Wood Deterioration

Based on present knowledge of the origin, amounts, chemical form, and distribution of nitrogen (N) in wood, hypotheses are proposed to explain radial gradients in N content that exist across the xylem cylinder of tree stems: (1) N in the cytoplasm of developing wood cells is diluted by apposition of cell wall substances; (2) after maturation of wood fiber cells, N in their cytoplasm is removed by elution into the transpiration stream; (3) death of xylem parenchyma cells during aging of sapwood and formation of heartwood is accompanied by removal of much of the N in their cytoplasm. Hypotheses 2 and 3 above suggest strongly that trees possess an internal recycling mechanism for conservation and reuse of the N in the cytoplasm of xylary cells.Although the supply of N in wood is meager, wood-destroying fungi readily metabolize the carbon-rich constituents of wood and produce large fruiting structures that release vast numbers of spores in nature. To account for these capacities, we postulate that these fungi employ one or more of the following three mechanisms: (1) preferential allocation of N obtainable from wood to substances and pathways highly efficient in the use of wood constituents; (2) reuse of N obtainable from wood by a dynamic and continuous process of autolysis and reuse without significant loss of N; (3) utilization of N sources outside the wood itself, for example, by fixation of atmospheric N.

Wood deterioration were generally occured by the activities of biological agents. Fungal can attack wood and lignoselulosic substances and cause staining and decaying. Its damage levels were vary depending on the attacking fungal species. Eventhough it poses some disadvantages, actually fungy have potential benefits for human life such as nutrient, energy resources, medicine, etc. Fungy from Tabo-tabo educational forest were collected, isolated,and identified in this study. Identification was conducted throughout their macroscopic and microscopic characteristics. The result showed that the amount of fungal species were nineteen species, i.e: Aspergillus sp.,Poria subacida, Fomes sp., Lenzites sp., Hericium sp., Dacrymyces deliquescens, Ganoderma lucidum, Clitocybe sp., Trametes confragasa, Shizophyllum commune, Periconia sp., dan Helicosporium sp.,Clitocybe sp., Schizophyllum commune, dan Hygrophorus hypotejus,Ganoderma lucidum dan Coprinus atramentarius, Amanitopsis fulva dan Dacrymyces deliquescens, Collybia sp., Amanitopsis fulva, Hygrophorus hypotejus,Coprinus atramentarius, Monilia sitophilia, Gilmaniella sp. dan Conoplea sp.

Milicia Excelsa

Wood usage has increased with time, thus, there is need to investigate how wood can be treated with human and environmentally friendly preservative which is effective in protecting wood from termites and other agents of wood deterioration, or improve the wood physical, chemical, mechanical and biological characteristics. The aim of this study was therefore to evaluate the effects of neem oil on Milicia excelsa wood preservation. Treated and untreated pieces of Milicia excelsa wood samples were used to carry out this experiment, a soil bed, and an internal wood exposure to termite’s test was carried out, and measurements taken using a digital weighing machine. The results obtained showed that, when Milicia excelsa is treated with neem oil, its Rate of Decay (ROD) reduces as compared to the untreated pieces. Also, neem oil treated wood when exposed to termite’s attack experiences a slower weight loss compared to untreated samples with significant weight loss. Neem oil is thus not only effective in preserving woods, but also non- toxic to human and the environment.
