1. Bio-processing of preservative-treated timbers Various wood-decaying fungi, molds and staining fungi were evaluated for their bioremediation activities against preservative-treated timbers. Recovery rates of metals from the treated timbers strongly varied with fungal species. Non-biological agents, chitin and chitosan were also found to be effective heavy-metal scavengers2. Effective production of biogases with termites Effective methods for regulating intestinal micro-fauna and/or -flora were developed by food selection and the antibiotics treatments. In the case of Coptotermes formosanus, the maximum 112 emission rate of 17.5 nmol/termite/h, which is equal to 10L/one million population colony/day, was obtained when fed on antibiotics-treated cellulose. In addition, xylan was effectively fermented by the suspension of the intestinal micro-flora of Nasutitermes takasagoensis, emitting 100 times higher H2 than in intact termites.3. Biogases from termites and fungi as tools for detection Various gas sensors were evaluated for their applicability as tools for detection of biological deterioration. The hydrogen sensor was found to be an effective tool to detect termite activities in the monitoring station used for the bait system. Some decay fungi were also observed to emit considerable amount of CO as a metabolic gas, which might be used as an indicator of decay.4. The effective bioconversion of wood and wood-based materials by microorganisms Molecular breeding of the white rot fungus, Pleurotus ostreatus, by homologous exression of its versatile peroxidase MnP2 was conduced, and the genetically modified strain successfully degraded the polymeric dye PolyR-478 and benzopyrene. The pretreatment of Cryptomeria japonica by white rot fungi followed by the yeast fermentation resulted in the stable ethanol production

1.防腐处理木材的生物处理各种木材腐朽真菌，霉菌和染色真菌对防腐处理木材的生物修复活性进行了评价。金属的回收率从处理过的木材强烈不同的真菌种类。非生物制剂，甲壳素和壳聚糖也被发现是有效的重金属清除剂2。用白蚁有效地生产酶通过食物选择和抗生素处理开发了调节肠道微型动物和/或-植物群的有效方法。以台湾乳白蚁为例，当饲喂杀虫剂处理的纤维素时，112的最大释放速率为17.5nmol/白蚁/h，相当于10 L/100万种群菌落/天。此外，高砂鼻白蚁肠道菌群的悬浮液能有效发酵木聚糖，释放出比完整白蚁高100倍的H2.白蚁和真菌的生物气体作为检测工具各种气体传感器的适用性进行了评估，作为检测生物变质的工具。氢传感器被认为是一种有效的工具，检测白蚁活动的监测站用于诱饵系统。一些腐烂真菌也会释放出大量的CO作为代谢气体，这可能是腐烂的一个指标.利用微生物对木材和木质材料进行有效的生物转化对同源表达多功能过氧化物酶MnP 2的白色腐菌Pleenostreatus进行了分子育种，并成功地对聚合染料PolyR-478和苯并芘进行了降解。柳杉经白色腐菌预处理后，再经酵母发酵，乙醇产量稳定
