradation that has occurred.

Biological processing of pine logs for pulp and paper production with Phlebiopsis gigantea

Article Abstract:

Phlebiopsis gigantea was inoculated on Pinus resinosa and Pinus gigantea pine logs to determine the efficiency of the saprophytic fungus in the biological processing of pine logs into paper and pulp. Inoculation of logs with Phlebiopsis gigantea after cutting induced extensive colonization which induced pitch degradation and increased cell wall porosity. The effects of the white rot fungus on pine logs also improved pulping efficiency.
